I have to create a 5x4 array int A[5][4] = { 4,1,6,9,1,2,3,4,7,6,5,4,3,8,3,9,1,5,7,3 }; and add all the elements of the array. I tried

for (i = 0; i <= 4; i++) {

for (j = 0; j <=3; j++) {

sum += A[i][j];

}

}

cout<<sum;

Using this coding the sum is 107 (actual sum is 91)

Also, I tried

for (i = 0; i <= 4; i++) {

for (j = 0; j <=3; j++) {

sum +=(i+j);

}

}

cout << sum;

The sum is 86 ( also wrong). What code to use to find the total sum of elements of a two dimensional array?
