sizeof() operator The size operator is the most frequently used operator in C. It is a compile-time unary operator that calculates the size of its operand. Returns the size of the variable. It can be used for any data type, floating point type, floating point type, and measurement type conversion. When sizeof() is used with […]

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

What is Pointers and Addresses? Let us begin with a simplified picture of how memory is organized. A typical machine has an array of consecutively numbered or addressed memory cells that may be manipulated individually or in contiguous groups. One common situation is that any byte can be a char, a pair of one-byte cells
