From today, I will be starting lessons on C programming in my ALX Software Engineering class and I look forward to sharing with you everything I learn through this series.
In the previous lessons, you learned: What the preprocessor is How #include and #define work How macros and conditional compilation behave Now we bring everything together. How is the preprocess
In the previous lesson, you learned: What the preprocessor is How #include works How #define replaces text Now we go deeper. This lesson is where things become powerful (and a bit tricky): Macro
So far, you’ve been writing C programs like this: #include <stdio.h> int main(void) { printf("Hello, world!\n"); return 0; } You write the code → compile → run. Simple. But here’s something
So far, you’ve learned: How programs receive input (argc, argv) How to access and process arguments Now we complete the picture. This lesson answers three important questions: Why does main some
In the previous lesson, you learned: What command-line arguments are What argc and argv mean How programs receive input from the terminal Now we move to the practical side: How do we actually us
Up to this point, most of your C programs have looked like this: int x = 5; You hardcode values directly inside the program. That works… but it’s limited. What if you want your program to behave diff
