std::string str = "hello world"; str.remove(3, 2); // removes 2 characters starting from index 3 std::cout << str; // outputs "heo world"
std::string str = "hello world"; auto it = str.begin() + 3; str.erase(it, it + 2); // removes 2 characters starting from the iterator std::cout << str; // outputs "heo world"In both examples, the remove function is used to delete two characters from the string starting at index 3. The first example uses the remove member function directly, while the second example uses the erase member function with iterators. Package library: The string remove function is part of the C++ standard library and is included in the
