When An If Statement Is Placed Within The Conditionally Executed Code Of Another If Statement?

8. When an if statement is placed within the conditionally-executed code of another if statement, this is known as

nesting

.

What operator takes an operand and reverses its truth or falsehood?

When C++ is working with an operator it strives to convert the operands to the same type?

When C++ is working with an operator, it strives to convert the operands to the same type. When a program uses the setw manipulator, the iosetwidth header file must be included in a preprocessor directive. In C++, it is impossible to display the number 34.789 in a field of 9 spaces with 2 decimal places of precision.

What do relational operators allow you to do with numbers?

Terms in this set (22) Relational operators allow you

to compare numeric and char values and determine whether one is greater than, less than, equal to

, or not equal to another. >

Which statement allows you to evaluate a value and execute a block of statements based on an integer or single character input?

An if statement can be used to make decisions based on ranges of values or conditions, whereas

a switch statement

can make decisions based only on a single integer or enumerated value. Also, the value provided to each case statement must be unique.

What statement causes a function to end in C++?

A return statement

ends the execution of a function, and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call. A return statement can return a value to the calling function.

What is the value of the following expression false || true?

int x = 5

; int y = 6; int z = 8; Is the following expression true or false?

Does conditional operator take two operands?

The result of the conditional operator is the result of whichever operand is evaluated — the second or the third. Only one of the

last two operands is evaluated

in a conditional expression. Conditional expressions have right-to-left associativity.

When a function is called flow of control moves to the function’s prototype?

When a function is called, flow of control moves to the function’s prototype. A parameter is a special purpose variable that is declared inside the parentheses of a function definition.

Which of the following is not a valid C++ identifier?

The C++ does not allow punctuation characters such as $, % and @ within identifiers. Some of the valid identifiers are:

shyam, _max, j_47

, name10. And invalid identifiers are : 4xyz, x-ray, abc 2.

When an operators operands are of different data types?

If the operands are of different data types,

implicit promotion

occurs to convert the operands to the same data type. An operator that gives a Boolean value by evaluating the relationship between two operands.

Which of the following is valid relational operator?

< :

less than

.

<=

: less than or equal to. > : greater than.

What can be used to override the rules of operator precedence?

Parentheses

can be used to override the default evaluation. In this case, A equals 18 because the parentheses have higher operator precedence than the multiplication operator; the expression inside the parentheses is evaluated first, and the result is multiplied by two.

What is relational operator in Matlab?

Relational operators

compare operands quantitatively

, using operators like “less than”, “greater than”, and “not equal to.” The result of a relational comparison is a logical array indicating the locations where the relation is true. These are the relational operators in MATLAB

^®

. Symbol.

What are relational operators?

In computer science, a relational operator is

a programming language construct or operator that tests or defines some kind of relation between two entities

. … In languages such as C, relational operators return the integers 0 or 1, where 0 stands for false and any non-zero value stands for true.

When a condition in an if-then statements Tests true?

If condition is true, then

the statements following Then are executed

. If condition is false, then each ElseIf (if any) is evaluated in turn. If a true condition is found, then the statements following the associated Then are executed.

Which statement checks only the true condition of a program and comes to an end?

The Boolean expression after the if statement is called the condition. If it is true, then all the

indented

statements get executed.

How do you end a function in C++?

1. Call the exit function.
2. Call the abort function.
3. Execute a return statement from main .

For what values of the expression in an if statement block is not executed *?

The if-statement block is only not executed when the

expression evaluates to 0

.

Which of the following is a valid C++ array definition group of answer choices?

Which of the following is a valid C++ array definition? The correct answer is:

int scores

[10];

Which of the following is a valid way to declare a function?

A function declaration is made of

function keyword

, followed by an obligatory function name, a list of parameters in a pair of parenthesis (para1, …, paramN) and a pair of curly braces {…} that delimits the body code.

Which one of the following operators is the best choice when determining if a number is outside a range?

The ‘||’

logical operator

works best when testing a number to determine if it is outside a range.

Which statement allows more than one condition in an if statement?

Use two if statements if both if statement conditions could be true at the same time. In this example, both conditions can be true. You can pass and do great at the same time. Use an

if/else statement

if the two conditions are mutually exclusive meaning if one condition is true the other condition must be false.

What statement best describes a variable and its primary purpose?

What statement best describes a variable and its primary purpose?

A variable is a named storage location in the computer’s memory used

for holding a piece of information. This step will uncover any syntax errors in your program.

What is conditional operator in Verilog?

SystemVerilog. The conditional operator

?: chooses, based on a first expression, between a second and third expression

. The first expression is called the condition. If the condition is 1, the operator chooses the second expression. If the condition is 0, the operator chooses the third expression.

What is conditional operator in C++ with example?

The conditional operator is an operator used in C and C++ (as well as other languages, such as C#). The ?: operator

returns one of two values depending on the result of an expression

. If expression 1 evaluates to true, then expression 2 is evaluated.

What is the data type of the function’s return value?

A return is a value that a function returns to the calling script or function when it completes its task. A return value can be any one of the four variable types:

handle, integer, object, or string

. The type of value your function returns depends largely on the task it performs.

Is a dummy function that is called instead of the actual function it represents?

A stub

is a dummy function that is called instead of the actual function it represents. A driver is a program that tests a function by simply calling it.

Which is not valid identifier in C programming?

Thus,

float or double, and int

are invalid identifiers, whereas Double, Int, and INT are valid identifiers because the case of letters has been altered. If one or more characters in the name are in uppercase, it is a safe bet against a keyword being used as name of a variable. Where to Declare Variables in a Program?

What are the 3 conditional operators?

There are three conditional operators:

&& the logical AND operator

. || the logical OR operator. ?: the ternary operator.

What is the difference between defining and calling a function?

declare and define are the same

, and they mean when you write all the code for your function. At that point the function just sits there doing nothing. call is when you tell the JavaScript interpreter to run the code in your function.

How do you know if an invalid identifier is valid?

A valid identifier

must have characters [A-Z] or [a-z] or numbers [0-9]

, and underscore(_) or a dollar sign ($). for example, @javatpoint is not a valid identifier because it contains a special character which is @. There should not be any space in an identifier. For example, java tpoint is an invalid identifier.

Which is not valid identifier?

Only alphanumeric characters (a-z, A-Z, 0-9) (i.e. letters and numerals) and the underscore(_) sign are allowed in an identification. The names of the identifiers must be unique. An alphabet or underscore must be the first character.

Keywords cannot

be used as identifiers.

Which of the following operators precedence order is correct?

Explanation: The Precedence of the operators is nothing but the priority given to each operator in an expression.

What is the precedence of operators?

The precedence of an operator

specifies how “tightly” it binds two expressions together

. For example, in the expression 1 + 5 * 3 , the answer is 16 and not 18 because the multiplication (“*”) operator has a higher precedence than the addition (“+”) operator. Parentheses may be used to force precedence, if necessary.

What is the order of precedence of operators?

Operators are listed in

descending order

of precedence. If several operators appear on the same line or in a group, they have equal precedence. All simple and compound-assignment operators have equal precedence. An expression can contain several operators with equal precedence.

What is the difference between operator and operands?

The operators indicate

what action or operation

to perform. The operands indicate what items to apply the action to.

Which of the following is a combination of operands and operators in a program?

The combination of operands with an operator to produce a result is called

an expression

.

Why is it important to know what is operator and operand?

Operators and Operands. Operators are

a fundamental part of all the computations that computers perform

. Understanding them is a prerequisite for understanding program behavior and for solving problems with programs.
