QUESTION 1 What is the problem with the code snippet below? void cost (int price, int reps) { for (int i = 0; i < reps; i++) { cout << price; } return; int main() { cout << cost (10, 4) << endl; return 0; The function cost is invoked with the wrong parameters. The function cost uses uninitialized variables. The function cost returns void and therefore cannot be used in a cout statement. The function cost must return an integer value. QUESTION 2 What is the output of the following code snippet? #include <iostream> #include <string> using namespace std; int main() { int varl - 10%; int var2 = 2; int var3 = 20; var3 var3 (varl var2); cout << var3 << endl; return 0; 0 4 20 There will be no output due to a run-time error.
