Loops in C

When we want to perform a similar task multiple times, we can use the concept of loops.

Basically there are three types of loops in C language.

1. For loop

2. While loop

3. Do - While loop

We can also implement loops inside other loops which is known as nested loops concept.

For Loop : 

The syntax for the "for" loop is 

for ( initialization ; condition ; increment / decrement / changes )

{

        // Statements to be executed repeatedly

}

The for loop is executed repeatedly until the condition becomes false.

While Loop : 

The syntax for the "while" loop is 

while( condition )

{

        // Statements to be executed repeatedly

}

The while loop is executed repeatedly until the condition becomes false.

Do - While Loop : 

The syntax for the "do - while" loop is 

do

{

        // Statements to be executed repeatedly

}

while( condition );

The do - while loop is executed repeatedly until the condition becomes false. The do - while loop will execute the statements atleast once irrespective of the condition, whereas the for and while loops will execute the statements only if the condition is true.
