In C, it is possible to allocate memory dynamically. Dynamic memory allocation is useful when the required memory size changes at runtime or when large memory areas are needed. This article explains how to allocate memory dynamically and provides some points of caution. # Functions for Dynamic Memory Allocation and Deallocation The C standard library provides functions for dynamic memory allocation and deallocation. #include <stdlib.h> void *malloc(size_t size); void free(void *ptr); void *calloc(size_t nmemb, size_t size); void *realloc(void *ptr, size_t size); To use these functions, include stdlib.

During development, you may encounter situations where you need to allocate multiple dynamic memory blocks within a function. If memory allocation fails, you’ll need to free any previously allocated memory, which can make error handling complex. This article explains how to simplify error handling and manage memory deallocation by using the goto statement. # What is the goto Statement? The goto statement is a syntax used to jump to a specified label within a function.
