How to find and replace all occurrences of a substring in a string?

Question

I need to search a string and edit the formatting of it.

So far I can replace the first occurrence of the string, but I am unable to do so with the next occurrences

Answer 1

try the following

const std::string s = "*A";
const std::string t = "*A\n";

std::string::size_type n = 0;
while ( ( n = chartDataString.find( s, n ) ) != std::string::npos )
{
    chartDataString.replace( n, s.size(), t );
    n += t.size();
}
