Program to Check Prime Number #include <stdio.h> int main() { int n, i, flag = 0; printf("Enter a positive integer: "); scanf("%d", &n); // 0 and 1 are not prime numbers // change flag to 1 for non-prime number if (n == 0 || n == 1) flag = 1; for (i = 2...
Write a program in C to check whether a number is a prime number or not using the function. Pictorial Presentation: Sample Solution: C Code: #include<stdio.h>intPrimeOrNot(int);intmain(){intn1,prime;printf("\n\n Function : check whether a number is prime number or not :\n");print...
If the user enters the larger number first, the above program doesn't work as intended. You can solve this issue by swapping the numbers. Display Prime Numbers when Larger Number is Entered first #include <stdio.h> int main() { int low, high, i, flag, temp; printf("Enter two numbers...
In this C program, we are going to learn how can we check and delete prime numbers from an array? We are declaring an array with some prime and non prime numbers and deleting prime numbers and then printing array elements with the numbers which are not prime. Submitted by IncludeHelp, ...
