I need this program to display the output (" 111 56 "). Whats the problem with it?
thanks!Code:#include <iostream.h> class Exchg { public: void exchange (int& a, int& b) { int temp = a; a = b; b = temp;}}; main () { int num1 = 56; int num2 = 111; cout << "the two numbers: " << num1 << "," << num2 << "..." << endl; exchange (num1, num2); cout << "... are now exchanged: " << num1 << "," << num2 << endl; }
