Write a program to implement generic pointer.

#include <stdio.h>
#define SIZE 10
void printArray(void * vPtr, int size, int type);
int main()
{
    int num[SIZE] = {10, 20, 30, 40, 50, 60,70, 80, 90, 100};
    float fractional[SIZE] = {1.1f, 1.2f, 1.3f,1.4f, 1.5f, 1.6f, 1.7f, 1.8f, 1.9f, 2.0f};
    char characters[SIZE] = {'C', 'o', 'd', 'e','f', 'o', 'r', 'w', 'i', 'n'};

    printf("\nElements of integer array: ");
    printArray(&num, SIZE, 1);

    printf("\nElements of float array: ");
    printArray(&fractional, SIZE, 2);

    printf("\nElements of character array: ");
    printArray(&characters, SIZE, 3);
    return 0;
}
void printArray(void * vPtr, int size, int type)
{
    int i; 
    for(i=0; i<size; i++)
    {
        switch(type)
        {
            case 1: 
                printf("%d, ", *((int *)vPtr + i));
            break;
            case 2: 
                printf("%.2f, ", *((float *)vPtr + i));
            break;
            case 3: 
                printf("%c, ", *((char *)vPtr + i));
            break;
        }
    }
}

Output

Elements of integer array: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 
Elements of float array: 1.10, 1.20, 1.30, 1.40, 1.50, 1.60, 1.70, 1.80, 1.90, 2.00, 
Elements of character array: C, o, d, e, f, o, r, w, i, n,
