Q305.

How do you allocate a matrix using a single pointer in C? (M and N are the number of rows and columns respectively)

int *arr = malloc(M * N * sizeof(int));

int *arr = (int *)malloc(M * N * sizeof(int));

int *arr = (int *)malloc(M + N * sizeof(int));

int *arr = (int *)malloc(M * N * sizeof(arr));

Discuss

Answer: (b).int *arr = (int *)malloc(M * N * sizeof(int));
