program to find smallest and largest integer among 5 integer values

glacier · #1 13-Sep-2006, 17:52

Hey friends,

I need to know if i am making any mistake while doing this.
I have to make a program finding out smallest and largest number among five user input integers. The biggest problem is I only have to use "if" statement.

Please help me at the earliest !!

CPP / C++ / C Code:

int main()
{

int a;
int b;
int c;
int d;
int e;
int largest, smallest;

cout << "Please enter first number: ";
 cin >> a ;

cout << "Please enter Second number: ";
 cin >> b ;

cout << "Please enter third number: ";
 cin >> c ;

cout << "Please enter fourth number: ";
 cin >> d ;

cout << "Please enter fifth number: ";
 cin >> e ;

if (a<b)
cout << smallest << ":" <<largest<<endl ;
if (a<c)
cout << smallest << ":" <<largest <<endl ;
if (a<d)  
cout << smallest << ":" <<largest<<endl ;
if (a<e)
cout << smallest << ":" <<largest<<endl ;

if (b<a)
cout << smallest << ":" <<largest <<endl ;
if (b<c)
cout << smallest << ":" <<largest<<endl ;
if (b<d)
cout << smallest << ":" <<largest<<endl ;
if (b<e)
cout << smallest << ":" <<largest<<endl ;

if (c<a)
cout << smallest << ":" <<largest<<endl ;
if (c<b)
cout << smallest << ":" <<largest<<endl ;
if (c<d)
cout << smallest << ":" <<largest<<endl ;
if (c<e)
cout << smallest << ":" <<largest<<endl ;
if (d<a)
cout << smallest << ":" <<largest<<endl ;
if (d<b)
cout << smallest << ":" <<largest<<endl ;
if (d<c)
cout << smallest << ":" <<largest<<endl ;
if (c<e)
cout << smallest << ":" <<largest<<endl ;

if (e<a)
cout << smallest << ":" <<largest<<endl ;
if (e<b)
cout << smallest << ":" <<largest<<endl ;
if (e<c)
cout << smallest << ":" <<largest<<endl ;
if (e<d)
cout << smallest << ":" <<largest<<endl ;

return 0;

}

Yes. A lot. First and foremost is you skipped reading the "Please Read This" post.

That's not a problem. You only need a 8 of them.

CPP / C++ / C Code:

int main()
{
    int a;
    int b;
    int c;
    int d;
    int e;
    int largest, smallest;

    cout << "Please enter first number: ";
    cin >> a ;

    cout << "Please enter Second number: ";
    cin >> b ;

    cout << "Please enter third number: ";
    cin >> c ;

    cout << "Please enter fourth number: ";
    cin >> d ;

    cout << "Please enter fifth number: ";
    cin >> e ;

    // What's the value of the variable "smallest" and "largest"?
    // Nothing was ever initialized.
    if (a<b)
    cout << smallest << ":" <<largest<<endl ;
    if (a<c)
    cout << smallest << ":" <<largest <<endl ;
    if (a<d)  
...
}

If you need the smallest value, start by loading a into smallest. Then test the rest of the variables against smallest and if any are smaller, replace.

Then do the same with largest.

At the end, output the result.
