Question

4. Consider the following (almost) complete program: 4includeciostream> using namespace std: la)prototypes here. int main () const int size 6 int alsize] 15, 2, 3, 1, 13, 8): int p pma+1 show (a, size) mystery (a, size); show (a, aize) cout<<a [2]+a(51<<endl; cout<<(a+2)-3<<endl: cout<<tp+ a<<endl; cout<<at5<cendl void show (int all, int n) 17 (b) define show void mystery (int all, int n) int temp Eor (int i-0 i<n/2 i++) temp aij alil-aln-i-117 a [n-i-11 temp a) Write prototypes for the functions show () and mystery (). b) Write a function definition for show () that wil1 print out the contents of the array separated by spaces. c) After completing the program by answering to questions a) and bi, trace the output. The address value of a is 0044FB44 (a-0044FB44)

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new c++ program with name "main.cpp" is created, which contains following code.

main.cpp :

#include <iostream>
using namespace std;
//(a) prototypes here
void show(int a[],int);
void mystery(int a[],int);
int main()
{
const int size=6;
int a[size]={5,2,3,1,13,8};
int *p;
p=a+1;
show(a,size);//show method call
mystery(a,size);//mystery method call
show(a,size);//show method call
cout<<a[2]+a[5]<<endl;
cout<<(*a+2)-3<<endl;
cout<<*p+*a<<endl;
cout<<a+5<<endl;

return 0;
}
//show function defination
void show(int a[],int size)
{
//(b) define show
for(int i=0;i<size;i++)
{
cout<<a[i]<<" ";//print each array element separated by space
}
cout<<endl;//used for new line
}
//mystery function defination
void mystery(int a[],int n)
{
int temp;
for(int i=0;i<n/2;i++)
{
temp=a[i];
a[i]=a[n-i-1];
a[n-i-1]=temp;
}
}

======================================================

Output : Compile and Run above program to get the screen as shown below

Screen 1 :main.cpp

input 5 2 3 1 138 8 13 1 3 2 5 6 7 21 Ox7ffc0989c624 . Program finished with exit code 0 Press ENTER to exit console
