    Question using windows system()

    I am kinda new to C++ and I would like to know if it is possible to pass on the values of variables to the system() functions?

    example:
    Code:
    void main()
    {
        char tag[1];
    
        cin >> tag;
    
        system("attrib tag");
    }
    this one doesn't work. Its just to give an example of what I want to do... I want to pass the value stored in tag as apart of a system() argument. Is it possible? if yes, how do I do it?

    You need to build the string to pass to system, using sprintf or stringstreams or something similar.

    Try this.
    Code:
    #include <cstdlib>
    #include <iostream>
    #include <string>
    
    int main()
    {
    	std::string tag;
    
    	std::cout << "Enter tag: ";
    	std::cin >> tag;
    
    	system(std::string("attrib " + tag).c_str());
    
    	return 0;
    }
