Question

Given the C++ program, determine the output:

#include
using namespace std;
int main() {
int i, j;
int *pi, *pj;
i = 5;
j = i;
pi = &i;
pj = &j;
*pj = 4;
cout << i << " " << j << " " << *pi << " " << *pj << endl;
return 0;
}

Answer 1

The output of the given C++ program will be '5 4 5 4', representing the separate values of the variables i, j, and the dereferenced values of pointers pi and pj.

Step-by-step explanation:

The given C++ program initializes two integer variables i and j, and two pointer variables pi and pj. Initially, i is set to 5, and j is assigned the value of i. Next, pi is assigned the address of i, and pj is assigned the address of j. When *pj is set to 4, it changes the value of j but not i. Therefore, the output of the program will be '5 4 5 4', corresponding to the values of i, j, the value pointed to by pi (which is i), and the value pointed to by pj (which is j) respectively.
