Se puede declarar un valor booleano de una variable como:
bool GotThePassingGrade = true;Later in the program, for a student who got a failing grade,you can assign the other value, like this GotThePassingGrade = false;Here is an example: #include <iostream> using namespace std;//--------------------------------------------------------------------------- int main(int argc, char* argv[]) { bool MachineIsWorking = true;cout << "Since this machine is working, its value is " << MachineIsWorking << endl;MachineIsWorking = false; cout << "The machine has stopped operating. " << "Now its value is " << MachineIsWorking << endl;return 0; } //--------------------------------------------------------------------------- |
