Conditional Statement

The most commonly used conditional statement in C++ is the if statement. It contains a conditional expression and a true branch, and it may contain a false branch. The true branch is executed when the conditional expression is true. The false branch, if present, is executed when the conditional expression is false. The following program demonstrates the use of the conditional statement.

Note: The true branch of the if statement starts the execution after the starting brace { and executes all the statements until the ending brace }.

Syntax

if (conditional statement) // no semicolon here
{
// execution starts from here if the conditional statement is true


// until here
}
else
{
// if the true branch is not executed, then this part of the code is executed


// until here
}
