Question

This following program is supposed print 80 40 5, but it does not. Find all the bugs and rewrite the entire corrected
version of the program. Note that cout<<”80 40 5”; is not a correct fix, you may not use a for-loop or the variable
arr. Make as small changes to the original code as possible, some reordering may be necessary, but replacing entire
lines of code is not acceptable.
int main(){
intarr[3] = { 5, 10, 15 };
int* ptr = arr;
ptr = 5; // set arr[0] to 5
*ptr + 1 = 40; // set arr[1] to 40
ptr += 2;
ptr[0] = 80; // set arr[2] to 80
while (ptr >= arr) {
ptr--;
cout << ' ' << ptr; // print values
}
cout << endl;
}

Answer 1

Solution:

//code after some corrections

#include <iostream>

using namespace std;

int main(){

int arr[3] = { 5, 10, 15 };//array initialization

int* ptr = arr;

*ptr += 75; // add arr[0] to 75

*(ptr+1) += 30;//add arr[1] to 30

arr[2] -= 10;//substract arr[2] to 10

while (ptr < arr+3) {//while loop

cout<<*(ptr)<<" ";

ptr++;

}

cout << endl;

return 0;

}

Thank you, Have a great day:-)
