Some important points about Global variable declaration are:
&
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.
Below is a program to find largest and smallest value using global declaration.
#include<stdio.h>
int a,b;
int main()
{
printf("\n\n\t\tStudytonight - Best place to learn\n\n\n");
printf("\n\nEnter the two values to find the greatest and smallest number: \n");
scanf("%d%d", &a, &b);
if(a == b)
printf("Both are equal\n");
else if(a < b)
{
printf("\n\nThe largest number is %03d\n", b);
printf("\nThe smallest number is %03d\n", a);
printf("\nThe largest number is %03d\n", b);
}
else //Only possibility remaining
{
printf("The largest number is %03d\n", a);
printf("The smallest number is %03d\n", b);
}
printf("\n\n\t\t\tCoding is Fun !\n\n\n");
return 0;
}
