Print The Largest And Smallest Using Global Declaration

Some important points to be note about Global variable declaration are:

It can be used anywhere within the program. Unlike local variables that can be used within the scope of a particular function.
& is used to assign the input value to the variable and store it at that particular location.
%0nd is used to represent numbers in n digit format with leading 0’s.

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

int a,b;
void main()
{
    clrscr();

    printf("Enter the two values to find the greatest and smallest number: \n");
    scanf("%d%d", &a, &b);

    if(a == b)
        printf("\n\nBoth are equal");   
    else if(a < b)
    {
        printf("\n\nThe largest number is %03d\n", b);
        printf("\nThe smallest number is %03d\n", a);
    }
    else    //Only possibility remaining
    {
        printf("The largest number is %03d\n", a);
        printf("The smallest number is %03d\n", b);
    }
    getch();
}

OutPut

Enter the two values to find the greatest and smallest number:
10
7


The largest number is 010
The smallest number is 007
