Updated on March 14, 2010

Question

Write a program to find the largest of three numbers.

If you Have set of numbers and you want to find the greatest number from among.

Code

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

void main()

{

int a,b,c;

clrscr();

printf("Enter the value of a:");

scanf("%d",&a);

printf("\nEnter the value of b:");

scanf("%d",&b);

printf("\nEnter the value of c:");

scanf("%d",&c);

if(a>b)

{if(a>c)

printf("a is largest");

else

printf("c is largest");}

else

if(b>c)

printf("b is largest");

else

printf("c is largest");

getch();

}

Output

Enter the value of a:34

Enter the value of b:334

Enter the value of c:76

B is largest

The if Keyword is followed by the test expression in parentheses. the statements of the if body should be enclosed within curly braces. The statement

if( iVar1 > iVar2 )

tests if iVar1 is greater than iVar2. if the expression is true, the message

iVar1 is Greater then iVar2

is displayed. and if the expression is false, the message

iVar2 is Greater then iVar1

is displayed.

      only if a is less than b the loop will execute else gets terminated right!

      int largest = a

      if ( b is greater than largest )

      largest = b

      if ( c is greater than largest )

      largest = c

      Wouldn't it be better to make a loop to input numbers into an array and then do a reverse sort on it?

      This would then give you the highest value of N numbers, thus reducing your number of lines of code.
