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

The C language is a general-purpose computer programming language that is widely used. The design goals of C are to provide a programming language that can be easily compiled, handle low-level memory, generate a small amount of machine code, and run without any runtime environment support. Despite providing many low-level processing capabilities, C language maintains … Read more
C programs are frequently asked questions in interviews. These programs can range from basics, arrays, strings, pointers, linked lists, file handling, etc. Let’s take a look at the list of C programs. 1) Fibonacci Sequence Without Recursion: #include <stdio.h> void printFibonacci(int n) { int a = 0, b = 1, nextTerm; for (int i = … Read more

Recently, I encountered a problem with byte endian conversion in a protocol, so I lazily went online to check it out and came across a similar issue, learning a new term called butterfly swapping. The Problem Is As Follows The protocol requires that the low byte is on the left and the high byte is … Read more
1. Embedding Assembly Language in C In microcontroller development, we usually write the main program in C language, which allows us to fully utilize the mathematical libraries and powerful data processing capabilities provided by C language tools. However, the controllability of C language is not as good as that of assembly language. For some time-sensitive … Read more
