Arrays

[Natalyias77]

I am writing a program for school that is supposed to take an array and print its contents.
I have reached out to the teacher but I don't know when I will hear back.

I keep getting errors:

Errors:

Here is my program:

// Assignment 9 - Array Homework.cpp : main project file.

#include "stdafx.h"
#include <iostream>

using namespace std;

const int ARRAY_SIZE = 5;

//int round (float x); // rounds any float to the nearest int

void print_integers(int aRay[], int size); //prints out the rounded value of every element of the array


int main()
{

int listA[ARRAY_SIZE] = {0};

cout << "List A elements are: ";
print_integers(listA, ARRAY_SIZE);
cout << endl;

system ("pause");

return 0;
}

You have to write the function print_integers.

Here's something to get you started:

print_integers(int aRay[], int size)
{
   // you write code here to print the array
}

Thank you. This is my first time with arrays and functions. The book I am using was not clear on calling an array as a function.

So I have updated my code but I can't get the function to print. It will call the function, but not print out my array.

I just want to work on this piece then I will work on rounding.

Thoughts?

Plus how do I comment out my code?


void print_integers(int aRay[], int size)
{
int index;

for(index = 0; index < size; index++)
cout << "Rounded value of every element: " << aRay[index] << " " ;
}

What kind of truoble do you get? compiler messages?

void print_integers(int aRay[], int size)
{
int index;

for(index = 0; index < size; index++){
cout << "Rounded value of every element: " << aRay[index] << " " ;}
}

I think you were missing a couple of {}, but I´m not sure.
To comment a code, use //comment comment comment...(to the end of line)

or /*comment comment comment*/

Try posting your code using the code format button, at the right of the text input window.

So after working on this all day this is what I came up with.
I have gotten closer to the end result but not quite yet there.

What I now need to do is to call function round . The code for this function is supposed to take the array of float (I know I have it all as int right now) and round it off, returning the value to the nearest integer. No C++ libraries.

But so far this is what I have. It runs as I need it to. Any ideas on how to code to round off without C++ libraries?

Thanks for the hint on posting code :-)

int round (int x); // rounds any float to the nearest int
void print_integers(int aRay[], int size); //prints out the rounded value of every element of the array


int main()
{
	int sales[10];
	int index;

	print_integers(sales, index);

	system ("pause");

return 0;
}

void print_integers(int aRay[], int size)
{

	//Reads data into the array
	int list[10];
	int bulk;
	for (bulk = 0; bulk < 10; bulk++) 
	{	
	cout << "Enter a number:";
	cin >> list[bulk];
	cout << endl;
	}

	// Call to function round
	int z;
	round(z);


	// prints out what number was entered	
	int i;
	for (i = 0; i < 10; i++)
	{
	cout << "Number entered: " << list[i];
	cout << endl;
	}


}

int round (int x)
{
	cout << "Calling Round!!" << endl;

	//add code to round an element

	return x;

}

Add an amount to the float that will make the float be the right value when it is trunkated:

int floatToInt(float in)
{
  return (int)(in + 0.5f); 
}
