I\'m using std::string and need to left pad them to a given width. What is the recommended way to do this in C++?

Sample input:

Answer 1

I was looking the topic because Im developing VCL; Anyway making a function wasn't not so hard.

void addWhiteSpcs(string &str, int maxLength) {
    int i, length;

    length = str.length();
    for(i=length; i

In both cases it will add to the right 10 blank spaces. I Recomend to use monospace fonts like courier or consolas for a correct format.

This is what happens when you're not using monospace font
johnny____
cash______

// using monospace font the output will be
johnny____
cash______

Both cases have the same length.
