just

int array [3], t;

to

int array [10], t;

i have this code which input 3 numbers into ascending order. i know make it 10 i just change the array size but then it is only ascending the numbers that were inputing that are under 10. how can i change it so it's any number.

#include <iostream>
#include <conio.h>

using namespace std; 

int  main ()
{   int x;
        
        int array [3], t;
        for (x=0; x<3; x++)
        {
        cout << "Enter integer number: " << endl; 
        cin >> array[x]; 
        }
        for (x=0; x<3; x++)
        {
                for (int y=0; y<2; y++)
                {
                        if(array[y]>array[y+1])
                        {
                t=array[y];
                array[y]=array[y+1];
                array[y+1]=t;
                        }
                }
        }
        cout << "The integers in ascending order are : ";
        for (x=0;x<3;x++)
        {  
           cout <<"\n";
           cout <<array[x];
           cout << "\n";
        }
     system ("pause");
        return 0;  
        }

i have this code here which inputs the numbers and then adds them. is there a cheats way i can change it so that it inputs the numbers then puts them into ascending order.

#include <iostream.h>
void getNumber(int &, int); 
void sum( int, int &); 
void output(int[ ], int, int); 
int main()
{
const int SIZE = 10;
int array[SIZE] = {0};
int total = 0;
for ( int i = 0; i < SIZE; i++)
{

getNumber(array[i], i + 1);
sum( array[i], total);
}

output(array, total, SIZE);
}void getNumber(int &num, int numCount)
{
cout << "Enter number " << numCount << ":";
cin >> num;
}
void sum(int num, int &total)
{
total += num;
}

void output(int array[ ], int total, int arraySize)
{
cout << "The sum of ";
for (int i = 0; i < arraySize; i++)
{
cout << array[i] ;

if( i < arraySize - 1)
cout << " + ";
}
cout << " is " << total << endl;
system ("pause");
}

i've fixed it now.

#include <iostream.h>

void readThreeNumbers(int &, int &, int &);
void sortThreeNumbers(int &, int &, int &);
void displayNumbers(int, int, int);

int  main()
{
int number1, number2, number3;
readThreeNumbers(number1, number2, number3);
sortThreeNumbers(number1, number2, number3);
displayNumbers(number1, number2, number3);
}
void readThreeNumbers(int &number1, int &number2, int &number3)
{
cout << "Enter three numbers, with a space between them: ";
cin >> number1 >> number2 >> number3;
}
void sortThreeNumbers(int &number1, int &number2, int &number3)
{
int temp; 
if (number1 > number2)
{
temp = number1;
number1 = number2;
number2 = temp;
}
if (number2 > number3)
{
temp = number2;
number2 = number3;
number3 = temp;
}
if (number1 > number2)
{
temp = number1;
number1 = number2;
number2 = temp;
}
}
void displayNumbers(int number1, int number2, int number3)
{
cout << "\nThe numbers sorted in ascending order are\n"
<< number1 << endl
<< number2 << endl
<< number3 << endl;
system ("pause");
}

ok this is it now

#include<iomanip>
using namespace std;


void readThreeNumbers(float number1,float number2,float number3);

i have this code that which inputs three number sort the three numbers in
ascending order then output the three numbers.

i'm getting this list of errors but i don't know how fix it.

im getting this error use of enum `ComponentTypes' without previous declaration
where do i declare it.

ok thank you

ok i understand that but where do i put it in the code.
and how do i write it before each question.

i can't put into words how much i thank you for helping me.

thank you for helping me so much. i have a bit of trouble. i know its excessive but i didnt know how to shorten it then make it work.

my compiler error list is:

i changed what you said to this:

     cout<<"Enter Number" << numCount<< ":";
     cin>>num;
     heading();

oh i understand that thank you.

You need a variable or array to get the Quantity and Sum

does that mean i need to put
int quantity =0
int sum = 0

after int total =0?

the most i need help with is declaring Television, VideoRecorder, Camera, DVD, HiFiStereo, VideoCD. i think once i have those declared i can fix the rest.

i have an assignment due for my c++ class where we have to input from the keyboard the quantity and input from the keyboard the stock price.

so that it outputs as:
Stock Item Quantity Unit Price Total Value
----------------------------------------------
Television 5 368.00 1840.00
Video Recorder 8 268.00 2144.00
Camera 9 300.00 2700.00
DVD 10 468.00 4680.00
Hi Fi Stereo 13 2500.00 32500.00
Video CD 25 345.00 8625.00
----------------------------------------------
Gross Total: 52489.00

this is the code i have so far. i know i need to declare everything but i don't know how or where i should put it if any one has any advice that would be helpful. i hope i've given all the information you need.

Can you give a specific example of the task or better explain the problem narratively?

The word table when used in the context of C++ frequently refers to a 2 dimensional array of values and your code implements an algorhithm to accumulate value in variable called sum by adding the value of c to sum each time through the loop, so I suspect you might want to be writing code to walk through a table of values adding the value of each item in the table to generate a total value of all elements in the table. But then again I could be way of base, too.

This is how the question was given and next to it was a table with 3 columns and some amount of rows and i know your ment to go through each step that it would take to work out the final value.

Q1. Given the code below:-

int c = 0, sum = 0;
while (sum < 8)
{
c++;
sum += c;
}
cout << sum;

What is the final value of sum when the loop terminates? (1 mark)
Use the walkthrough table above.
a) 8
b) 9
c) 10
d) 11
This is the only example I could find on it and I don't really understand it.

i have this code and for an class work task and you have to do a walkthrough table and work out the output. But i dont know how you do a walkthrough table. Can someone help?

int c = 0, sum = 0;
while (sum < 8)
{
c++;
sum += c;
}
cout << sum;
