#include#include int main() { CString myString = "Hello, world!"; int length = myString.GetLength(); std::cout << length << std::endl; // output: 13 return 0; }
#includeIn this example, we create a new std::string object with the value "Hello, world!" and use the "length" function to get the length of the string, which is also 13. Package/library: Standard Template Library (STL) In conclusion, the "CString length" function is part of the ATL library, while the "string length" function is part of the STL library.#include int main() { std::string myString = "Hello, world!"; int length = myString.length(); std::cout << length << std::endl; // output: 13 return 0; }
