Getting input in system() function (Mac)

#include <iostream>
using namespace std;

int main() {

    short int enterVal;
    cout << "enter a number to say: " << endl;
    cin >> enterVal;
    system("say "%d"") << enterVal;

    return 0;
}

Is what I am currently trying. I want the user to enter a number and the system() function says it basically. The code above has an error which says " 'd' was not declared in this scope ". Thanks in advance.

Solution

  • You must format the string manually.

    #include <iostream>
#include <sstream>
using namespace std;

int main()
{
    short int enterVal;
    cin >> enterVal;

    stringstream ss;
    ss << "say \"" << enterval << "\"";
    system(ss.str().c_str());
}
