9. (20 pts.) Pointers onsider the following lines of code: int al3]I4] K10, 20, 30, 40 (5, 10, 15, 20, printf("The sum is %d ", sumit((int *)a, 3, 4)); , write the function the number of rows and cols of the 2D array, respectively, and returns the sumit that receives a pointer to a 3 x 4- 2D array of integers, and 2 integers representing sum of the values in this array. You brackets use ingle loop (which type is your choice) AND you CANNOT use any indesing, Le. can'tuse square (I 1): 10. (20 pts.) The strcpy function receives two pointers to strings of characters: a destination (thought to be an array of char but could be allocated memory) and a source. strcpy copies the source into the destination Also, it returns a pointer to the destination. The destination must contain enough bytes to hold the entire source string plus the null terminating character (strcpy does not check for this!). This is a function of which you should already be familiar. Using only pointers (as the actual function does), write strcpy here: (strcpy(dest, src)
