Best IDE for Competitive Programming?

general

you can install jupyter notebook / jupyter lab, or you can use vs code with the python and competitive programming plugins installed :slight_smile:

ya , i also use this it really nice jdoodle c++

None IDE is best, Depends on our use!

47

for python-
vs code
-very easy to setup ( 2mins)
-same window run terminal

48

The better way is to use the following line in code.

#ifndef ONLINE_JUDGE
    clock();
    freopen("input.txt","r",stdin);
    freopen("output.txt","w",stdout);
#endif

Eg. Following template I use no matter which ide u are using

#include<iostream>
using namespace std;
int32_t main(){
#ifdef _MSC_VER
    _CRT_SECURE_NO_WARNINGS
#endif
#ifndef ONLINE_JUDGE
    freopen("input.txt","r",stdin);
    freopen("output.txt","w",stdout);
#endif
#pragma warning(suppress: 4101) srand(time(nullptr));
    cout << setprecision(20) << fixed;
    ios_base::sync_with_stdio(false);
    cin.tie(nullptr);
    cout.tie(nullptr);
    int t=0; cin>>t;
    while(t--) {
    }
    return 0;
}

./a.out <input.txt

Taking input from file is working but how to write in output.txt file?? I tried the following but it is showing some garbage value.

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

For easy questions : Less debugging and faster solution ==> Preferred text editor + zsh.
For medium hard questions: More Debugging ==> Clion / Intellij (Best debuggers which I have seen). Provides conditional breakpoints, custom code execution at a particular point.

P.S. Debugging is possible with terminal as well, but never got enough motivation to learn it.

I use VS code with I/O text files on the right and copy paste the test cases in input file. But it doesn’t show the runtime errors. Do I need to setup other things? I would be thankful if someone can help.

People may not believe but me and my friends still use DevCpp for C/C++ for Competitive programming with ofcourse our setups personalized to meet our uses.
It’s so light weight and incredibly fast IDE!:wink:

53

i use nvim with g+±8

54

for C and C++
I personally use Code Blocks IDE and find it very comfortable and easy to use.
I have only one cpp file and I solve all the competitive problems in that.
for JAVA
Try Eclipse IDE

Sublime Text :heart_eyes: :100:

I’ve tried so many other text editors, but sublime is the simplest and the fastest.

I call it the simplest & fastest because I didn’t like Vim (steep learning curve).

This is a case I have also faced. If the code has segmentation faults or infinite loop or recursions the code doesn’t end itself. Then what I do is goto system monitor and check which programme is consuming most cpu and then kill that process then debug the code again and repeat

Just hitting ctrl+c should stop the running program, or closing the terminal, shouldn’t it?

60

Sublime?

61

VSCODE any day.

62

Better shift to ubuntu (linux ) with #atom as editor
 Best combo!!!

To people who use sublime text does it ever happen that your antivirus fires a false negative towards your program and it shows ‘permission denied’?

I have kaspersky and it tends to block my programs sometimes when I execute them by deleting the cpp file and for a good while I cannot run the same program on the editor thus making me switch to some online IDE :upside_down_face:
