Question
Consider the code fragment below: Code Listing 2.1 int row[]={0,0,0}; int col[]={0,0,0}; int diag[]={0,0}; int mask[]= { 1, 0, 3, 0, 2, 2, 3, 2, -1}; int i,j; const int DIM = 3; for (i=0; i < DIM; i++) { for(j=0; j < DIM; j++) { row[i] = row[i] + mask[i*DIM + j]; col[j] = col[j] + mask[i*DIM + j]; if (i == j) diag[0] = diag[0] + mask[i*DIM + j]; if (i + j == DIM - 1) diag[1] = diag[1] + mask[i*DIM + j]; } } (a) What would the contents of row be after the Code Listing 2.1 is executed? (b) What would the contents of col be after the Code Listing 2.1 is executed? (c) What would the contents of diag be after the Code Listing 2.1 is executed?
Explanation / Answer
Please rate it: row[]={0,0,0}; int col[]={0,0,0}; int diag[]={0,0}; int mask[]= { 1, 0, 3, 0, 2, 2, 3, 2, -1}; int i,j; const int DIM = 3; for (i=0; i
