Checks the runtime of your program with given input file, also generating the output file. Use this to avoid TLE penalties on online judges, check your runtime beforehand !!

runtimeChecker

Calculate the total runtime of your program.

Steps to run

1. Download runtimeChecker.cpp

Simply download the individual file and put in same folder as your program. (recommended, however different directories will also work perfectly fine)

2. Compile and link using g++.

Open Terminal. Go to folder containing runtimeChecker.cpp. Then use the following command in terminal. (note gcc/g++ is a prerequisite) (This code works on various Linux distros including Ubuntu, please refer the internet for similar commands in Windows.)

g++ runtimeChecker.cpp -o a.out

3. Compile your program, make its executable.

If your program is in c++, use g++ command

g++ <your_program_name> -o <exec_name>

As an example, I have included the file example_program.cpp which finds fibonacci(n). We compile it as follows

g++ example_program.cpp -o p.out

4. Make the input file

Make the input file with input in it, and save in same directory. Name it input.txt As an example I have made input.txt also for example_program.cpp, you can change its contents after downloading on your machine if you want.

5. Check runtime!

Run the following command in terminal.

./a.out ./<exec_name> input.txt output.txt

As an example,

./a.out ./p.out input.txt output.txt

This gives the output -

At the end, runtimeChecker helps you in following ways

• Runs your program using input.txt as stdin
• Puts the output from stdout into a new file output.txt
• Displays the error from stderr stream in terminal.
• Calculates and displays running time of your program.

Note, write correct file paths (eg, use ../ to go up) if the directory for any file is different

Thanks for using !
