if


The if statement is used to perform an action depending on a condition. Syntax:

if(condition) // run code

The condition is boolean - true or false. 1 is true, and 0 is false. Here's a working example of the if statement:

if(i == 5) // run code

In this case i == 5 is the condition. If the variable i is equal to 5, the Relational Operator '==' will return 1 for true. If not, it returns 0 for false.

If the condition returns true, the code is run. But if the condition returns false, the statement or code block following the if statement will be ignored.
