C Program To Find Largest And Smallest of Three Numbers Using if else

Algorithm -:

Program Start
Variable Declaration
Input three number
Check the condition
Display Largest Number
Display Smallest Number
Program End

Program -:

//C program to find Largest and smallest among three numbers Using if else

#include<stdio.h>
void main()
{
  // Variable declaration
   int a,b,c, larg, small;

   printf("Enter Three Number\n");
   scanf("%d %d %d",&a,&b,&c);

  // larg among a, b and c
  if(a>b)
  {
      if(a>c)
        larg = a;
      else
        larg = c;
  }
  else
  {
      if(b>c)
        larg = b;
      else
        larg = c;
  }
 // Small among a, b and c
  if(a<b)
  {
      if(a<c)
        small = a;
      else
        small = c;
  }
  else
  {
      if(b<c)
        small = b;
      else
        small = c;
  }
//Display Largest Number
 printf("%d is largest number\n",larg);

//Display smallest number
 printf("%d is Smallest Number ",small);

return 0;
}

Output -:

Enter Three Numbers
119
372
721

721 is largest number
119 is Smallest Number

C Program To Find Largest And Smallest of Three Numbers Using function

Program -:

//C program to find the Largest and smallest of three numbers Using Function

#include<stdio.h>
void larg(int, int, int);
void small(int, int, int);
int main()
{
  // Variable declaration
   int a,b,c;

   printf("Enter Three Numbers\n");
   scanf("%d %d %d",&a,&b,&c);

   //calling function to find Largest number
    larg(a,b,c);
    small(a,b,c);

   return 0;
}
void larg(int a, int b, int c)
{  int larg;
     // Larg among a, b and c
  if(a>b)
  {
      if(a>c)
        larg = a;
      else
        larg = c;
  }
  else
  {
      if(b>c)
        larg = b;
      else
        larg = c;
  }
//Display Largest number
    printf("Largest Number is : %d",larg);
}
void small(int a, int b, int c)
{  int small;
     // Small among a, b and c
  if(a<b)
  {
      if(a<c)
        small = a;
      else
        small = c;
  }
  else
  {
      if(b<c)
        small = b;
      else
        small = c;
  }

  //Display smallest number
    printf("\nSmallest Number is : %d",small);

}

Output -:

Enter Three Numbers
20
34
22

Largest number is 34
Smallest Number is 20

C Program To Find Largest And Smallest of Three Numbers Using Conditional Operator

Program -:

//C program to find largest and smallest among three numbers using ternary operator

#include<stdio.h>

void main()
{
  // Variable declaration
   int a,b,c,larg,small;

   printf("Enter three number\n");
   scanf("%d %d %d",&a,&b, &c);

 // Largest among a, b and c
   larg = a>b?a>c?a:c:b>c?b:c;

   // Small among a, b and c
   small = a<b?a<c?a:c:b<c?b:c;

 //Display largest number
   printf("Largest Number is : %d\n",larg);

//Display smallest number
   printf("Smallest Among 3 Number is : %d",small);

}

Output -:

Enter Three Numbers
2
4
1

Largest number is 4
Smallest Number is 1
