Looping in C programming language

Looping in C

in loop, statement will be executed sequentially. there are some syntax in loop. they are :

1. for loop
   is a repetation control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
   example :
   #include <stdio.h>
   int main ()
   {
   int a;
   for (a=0; a<=10; a++) {
   printf ("%d ", a);
   }
   return 0;
   }
   
   the result will be "0 1 2 3 4 5 6 7 8 9 10"
2. While loop
   while loop statement in c repeatdly executes a target statement as long as a given condition is teur.
   example :
   #include <stdio.h>
   int main ()
   {
   int a = 20;
   while (a<30)
   {
   printf ("%d ",a); a++;
   }
   return 0;
   }
   
   the output will be "20 21 22 23 24 25 26 27 28 29".
3. Do while loop
   do while will check its condition at the bottom of the loop. but for and while will check the loop condition at the top of the loop.
   example :
   #include <stdio.h>
   int main ()
   {
   int a = 0;
   do
   {
   printf ("%d ",a); a++;
   }
   while (a<10);
   return 0;
   }
   
   the output will be "0 1 2 3 4 5 6 7 8 9".
