Dangling Pointers? The most common error with pointers and memory management is dangling/crazy pointers. Sometimes programmers fail to initialize a pointer with a valid address, so this type of initialization is called dangling pointer in C. A dangling pointer occurs when objects are removed from memory without updating the value of the pointer, or when

Pointer Arithmetic? We can perform arithmetic operations such as addition and subtraction of indicators. However, we know that the pointer has an address and if the other operand is an integer type, the result of the arithmetic operation to be performed on the pointer will also be a pointer. Subtracting meters from meters will result

Pointers and Function Arguments? Pointers are used as function parameters to hold the address of the parameter when calling the function. This is also called searching. When a function is called by a reference, any changes made to the reference also affect the original variable. Example Swapping two numbers using Pointer #include <stdio.h> // Function
