Answer

To concatenate two strings in C++, you can use the `+` operator or the `append()` function.

✐ Examples

1 Concatenate "Hello" and "World"

In this example,

We define two variables of type `std::string` named str1 and str2 with values "Hello" and "World" respectively.
We then concatenate str2 to str1 using the `+` operator and store the result in a variable named result.
Finally, we print the concatenated string result to the console.

C++ Program

#include <iostream>
#include <string>

int main() {
    std::string str1 = "Hello";
    std::string str2 = "World";
    std::string result = str1 + str2;
    std::cout << result;
    return 0;
}
