//In this assignment, we wirte code to sum up the values of the first n bytes in a memory block //that is allocated for n unsigned integers. //The memory allocation occurs in the main function //We need to implement the function sum_n_bytes //This function returns the sum of the values of the first n bytes that is pointed by //the pointer p

#include #include

//Implement the following function //The function sum_n_bytes returns the sum of the values of the first n bytes in the memory block//pointed by the pointer p unsigned sum_n_bytes(unsigned *p, int n) { //fill in your code below //Note that the sum should be an unsigned integer //This should has some ramifications on your code //Only a few lines of code expected }

//Note how we use the command line arguments int main(int argc, char *argv[]) { if(argc != 2) { printf("Usage: %s n ", argv[0]); exit(-1); } int n = atoi(argv[1]); //allocate memory for n unsigned integers unsigned *p = calloc(n, sizeof(unsigned)); //Assign values to these unsigned integers in a certain pattern int i; for(i=0; i< n; i++) { p[i] = 1 << (i % 32); } //print out the sum of the first n bytes printf("%d ", sum_n_bytes(p, n)); //do not forget to free p free(p); return 0; }
