Biggest of 3 Numbers Using Ternary Operator in C

Here is a program to find biggest of 3 numbers using ternary operator with output and explanation in C programming language.

# include <stdio.h> 
# include <conio.h> 
void main() 
{ 
 int a, b, c, big ; 
 clrscr() ; 
 printf("Enter three numbers : ") ; 
 scanf("%d %d %d", &a, &b, &c) ; 
 big = (a > b) ? ((a > c) ? a : c) : ((b > c) ? b : c) ; 
 printf("\nThe biggest number is : %d", big) ; 
 getch() ; 
}

Output of above program

Enter three numbers : 20    30      10

The biggest number is : 30 

Explanation of above program

Note: If you don't know about ternary operator first read it here. Ternary Operator in C.

To understand this program lets convert this ternary operator into its equivalent if else.

 

big = (a > b) ? ((a > c) ? a : c) : ((b > c) ? b : c) ; 

 If else equivalent of above ternary expression 
 

if(a > b){
  if(a > c){
    big = a;
  }else{
    big = c;
  }
}
else{
  if(b > c){
    big = b;
  }else{
    big = c;
  }
}

Now once ternary operator's expression is converted into simple if else it is easy to understand the program. So I let you to it.
