Quick Start with Online Tools

Using Compiler Explorer:

1. Go to https://godbolt.org/
2. Select "x86-64 gcc" as compiler
3. Write a simple C program:

#include <stdio.h>
int main() {
    printf("Hello, World!\n");
    return 0;
}

1. View the assembly output in the right panel
2. Experiment with different optimizations

Using OnlineGDB:

1. Go to https://www.onlinegdb.com/
2. Select "C" as language
3. Write your C program
4. Compile and run
5. Use the "Debug" feature to see assembly

Recommended Learning Path

1. Start with C to Assembly: Write simple C programs and examine the assembly output
2. Learn Basic Instructions: MOV, ADD, SUB, JMP, etc.
3. Understand Registers: AX, BX, CX, DX, etc.
4. Practice with Online Simulators: Use the tools above
5. Progress to Complex Programs: Loops, functions, system calls

Installation Guide (Optional)

If you want to install assembly tools locally:

Option 1: Install NASM and GCC

1. Download NASM from: https://www.nasm.us/
2. Install MinGW-w64 for GCC: https://www.mingw-w64.org/
3. Add to PATH environment variable

Option 2: Install Visual Studio

1. Download Visual Studio Community (free)
2. Install with C++ development tools
3. Use MASM (Microsoft Macro Assembler)

Option 3: Use WSL (Windows Subsystem for Linux)

1. Install WSL from Microsoft Store
2. Install Ubuntu or other Linux distribution
3. Install NASM and GCC in Linux environment
