this function in c++ works as follows -> system("c:\example.exe");
but i wish to pass a string instead of writing it -> system(myString);
where myString has paths that can be changed on running time.

how do i declare the string or what can i do to use a standar (std::string myString="hello") one in 'system' function?

It has to be a character array (or converted to one)...

(Toggle Plain Text)

#include <iostream>

int main(int argc, char *argv[]) {
    char sys[1024] = "C:\\Program Files\\Internet Explorer\\iexplore.exe "; 
    char input[256];
    std::cout << "What website would you like to view? ";
    std::cin >> input;
    strcat(sys, input);
    system(sys);
    return 0;
}
