c++ string erase all occurrences

To erase all occurrences of a specific substring from a C++ string, you can use the std::string::erase function in a loop. Here are the steps:

1. Start by defining the main string and the substring to be removed.

2. Use a while loop to continue erasing the substring until it no longer exists in the main string.

3. Inside the loop, find the position of the substring using std::string::find.

4. If the substring is found, use std::string::erase to remove the substring from the main string at the found position.

5. Continue the loop until the substring is no longer found in the main string.
