🚀 Getting Started

Prerequisites

• GCC compiler or any C compiler
• Windows environment (some programs use Windows-specific libraries)
• Basic understanding of C programming

Installation

1. Clone the repository:

   git clone https://github.com/AlexBesios/First-Semester-C-Programs.git

2. Navigate to the project directory:

   cd First-Semester-C-Programs

🔨 Compilation Instructions

Each program can be compiled using GCC. Navigate to the specific program directory and use:

gcc code.c -o program_name.exe

For programs with specific names:

gcc hangman.c -o hangman.exe
gcc ASCII.c -o ASCII.exe
gcc Dice.c -o Dice.exe

Running Programs

After compilation, run the executable:

./program_name.exe
