ubuntu build debugging environment based VSCode the C ++ programming language to build guide
First install g ++
sudo apt install g++
- Check whether the installation was successful:
Plug in the plug-in bar c / c ++, code runner:
First, write a simple demo.cpp file:
'''
#include<iostream>
using namespace std;
int main()
{
int i = 0 ;
int num =0;
for ( ; i < 10; i++)
{
num += i;
}
cout<<"结果是"<<num<<endl;
return 0;
}
'''
Generate a configuration file tasks.json:
- Terminal -> Default configuration generation task
- input ctrl + shift + p c / c ++ appears in the command line
