How to convert a command-line argument to int?

Question

I need to get an argument and convert it to an int. Here is my code so far:

#include 


using namespace std;
int main(int argc,int argvx[]) {         


        

Answer 1

Like that we can do....

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

    int a, b, c;
    *// Converting string type to integer type
    // using function "atoi( argument)"* 

    a = atoi(argv[1]);     
    b = atoi(argv[2]);
    c = atoi(argv[3]);

 }
