C Program to display the first 10 prime numbers using function - IProgramX

Q. Write a function isPrime, which accepts an integer as parameter and returns 1 if the number is prime and 0 otherwise. Use this function in main to display the first 10 prime numbers

Program

#include <stdio.h>
int isPrime(int n);
int main()
{
    int  i=2,j=0 ,flag;
while(j!=10)
    {
        flag = isPrime(i);
        if(flag == 1)
        {
            j++;
            printf("%d ",i);
}
i++;  
    }
    return 0;
}
int isPrime(int n)
{
    int j, flag = 1;
    for(j=2; j <= n/2; ++j)
    {
        if (n%j == 0)
        {
            flag =0;
            break;
        }
    }
    return flag;
}

Output:

2 3 5 7 11 13 17 19 23 29
