Bash 中的 Execute.cpp 文件 | Ubuntu 18.04

Question

Following these instructions , I want to compile this .cpp code.

So far, I have 'vectori s e.cpp' and file named ' a .out'.

However, I'm not sure that I need 'a.out'.

Following these instructions , I want to execute 'vectori s e.cpp' like so (notice ' s ' and not ' z '):

g++ vectorise.cpp -o vectorise -fopenmp --std=c++17

This is for vectorising .fastq files, which I already have.

This is my terminal currently. What steps can I now follow to exe 'vectori s e.cpp'?

Attempting to copy files into this directory gives Permission Denied:

I wanna give a massive shout out to the squad-fam in the above comment for giving their help in-hand. This is the code that brought your boy home, to where he belongs:

sudo chmod 777 .
sudo rm a.out
g++ vectorise.cpp -o vectorise -fopenmp --std=c++17

First set your directory to the file which you wish to execute this can be done using cd the type sudo gedit nameoffile.cpp after ./a.out .
