#includeIn this example, we create two QCString objects called "str1" and "str2" and then compare them using the "compare()" method. The result of the comparison is stored in the integer variable "result", which we then use to print a message indicating whether the strings are equal or not. The QCString class is part of the Qt Core library, which provides a range of reusable components and functionality for C++ development.#include int main() { QCString str1 = "Hello, world!"; QCString str2 = "Hello, Qt!"; int result = str1.compare(str2); if (result == 0) { std::cout << "The strings are equal." << std::endl; } else { std::cout << "The strings are not equal." << std::endl; } return 0; }
