1 Remove 'l' from "Hello World"

In this example,

We create a string variable str with a value of "Hello World".
We use the erase method of the std::string class to remove all occurrences of 'l' from str.
Finally, we print the modified string str.

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str = "Hello World";
    str.erase(std::remove(str.begin(), str.end(), 'l'), str.end());
    std::cout << "Modified string: " << str;
    return 0;
}

#include <string>

int main() {
    std::string str = "apple";
    str.erase(std::remove(str.begin(), str.end(), 'a'), str.end());
