Question

In C, how would you take in 3 inputs via the command line then convert the strings into inputs and make sure they are integers?

Answer 1

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
    if(argc!=4) {
        printf("Please input three command line arguments\n");
        return 0;
    }
    int n1 = atoi(argv[1]);  
    int n2 = atoi(argv[2]);  
    int n3 = atoi(argv[3]);  
    printf("Three command line numbers are: %d %d %d\n",n1,n2,n3);
    return 0;
 }
