In this C program, we will learn about how to print natural numbers from 1 to N using for loop, while loop and do-while loop.
Required Knowledge
C program to print natural numbers from 1 to N using for loop
#include <stdio.h> int main() { int counter, N; printf("Enter a Positive Number\n"); scanf("%d", &N); printf("Printing Numbers form 1 to %d\n", N); for(counter = 1; counter <= N; counter++) { printf("%d \n", counter); } return 0; }
Output
Enter a Positive Number 10 Printing Numbers form 1 to 10 1 2 3 4 5 6 7 8 9 10
C program to print numbers from 1 to N using while loop
#include <stdio.h> int main() { int counter, N; printf("Enter a Positive Number\n"); scanf("%d", &N); printf("Printing Numbers form 1 to %d\n", N); counter = 1; while(counter <= N) { printf("%d \n", counter); counter++; } return 0; }
Output
Enter a Positive Number 7 Printing Numbers form 1 to 7 1 2 3 4 5 6 7
C program to print numbers from 1 to N using do while loop
#include <stdio.h> int main() { int counter, N; printf("Enter a Positive Number\n"); scanf("%d", &N); printf("Printing Numbers form 1 to %d\n", N); counter = 1; do { printf("%d \n", counter); counter++; } while(counter <= N); return 0; }
Output
Enter a Positive Number 5 Printing Numbers form 1 to 5 1 2 3 4 5
