do...while loop C

// Program to add numbers until the user enters zero

#include <stdio.h>
int main() {
  double number, sum = 0;

  // the body of the loop is executed at least once
  do {
    printf("Enter a number: ");
    scanf("%lf", &number);
    sum += number;
  }
  while(number != 0.0);

  printf("Sum = %.2lf",sum);

  return 0;
}

correct while loop syntax in c

while(condition) {
   statement(s);
}

do while loop in c

//This program stops when a number greater than 10 is printed and prints that, value greater than 10
#include <stdio.h>
main()
{

    int a;
    do
    {
        printf("
Enter your value: ");
        scanf("%d", &a);
    } while (a<10);
    printf("Value greater than 10");
    
    
}

while loop in c

//While loop, for the largest of two numbers.
#include <stdio.h>
int main(){
	int a, b;
    printf("Enter Values a and b:
");
    scanf("%d %d", &a, &b);
    while (a < b){

do-while in c

#include <stdio.h>
int main()

	int j=0;
	do
	{
		printf("Value of variable j is: %d
", j);
		j++;
	}while (j<=3);
	return 0;
}

while loop C

// Print numbers from 1 to 5

#include <stdio.h>
int main() {
  int i = 1;
    
  while (i <= 5) {
    printf("%d
", i);
    ++i;
  }

  return 0;
}

C while loop

//the syntax of the while loop statement is: init; while(condition) {statement(s);inc/dec;}
//init=initialization
//inc=increment|incrementation formula is i++ or ++i
//dec=decrement|decrementation formula is i-- or --i
#include<stdio.h>
main()
{
	int n=0;
	while(n<=10)
	{
	printf("%d, ",n);
	n++;
    }
}
