I'm trying to write a program in C++ that will tell the user to input 5 numbers and it'll display the largest number and whether it was the 1st, 2nd 3rd...so on entry. any help? this is what I have so far

#include "stdafx.h"
#include <iostream>
#include <math.h>
#include <iomanip>
using namespace std;

const int MAXNUMS = 5;
    int count;
    double num;
int _tmain()

{

    cout << "This program will find the largest number of " << MAXNUMS << " numbers you enter.\n";
    cout << endl;
    count = 1;
    while (count <= MAXNUMS)
    {
        cout << "\n Enter a number: ";
        cin >> num;
        cout << "The number you entered is " << num;

            count++;

    cout << endl;
    return 0;

Please wrap your code in "code" tags. Also, please give us a sample input, the current output, and the expected output.

I don't think you need this: #include "stdafx.h" You should use #include <cmath> instead of #include <math.h> Another rule is that you should pretty much never use using namespace std; Dave

Your going to have to make an array of 5 to store the inputs in so...

int nums[MAXNUMS];
count = 0;
// get input
while(count < MAXNUMS)
{
    cout << "Num: ";
    cin >> nums[count];
    cin.ignore();
}
// sort here

You should be using some sort of linear data-structure ( an array or a vector). Consider an array:

Arr         _______________________
    Pos:    | 0 | 1 | 2  | 3  | 4 |
            |___+___+____+____+___|
    Value:  | 1 | 5 | 10 | 23 | 8 |
            |___|___|____|____|___|

We find the largest number by the following algorithm:
Algorithm to find the maximum MAX of an array of length N.
1. Initialize: Set k=0 and MAX to Arr[k]
2. Check: Check if Arr[k]>Arr[k+1]
2.1 Yes: Set k=k+1
2.2 No: MAX=Arr[k+1]. Set k=k+1
3 Check overflow: Check if k==N-1
3.1 Yes: STOP
3.4 No: Go to Step 2

Hence you get the MAX as the largest value.

Always post your code in the post tags:
[code=cplusplus] //your code goes here

[/code]
PS; Did anyone noticed that I am quite good at making pictorials using simple ASCII characters?

well dont do this kind of hard working in a simple programm

  1. Take array of 5 elements a[5] as u can scan the 5 numbers.
  2. Also take another variable "temp" (for temporary use).
  3. Now swapping & comparing every element of a[5] get the largest number.

see in my programm...

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

void main()
{
    int a[5],temp,i,j;
    clrscr();
    for(i=0;i<5;i++)
    {
        cout<<"Enter "<<i<<" element:-- ";
        cin>>a[i];
    }
    for(i=0;i<5;i++)
    {
        for(j=0;j<5;j++)
        {
            if(a[j]>a[j+1])
            {
                temp=a[j];
                a[j]=a[j+1];
                a[j+1]=temp;
            }
        }
    }


    cout<<endl<<"Maximam Number:--"<<a[j];
    getch();
}

copy\paste my prog in tour TC..

now suppose you have to find minimun number then
you just have to change the condication instead of " if(a[j]>a[j+1]) " u have to write " if (a[j]<a[j+1]) "....try it also
okay..

I am not agree with you.

zeus1216gw,

First, Your source code should be surrounded with bb code tags. Second, follow-up siddhant3s's post.

daviddoria>I don't think you need this: #include "stdafx.h"
-- OP uses Visual Studio - Visual C++.
daviddoria>Another rule is that you should pretty much never use using namespace std;
-- Don't put your own words.

nirav99>well dont do this kind of hard working in a simple programm. copy\paste my prog in tour TC..

-- !!TC!!
OP's program has a problems but I think you have more
problems then OP's program.
