In case the condition evaluates to false, we move to the line of code after the if-block. If there are no curly braces {} after the if statement, only the first statement inside the if block is considered. Syntax- if (condition){// conditional code body} Here, The if keyword marks ...

Syntax if(condition) { // block of code to be executed if the condition is true } Note thatifis in lowercase letters. Uppercase letters (If or IF) will generate an error. In the example below, we test two values to find out if 20 is greater than 18. If the condition istrue, pri...
while the basic premise of else—providing an alternative code block if a condition is false—remains the same, syntax and usage can vary between programming languages. for instance, in c++, you write: ```cpp if (condition) { // code if condition is true } else { // code if condition...
