    Use sprintf( ).

    #include <cstdio>
    #include <cstdlib>
    int main( void ) {
        char *aString = "Hello";
        char buffer[ 256 ];
        sprintf( buffer, "test %s", aString );
        system( buffer );

    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
