Question

Write a complete C++ program that is made of functions main() and rShift(). The rShift() function must be a function without return with 6 parameters. rShift() should do following.

• Shift the first 4 formal parameters' value one place to right circularly and send the updated values out to the caller function, i.e. main. Furthermore, after calling this function with first 4 actual parameters, say a1, a2, a3, a4, and these actual parameters should shift their value one place to right circularly as well. That is, a1 takes a2's value, a2 takes a3's value, a3 takes a4's value, and a4 takes a1's value.

• Assuming that first 4 formal parameters of rShift are n1, n2, n3, and n4, rShift should calculate maximum and average of n1, n2, n3, and n4, and send results back to caller function, i.e. main.

The main() function should do following:

1. Read four integers from the user with proper prompt and save them to four local variables.

2. Call the rShift() function with 6 actual parameters.

3. Receive all results, i.e. four shifted integers, plus maximum and average from rShift(). Then print these numbers with proper prompt text.

4. Note:

   1. No input and output with the user inside rShift() function. All input and output should be strictly limited inside main() function.

   2. Both statistics must be calculated with basic C++ flow control statements, and cannot be implemented by calling library functions such as max().

Answer 1

Here is your answer.. Code in C++

#include<iostream>
using namespace std;
//rShift() function be a function without return with 6 parameters
void rShift(int& n1,int& n2,int& n3,int& n4,int& n5,float& n6)
{
//Shifting value
int temp=n4;
n4=n3;
n3=n2;
n2=n1;
n1=temp;
//Computing maximum value
if(n1> n2 && n1>n3 && n1>n4)
n5=n1;
else if(n2> n1 && n2>n3 && n2>n4)
n5=n2;
else if(n3> n1 && n3>n2 && n3>n4)
n5=n3;
else
n5=n4;
//Computing Average value
n6=(n1+n2+n3+n4)/4.0;
}
int main()
{
//n1 n2 n3 n4 are integer will be entered by the user n5 is for max value
int n1,n2,n3,n4,n5;
float n6;//to store average of 4 integer
cout<<"**********************Enter 4 integer value*********"<<endl;
cout<<"Enter value of n1:";
cin>>n1;
cout<<"Enter value of n2:";
cin>>n2;
cout<<"Enter value of n3:";
cin>>n3;
cout<<"Enter value of n4:";
cin>>n4;
rShift(n1,n2,n3,n4,n5,n6);//rShift function call
cout<<"After rShift value of n1:" <<n1<<endl;
cout<<"After rShift value of n2:" <<n2<<endl;
cout<<"After rShift value of n3:" <<n3<<endl;
cout<<"After rShift value of n4:" <<n4<<endl;
cout<<"Max of 4 integer value:"<<n5<<endl;
cout<<"Average of 4 integer value:"<<n6<<endl;
return 0;
}
//Output
