The most common errors related to pointers and memory management are dangling pointers. Sometimes, programmers fail to initialize pointers with a valid address, and such uninitialized pointers are called dangling pointers in C language. Dangling pointers occur when an object is destroyed, and the pointer’s value is not modified when the object is deleted or … Read more
Pointers in C language are variables that store the address of another variable. This variable can be an int, char, array, function, or any other pointer type. The size of a pointer depends on the computer architecture. However, in a 32-bit computer architecture, the size of a pointer is 2 bytes. Consider the following example … Read more
