There are two different functions to get the absolute value of an integer

int abs(int) and of a double value double fabs(double):
cout << "The absolute value  of -10 is " << abs(-10) << endl;
cout << "The absolute value of 12.71 is " << fabs(12.71) << endl;
cout << "The absolute value  of -88 is " << abs(-88) << endl;
cout << "The absolute value  of 4 is " << abs(4) << endl;

cout << "C++ Programming Language | Happy Codings :)";
