## [C++](https://github.com/rishabhdeepsingh/Competitive/tree/master/Cpp)

# Bash testing for C++

In ubuntu we can use the following code to check the time

    

    time ./a.out < in 

    time ./generator | ./a

    

## Using generator

    

    #!/bin/bash

    g++ -o gen gen.cpp

    g++ -o main main.cpp

    g++ -o brute brute.cpp

    for((i = 1;;++i));do

        echo $i

        ./gen $i > inputt

        diff -w <(./main < inputt) <(./brute < inputt) || break

    done

To copy a single file to multiple Files

    echo a.cpp b.cpp d.cpp | xargs -n 1 cp template.cpp

    

## Compile

### Normal

    g++ -O2 -std=c++17 -Wno-unused-result -Wshadow -Wall -o "%e" "%f"

### Debugging

    g++ -DLOCAL -std=c++17 -Wshadow -Wall -o "%e" "%f" -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG -g
