First, let’s pose a question: what do you think the output of the following code will be? /* A simple example code */ #include <stdio.h> int main(int argc, char const *argv[]) { int a = -10; int b = 10; int c = -3; int d = 3; printf("Result 1: %d\n", a%d); printf("Result 2: %d\n", … Read more
In the world of C programming, code safety and resource management have always been crucial topics. Today, we will focus on a feature that is expected to become an important part of future versions of C language: ‘defer’. We will explore how to apply this feature in existing tools and compilers, as well as its … Read more
Today, let’s talk about the C language. When I first started learning, I was also confused, thinking it seemed simple, but I encountered various problems when using it. After years of trial and error, I would like to share some of my insights with you. Here are examples of using selection statements in C language: … Read more
