Loops in C language

For Loop -Most Useful Loops

for ( variable initialization; condition; variable inc/dec )

{
  Code to execute while the condition is true
}
While Loop - Simple Loops

while ( condition )

{

Code to be executed if the condition is true

}

Do While Loops - It is useful when we want to loop at least once

do

{
}

while ( condition );

Below is a simple c program which demonstrates the working of all three types of loops i.e for loop ,while loop and do while loop.

What is the difference between while loop and do while loop?

A while loop might never execute a statement if the expression is false but a do while will always execute the statement at least once.
