passing variables to system

[joshky]

I am wondering how I can pass a variable to the system function. i.e.:

int x=3;
char y='B';
system("color" x y);

Obviously the code doesn't work like that, but you get the point.

system function's signature is int system(const char* command);. So in short, it does not take second argument.

how about:
string a;
system(a.c_str());

In this case, why not just use SetConsoleTextAttribute() ?

If its possible to make x and y strings...

system(("color "+x+y).c_str());

You can use sprintf ( C style ) http://www.cplusplus.com/reference/clibrary/cstdio/sprintf/
Or stringstreams:

stringstream ss;
ss << "color " << x << y;
system( ss.str().c_str() );

BTW, don't use 'system' http://www.cplusplus.com/forum/articles/11153/
