In C programming there are 3 types of loop and they are while loop, for loop and do while loop.
While loop
In while loop the body is executed until the test condition become false.
Syntax:
while (conditiuon){ //statement inside while.}Example:
#include <stdio.h>int main() { int count = 1; while (count < 5){ printf("While loop in c\n"); count = count + 1; } return 0;}Multiplication table using while loop:
#include <stdio.h>int main() { int number; printf("Enter the number: "); scanf("%d", &number); int count = 1; while(count <= 10){ int product = number * count; printf("%d x %d = %d \n", count, number, product); count = count + 1; } return 0;}do while loop
Here the body of the loop is executed and then the condition is evaluated, if the condition is true the body of the loop is executed again.
syntax:
do { //body of loop } while(condition);Example:
int main(){ int count = 5; do{ printf("%d\n", count); count = count + 1; } while(count < 5); return 0;}for loop
Syntax:
for(initializationExpression; testExpression; updateExpression){//codee inside for loop.}Example:
int main() { for(int i=0; i<10; i++){ printf("%d ", i); } return 0;}Sum of whole numbers from 1 to 100:
int main() { int sum=0; for(int i=1; i<=100; i++){ sum=sum+i; } printf("%d", sum); return 0;}Sum of even numbers:
int main() { int sum=0; for(int i=2; i<=100; i=i+2){ sum=sum+i; } printf("%d", sum); return 0;}Top comments(0)
