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

What is Pointer? A pointer in C is a variable that stores the address of another variable. This variable can be an int, char, array, function or any other parameter. The size of Syntax int n = 10; int * p = &n; // Variable p of type pointer is pointing to the address of the variable n of type integer. the array depends on the architecture. However, on 32-bit architectures, the size of the pointer is 2

Passing Array to Function in C There are many problems in C where it is necessary to pass multiple variables of the same type to a function. For example, consider a function that sorts 10 items in ascending order. This type of work should exceed 10 digits by default from the main function. Here, instead

Multi dimensional Array In the previous section, you learned about arrays, also known as one-dimensional arrays. These are great and I will be using them a lot when programming in C. However, if you want to store data in a tabular format (like a table with rows and columns), you need to know more about
