1 Last 5 Characters of "Hello World" String

In this example,

We create a string named str1 with a string value of "Hello World".
We then use str1.substr(str1.length() - 5) to get the last 5 characters.
Finally, we print the last 5 characters.

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str1 = "Hello World";
    std::string last5Chars = str1.substr(str1.length() - 5);
    std::cout << "Last 5 characters of the string are: " << last5Chars << std::endl;
    return 0;
}

Output

Last 5 characters of the string are: World

2 Last 3 Characters of "apple" String

We create a string named str2 with a string value of "apple".

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str2 = "apple";
    std::string last3Chars = str2.substr(str2.length() - 3);
    std::cout << "Last 3 characters of the string are: " << last3Chars << std::endl;
