C program to find largest number using dynamic memory allocation

PROGRAM:

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

int main()
{
    int i, num;
    float *data;

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

   
    data = (float*) calloc(num, sizeof(float));

    if(data == NULL)
    {
        printf("Error!!! memory not allocated.");
        exit(0);
    }

    printf("\n");

   
    for(i = 0; i < num; ++i)
    {
       printf("Enter Number %d: ", i + 1);
       scanf("%f", data + i);
    }

    for(i = 1; i < num; ++i)
    {
       
       if(*data < *(data + i))
           *data = *(data + i);
    }

    printf("Largest element = %.2f", *data);

    return 0;
}

OUTPUT:

Enter total number of elements(1 to 100): 10

Enter Number 1: 2.34
Enter Number 2: 3.43
Enter Number 3: 6.78
Enter Number 4: 2.45
Enter Number 5: 7.64
Enter Number 6: 9.05
Enter Number 7: -3.45
Enter Number 8: -9.99
Enter Number 9: 5.67
Enter Number 10: 34.95
Largest element: 34.95
