In Golang, pointers are variables that store the memory address of another variable. They are often used to reference large data structures and avoid copying the entire data structure. In addition to the memory address, a pointer also has a capacity. The capacity of a pointer is the maximum number of elements that can be stored in the memory block it references. Finding the capacity of a pointer is an important task for any Golang developer. In this article, we will explore how to find the capacity of a pointer in Golang. Understanding Pointers in Golang Before diving into the ... Read More
