Hi, i have a problem with my array. i got a 2d array. array[49][14]. i need to find out the value of something like this: array[0][j]*0+array[1][j]*1+array[2][j]*2+...+ array[48][j]*48, where the value of j goes form 0 to 13 (that is sum of each elements in the array times the x coordinate of the array) . i write a code using for loop. but i keep getting 0. i think my code is wrong. would anyone please take a look at it? thanks!
sum_zx = 0; for (i=0; i < 49; ++i) for (j=0; j < 14; ++j) sum_zx = sum_zx + j*array[i][j];
