What is the purpose of the following code snippet?  #include struct point { int x; int y; }; struct point doSomething(struct point p1, struct point p2) { struct point result; result.x = p1.x + p2.x; result.y = p1.y + p2.y; return result; } int main() { struct point p1 = {1, 2}; struct point p2 = {3, 4}; struct point sum = doSomething(p1, p2); printf(“%d %d\n”, sum.x, sum.y); return 0; }
