Question

A) Fix any errors to get the following program to run in your environment.              

B) Document each line of code with comments and describe any changes you had to make to the original code to get it to work.

C) Write a summary of what your final version of the program does.

You may also add white space or reorder the code to suit your own style as long as the intended function does not change.

Program 3

#include <iostream>
using namespace std;

void m(int, int []);
void p(const int list[], int arraySize)
{
    list[0] = 100;
}

int main()
{
int x = 1;
int y[10];
y[0] = 1;

m(x, y);

cout << "x is " << x << endl;
cout << "y[0] is " << y[0] << endl;

return 0;
}

void m(int number, int numbers[])
{
number = 1001;
numbers[0] = 5555;
}

Answer 1

Answer A and B)

Program code to copy:

// header file
#include <iostream>
using namespace std;

// Function declaration for m()
void m(int, int []);
// function that sets the first element of list as 100
void p(int list[], int arraySize)
{
list[0] = 100;
}

// main function
int main()
{
int x = 1; // defining int variable x
int y[10]; // declaring int array y[] of size 10
y[0] = 1; // setting first element of y as 1.
// calling function m with parameters x and y
// this will set y[0] = 5555
m(x, y);
// displaying the results after function call m(x,y)
cout << "x is " << x << endl;
cout << "y[0] is " << y[0] << endl;
// exit
return 0;
}

// function that sets the first element
// of integer array numbers[0] = 5555
void m(int number, int numbers[])
{
number = 1001;
numbers[0] = 5555;
}

Sample output:

x is 1 y[0] is 5555

Answer C)

Summary of final version of the program:

First, integer variable x is declared and is set to 1. Next, integer array y[ ] is declared & the first element of the array y[ ] is set to be 1. Next, function m(x,y) is called which sets the first element of the array y[ ] to be 5555. Finally, the values of x and y[0] are displayed which are 1 and 5555 respectively.
