If no memory is allocated, error is displayed and the program is terminated. #include <stdio.h> #include <stdlib.h> int main() { int i, j; float *data; printf("Enter total number of elements(1 to 100): "); scanf("%d", &j); // Allocates the memory for 'j' elements. data = (float*) calloc(j, 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 < j; ++i) { printf("Enter Number %d: ", i + 1); scanf("%f", data + i); } // Loop to store largest number at address data for(i = 1; i < j; ++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; }
