Looping in C Programming

                                           LOOPING

Loop is used in programming to repeat a set of statements.

Looping is of three types:-

1)while
2)do while
3)for

while:-(entry control loop or precondition loop)

SYNTAX=
intialization;
while(condition)
{
statement;
increment/decrement;
}
Eg-
#include<stdio.h>
main()
{
int n=10;
while(n>=1)
  {
   printf("%d\n",n);
   n--;
  }
}

do while:-(exit control loop or post condition loop)

SYNTAX=
intialization;
do
{
 statement;
 increment/decrement;
}
while(condition);
In do while loop condition is verified at last.
eg:- #include<stdio.h>
       main()
        {
          int a=1;
          do
            {
              printf("%d",a);
              a++;
            }
          while(a<=10);
       }

for:-

SYNTAX:-
for(intialization;condition;increment/decrement)
{
 statement;
}
eg:-
#include<stdio.h>
main()
{
int n;
for(n=1;n<=10;n++)
 {
   printf("%d ",n);
 }
}
