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

In case boost is available, you can use the following:

std::string origStr = "this string has *A and then another *A";
std::string subStringToRemove = "*A";
std::string subStringToReplace = "[A]";

boost::replace_all(origStr , subStringToRemove , subStringToReplace);

To perform the modification on the original string, OR

std::string result = boost::replace_all_copy(origStr , subStringToRemove , subStringToReplace);

To perform the modifications without modifying the original string.
