Example: Find Largest Element Using Dynamic Memory Allocation - calloc()

Dynamic Memory Allocation - calloc()
#include
#include

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

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

// Allocates the memory for 'num' elements.
data = (float*) calloc(num, sizeof(float));

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

printf("\n");

// Stores the number entered by the user.
for(i = 0; i < num; ++i)
{
printf("Enter Number %d: ", i + 1);
scanf("%f", data + i);
}

// Loop to store largest number at address data
for(i = 1; i < num; ++i)
{
// Change < to > if you want to find the smallest number
if(*data < *(data + i))
*data = *(data + i);
}

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

return 0;
