0x09.C - Static Libraries 📚

This directory contains tasks related to creating and using static libraries in the context of the C programming language. It demonstrates the implementation of utility functions, creating static libraries, and utilizing them in a test program.

Task 0: Creating Static Library 🛠️

In this task, a static library named libmy.a is created. It includes utility functions with the following prototypes:

• int _putchar(char c);
• int _islower(int c);
• int _isalpha(int c);
• int _abs(int n);
• int _isupper(int c);
• int _isdigit(int c);
• int _strlen(char *s);
• void _puts(char *s);
• char *_strcpy(char *dest, char *src);
• int _atoi(char *s);
• char *_strcat(char *dest, char *src);
• char *_strncat(char *dest, char *src, int n);
• char *_strncpy(char *dest, char *src, int n);
• int _strcmp(char *s1, char *s2);
• char *_memset(char *s, char b, unsigned int n);
• char *_memcpy(char *dest, char *src, unsigned int n);
• char *_strchr(char *s, char c);
• unsigned int _strspn(char *s, char *accept);
• char *_strpbrk(char *s, char *accept);
• char *_strstr(char *haystack, char *needle);

📦 Created libmy.a and stored utility functions.

Task 1: Using Static Library and Test Program 💻

This task demonstrates the usage of the created static library in a test program. Key steps:

1. Compiled utility functions into object files.
2. Created liball.a static library with a script.
3. Compiled test program main.c using the static library.
4. Ran the test program for validation.

🛠️ Compiled utility functions, created liball.a, and verified through test program.
