What are some common string operations in C++?

In C++, common string operations include concatenation, substring extraction, and searching for characters or substrings.

Can you show me how to concatenate two strings?

Sure! You can concatenate two strings using the '+' operator or the 'append()' method. For example:

std::string str1 = "Hello, ";
std::string str2 = "World!";
std::string result = str1 + str2; // result is "Hello, World!"

What about finding a substring within a string?

You can use the 'find()' method to locate a substring. For example:

std::string str = "Hello, World!";
size_t pos = str.find("World"); // pos will be 7
