Answer:

#include <iostream>

using namespace std;

int main() {

  int i = 2;

  double j = 3;

 

  int *p = &i;

  double *q = &j;

 

  cout << "p = " << p << ", p+1 = " << p+1 << endl;

  cout << "q = " << q << ", q+1 = " << q+1 << endl;

  return 0;

}

Explanation:

In C++, pointers are variables or data types that hold the location of another variable in memory. It is denoted by asterisks in between the data type and pointer name during declaration.

The C++ source code above defines two pointers, "p" which is an integer pointer and "q", a double. The reference of the variables i and j are assigned to p and q respectively and the out of the pointers are the location of the i and j values in memory.

Can someone please tell me what I’m doing wrong ? Please and it’s due on Thursday!!
liberstina [14]

Answer:

Sure. In Unit test 5, it's looking for 1 instead of 0. You are returning 0 instead of 1.

0 requires 1 digit to express it and should therefore return 1.

In line 6, change the 0 to a 1.
