Consider the following C program: #include int main() { int a; int arr[5] = {30,50,10}; int *ptr; ptr = &arr[0] + 1; a = *ptr; (*ptr)++; ptr++; printf("%d", a + (*ptr) + arr[1]); return 0; } The output of the above progr...

What is the output of the following C program? #include int main() { double a [2]={20.0, 25.0}, *p, *q; p = a; q = p + 1; printf("%d,%d", (int)(q - p), (int)(*q - *p)); return 0;}
