test_dynamic_buffers.c

// The following code examines multiple routines of definining dynamic buffers in C.
// This file fires a runtime malloc() error due to a HEAP corruption error; because of buffer overflow.
// Two maneuvers are introduced to fix this 

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

int main() {
    
    // buffers
    const char *value1 = "Hi";
    const char *value2 = "Hello\n Dynamic Buffers!";
    
    // pointer to buffers
    const char **inputs = malloc(sizeof(char *));
    
    // automatic allocation of address buffer ???
    // appends new addresses to the buffer automatically!
    *inputs = value1;
    *(inputs + 1) = value2;
    *(inputs + 2) = value1;
    *(inputs + 3) = value1;
    *(inputs + 4) = value1;
    
    // printf("%s\n", ((const char*) inputs[2]));
    // printf("%s\n", ((const char*) inputs[2]));
    
    free((void *) inputs);
    
    return 0;
