Shifting text

Applications Programming

I have the following functions which shifts the text by 4 and 8 characters. How can I pass an integer for the shift so that the text is shifted accordingly?

void prValue4_vd (
  FILE*  stream,           // name of output stream
  const char*  value,      // value associated with argument action key
  const char*  desc ) {    // description

    const char* frValue4_vd;
    frValue4_vd = "    \e[1;32m%s\e[0;37m    %s\e[0m\n";
    fprintf ( stream, frValue4_vd, value, desc );

}

void prValue8_vd (
  FILE*  stream,           // name of output stream
  const char*  value,      // value associated with argument action key
  const char*  desc ) {    // description

    const char* frValue8_vd;
    frValue8_vd = "        \e[1;32m%s\e[0;37m    %s\e[0m\n";
    fprintf ( stream, frValue8_vd, value, desc );

}

Done

void prDfltValue8_vd (
  FILE*  stream,           // name of output stream
  string  value,      // value associated with argument action key
  string  desc,       // description
  int  shift ) {           // shift

    string shft(shift,' ');
    string frValue8_vd = shft + "\e[42;1m \e[0m \e[1;32m%s\e[0;37m    %s\e[0m\n";
    const char* format = frValue8_vd.c_str();
    const char* val = value.c_str();
    const char* dsc = desc.c_str();
    fprintf ( stream, format, val, dsc );

}

Here is how it can be done...

const char* frValue4_vd;
int shift = 4;
frValue4_vd = "%*s\e[1;32m%s\e[0;37m    %s\e[0m\n";
fprintf ( stream, frValue4_vd, shift, " ", value, desc );

where "shift" can be passed in as a function argument...
