C Program to Print Prime Numbers Between 1 to n using For Loop
Write a Program to Print Prime Numbers Between 1 to n using For Loop
#include <stdio.h> #include <stdbool.h> bool isPrime(int n) { if(n == 1 || n ==0) return false; int i = 2; for(i = 2; i < n; i++) { if(n % i == 0) { return false; } } return true; } int main() { int n, i; printf("Enter the number :--> "); scanf("%d", &n); printf("Prime numbers between 1 to %d :--> ", n); for(i = 1; i < n; i++) { if(isPrime(i)) { printf("%d ",i); } } return 0; }
Output:
Enter the number :--> 25
The prime numbers are :2 3 5 7 11 13 17 19 23
