Debugging and Execution Time Measurement Toolkit

This repository contains two scripts, Dprintf.sh and measure.sh, designed to aid in debugging and measuring the execution time of C code respectively.

Dprintf.sh

Dprintf.sh is a bash script intended for debugging C code by automatically adding printf() statements before every curly bracket { to help identify where the code gets stuck during execution.

Usage

1. Place Dprintf.sh in the directory containing your C source file.
2. Open a terminal and navigate to the directory containing both Dprintf.sh and your C source file.
3. Run the script using the command:

   ./Dprintf.sh your_source_file.c
   

4. This will generate a new file named debug_your_source_file.c with printf() statements inserted before each { in your code.

measure.sh

measure.sh is a bash script used to measure the execution time of C code. It runs the code multiple times and calculates the average execution time.

Usage

1. Place measure.sh in the directory containing your C source file.
2. Open a terminal and navigate to the directory containing both measure.sh and your C source file.
3. Run the script using the command:

   ./measure.sh your_source_file.c
   

4. This will compile your_source_file.c and execute it multiple times, measuring the execution time each time.
5. Finally, it will display the average execution time of your code.

Note

• These scripts are intended to be used with C source files.
• Make sure you have appropriate permissions to execute the scripts (chmod +x Dprintf.sh measure.sh).
• Always review the modified/debugged code before running it in a production environment.
• For accurate measurement results, it's recommended to compile the C code with optimizations disabled (-O0 for GCC).
• These scripts can help in debugging and performance tuning, but they should not be solely relied upon for critical applications. Always use proper debugging and profiling tools for comprehensive analysis.
