1. Problem 1: This is a brief exercise. (The labs will require comfort and fluency in C.) Below is a snippet of code: void opi(int a, int b) { a = a + b; void op2(int* a, int* b) { *a = *a + *b; 1; int main() { int a = 1, b = 1, C = 1, d = op1(a, b); op2(&c, &d); return 0; What are the values of a, b, c, and d right before the program exits? Since the purpose of this exercise is to build your skills, you should do this problem without compiling and running the program
