#include <iostream> // Use iostream for C++ input/output using namespace std; // This allows us to use cout and endl without std:: prefix int main() { int a = 5; int b = 5; // a will increment first int c = ++a + 10; // b is used first int d = b++ + 10; // Output using cout cout << "Value of c: " << c << endl; // a is incremented first, then 10 is added cout << "Value of d: " << d << endl; // b is used first, then incremented cout << "Final value of b: " << b << endl; // b is now incremented return 0; } |
