How to replace all occurrences of a character in string?

E.g, I have a string, "Hello World" and I want to replace all the "l"s with "1"s. How would I do this? I am new to c++. Most of my background is in Python in which you could just use the .replace method.

Use std::replace.

#include <string> #include <algorithm> #include <iostream> int main() { std::string str = "Hello World"; std::replace(str.begin(),str.end(),'l','1'); std::cout << str; //He11o Wor1d }
