Prime Numbers in C

In this blog, I am going to explain how to check a number for whether it is a prime number or not.

Introduction

• In this article, I am explaining how to check and print a prime number. 

Software Requirements

• Turbo C++ or C.

Programming 

#include < stdio.h >
int main()
{
    int n, i = 3, count, c;
    printf("Enter the number of prime numbers required\n");
    scanf("%d", & n);
    if (n >= 1)
    {
        printf("First %d prime numbers are :\n", n);
        printf("2\n");
    }
    for (count = 2; count <= n;)
    {
        for (c = 2; c <= i - 1; c++)
        {
            if (i % c == 0) break;
        }
        if (c == i)
        {
            printf("%d\n", i);
            count++;
        }
        i++;
    }
    return 0;
}

Explanation

• In the above program, the prime number can be displayed in simple manner.
