Okay so the program is working, however I suppose it's too slow for the submissions liking. What would you do to make it faster? Use a class, inline functions, etc.

include <cstdio>

int isPrime(long num); int isPalindrome(unsigned long orig);

int main(int argc, const char * argv[]) {

int n = 0;
const int LIMIT = 1000000;
scanf("%d", &n);
int m = n;

    while(n <= LIMIT) {
    if(isPrime(m) && isPalindrome(m)){
        printf("%d \n", m);
        break;

    }
    else {
        m++;
    }

}

return 0;

}

int isPrime(long num) { if (num < 2) return 0;

if (num > 2 && (num % 2) == 0)
    return 0;

for(int i = 2; i < num; i++ )
{
    if ( (num % i) == 0)
    {

        return 0;
    }
}


return 1;

}

int isPalindrome(unsigned long orig) { unsigned long reversed = 0, n = orig;

while (n > 0)
{
    reversed = reversed * 10 + n % 10;
    n /= 10;
}

return orig == reversed;

}
