Program To Find Largest of Three Numbers Using Function

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

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

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

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

 //Display Largest number
    printf("Largest Number is : %d",l);

   return 0;
}
int 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;
  }

}

Output -:

Enter Three Numbers
10
19
13

Largest Number is : 19
