Answer 1

boost string algorithms

Example:

string str1="Hello Dolly, Hello World!"
replace_first(str1, "Dolly", "Jane"); // str1 == "Hello Jane, Hello World!"
replace_last(str1, "Hello", "Goodbye"); // str1 == "Hello Jane, Goodbye World!"
erase_all(str1, " "); // str1 == "HelloJane,GoodbyeWorld!"
erase_head(str1, 6); // str1 == "Jane,GoodbyeWorld!"

Download boost from here

Documentation of this particular library is here (page 5 is about replace algorithms)
