You need to format a string containing those values. You could use sprintf, or std::format - depending on which version of C++ you're using

Just an example of course:

char a = 'a';
char b = 'b';
char c = 'c';
auto strabc = std::format( "This is the {}{}{}", a, b, c ); // results in strabc being: "This is the abc"
system( strabc.c_str() );
