Thread: min and maximum number

hey how do you find the minimum and maximum of entered numbers

suppose some one enters 5,4,9,2,3,1,7,8

and then find out the maximum and minimum from them

i have the program coded but I'm getting errors in the maximum number

Code:

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    const int SZ = 7;
    double sales[SZ];
    int x;
    double lowest = sales[0];
    double highest = sales[0];
   for(x = 0; x < SZ; x++)
    {
        cout<<"Enter sales for day "<<(x + 1)<<" >> ";
        cin>>sales[x];

    }
    cout<<"The entered sales are: ";
    for(x = 0; x< SZ; x++) {
     cout<<sales[x]<<"  ";
    }

     for ( int x = 0; x < SZ; x++ ) {
         if ( highest < sales[x] ) {
           highest = sales[x];
         }


     }
     for ( int x = 0; x < SZ; x++ ) {


        if( sales[x] < lowest ) {
        lowest = sales[x];
        }

     }
     cout<<"\nThe lowest sale is "<<lowest<<endl;
     cout<<"\nThe highest sale is "<<highest<<endl;


      getch();
     }

the minimum number is fine but a wierd number appears in the highest number

you meant this ??

Code:

#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    const int SZ = 7;
    double sales[SZ];
    int x;
    double lowest = sales[0];
    double highest = sales[0];
   for(x = 0; x < SZ; x++)
    {
        cout<<"Enter sales for day "<<(x + 1)<<" >> ";
        cin>>sales[x];

    }
    cout<<"The entered sales are: ";
    for(x = 0; x< SZ; x++) {
     cout<<sales[x]<<"  ";
    }

     for ( int x = 0; x < SZ; x++ ) {
         if ( sales[x+1] > highest ) {
           highest = sales[x];
         }


     }
     for ( int x = 0; x < SZ; x++ ) {


        if( sales[x+1] < lowest ) {
        lowest = sales[x];
        }

     }
     cout<<"\nThe lowest sale is "<<lowest<<endl;
     cout<<"\nThe highest sale is "<<highest<<endl;


      getch();
     }

however the largest number isn't still working

Here:

Code:

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

using namespace std;

int main()
{
    const int SZ = 7;
    double sales[SZ];
	
	//Don't define x here

    double highest = 0; //Initialize with 0, we will be assigning it a value later

    for(int x = 0; x < SZ; x++) //Define x in each of the for statements
    {
        cout << "Enter sales for day " << (x + 1) << " >> ";
        cin >> sales[x];
    }

    cout<<"The entered sales are: ";

    for(int x = 0; x< SZ; x++) 
	{
		cout<< sales[x] << "  ";
    }

    for ( int x = 0; x < SZ; x++ ) 
	{
		if ( sales[x] > highest ) //Don't put sales[x] + 1, you want to scroll through ALL the values
		{
			highest = sales[x];
        }
    }
	
	double lowest = highest; //Lowest goes here because we need the highest value to initially go in it

	for ( int x = 0; x < SZ; x++ ) 
	{
		 if( sales[x] < lowest ) //Again, no + 1
		 {
			lowest = sales[x];
         }
	}

	cout<<"\nThe lowest sale is "<<lowest<<endl;
	cout<<"\nThe highest sale is "<<highest<<endl;

	getch();
}

I fixed it up, I commented the errors so you should understand. I tested it. And it was only a couple of careless things you did wrong. Hopefully you learn from it.
