C – Find Largest Number – Dynamic Memory Allocation Code Example

The code for Find Largest Number – Dynamic Memory Allocation

#include<stdio.h>
#include<stdlib.h>

int main()
{
   int i, number;
   float *var;

   printf("Enter total number of elements(1 to 100): ");
   scanf("%d",&number);

   // allocates the memory for 'number' elements
   var=(float*)calloc(number,sizeof(float));

   if(var==NULL)
   {
      printf("Error! Memory not Allocated.");
      exit(0);
   }

   printf("\n");

   // store the number entered by the User
   for(i=0;i<number;i++)
   {
      printf("Enter element [%d]: ",i+1);
      scanf("%f",var+i);
   }

   // store largest number at address var
   for(i=0;i<number;i++)
   {
      if( *var < *(var+i))
         *var = *(var+i);
   }

   printf("Largest Element = %.2f",*var);

   return 0;
}

/*
Output
Enter total number of elements(1 to 100): 3

Enter element [1]: 1.23
Enter element [2]: 4.67
Enter element [3]: 1.09
Largest Element = 4.67
