Memory Dump error on runtime

What is the problem in this code ? It shows memory dump error in runtime

#include<iostream>
using namespace std ;
int main()
{
    int A[3][4] = {{3, 1, 8, 11}, {4, 12, 9, 10}, {7, 5, 2, 6}};
    int **p = A;
    P[1][2] = 99;
    cout<<A[1][2] ;
}
Solution

  • Change your int **p = A[0][0] to int *p = &A[0][0]. In the next line, write the following *p = *((int*)p + 1 * NUM_OF_COLUMNS + 2) = 99;, where NUM_OF_COLUMNS is the number 4, instead of the P[1][2] = 99;. Correct the spelling of main as well as uppercase/lowercase of variables. Also add a return 0; at the end since you have an int main() and not a void.
