How do you write a Pascal if statement?
if (a <= 20) then c := c+1 ; If the boolean expression condition evaluates to true, then the block of code inside the if statement will be executed. If boolean expression evaluates to false, then the first set of code after the end of the if statement (after the closing end;) will be executed.
How do you do a boolean in Python if statement?
