Give the values of the variables at the indicated points during the execution of the program in Listing 3 or indicate the value of the variable is indeterminate. Each variable is prefix with its scope, the function in which it is defined. Listing 3: Code Segment 1 #include 2 3 using namespace std; 4 5 void mystery (int& a, int b, int& c) 6 { 7 a = a +b; 8 b= a - b; 9 cra-b; 10) 12 13 int main() 14 15 int a=3, b=2, c=1; 16 mystery(b,a,c); 17 return 0; 18) Give values for the variables main::a, main::b, main.c, mystery::a, mystery::b and mystery::c at the specified times during the execution of the program or indicate that the value of the variable is indeterminate by typing 8e88.
