Question

USE THE TABLE AND OUTPUT TECHNIQUE FOR THIS 8 POINT PROBLEM What is the output from the following SEGMENT: note TYPES OF PARAMETERS AND VARIABLE SCOPES Hint: A table is not necessary but it may help you get the output and its order int (4), C(2): HINT THESE ARE GLOBAL int TestMe(int &Y, int Z) / PROTOTYPE FOR THE FUNCTION int main 0 int A BW: A = 4: B-3 W = Test Me A, B) MI CALL TO THE FUNCTION cout<<"-<A<"B="<B<<endl; If these final outputs are the most important part cout << "X="<< X<<"C"<<<endl cout << "W="W<< endl; ) int Test Me (int & Y. int Z) // THE FUN FUNCTION X=X+2; Y-C+2 return IV: (5 pts) consider following program segment show the memory snapshot of each member of the array, le. What are the values of each, specify each member by name and index: illustrative example array A member A[0]-9 use? if no value

Answer 1

Answer

now X and C are globale variabales

And X=4, C=2

Now A ,B, and W are local varibales

A=4, B=3

Now in test function first parameter is passed by references

At starting values of all the variables are:

X   C   A    B
4   2   4   3

now calling test function with A and B be sure A passed as references

so In function Y=4 and Z=3

Now X = X + Z
So   X = 4 + 3
   X = 7
  
Now Y = C + Z
so Y = 2 + 3
   Y = 5

And return Z so return 3

Now here Y passed as references So A's value chage to 5
B remains same 3
W = 3

So after Test function

X   C   A    B W
7 2 5 3 3

So output is

A = 5 B = 3
X = 7 C = 2
W = 3
