Flow of Control

IF-ELSE

Here's the syntax:

 
if (some condition)
{
    do something;
}
else if (something other condition)
{
    do something else;
}
else
{
    do something default;
}

For example:

 
 
if (input > 0)
{
	printf("Input is postive\n");
}
else if (input < 0)
{
	printf("Input is negative\n");
}
else
{
    	printf("Input is zero\n");
}

Relational Operators:

< : less than

> : greater than

<= : less than or equal

>= : more than or equal

== : equal

!= : not equal

if (input > 0) { printf("Input is postive\n"); } else if (input < 0) { printf("Input is negative\n"); } else { printf("Input is zero\n"); }
