I'm trying to change a char to an int using the stdlib.h atoi function
It works perfectly on windows using VC++ however on Ubuntu
Linux using g++ the value of t is off and from is correct.

Stoi Not Working Dev C 2017
When I try to compile a simple number game with cygwin 4.9.3-1, it says stoi was not declared in this scope. I don't know what I'm doing wrong, and cannot find a way to fix it. Jul 19, 2017 I’ve been working on a chess game in C to improve my problem solving skills, etc. I started with an in-browser IDE at work, and finally moved it to C::B today. However, C::B keeps saying that std::stoi is not declared. I switched on -std=c11 in the compiler settings, and it still isn’t working. I noticed to my glee that C11 has a std::sto@ family of functions for easily unpacking ints/floats/longs whatever from strings. I'm surprised however, that the opposite isn't implemented.
For example when i input
from = 2 which is 50
to = 6 which is 54
from = 2 which is 50
to = 6 which is 54
f=2
t=62
t=62
This appears to be adding from and to together 50 + 54
and the using atoi on that then uses atoi on to on its own and
adds them together
and the using atoi on that then uses atoi on to on its own and
adds them together
50 + 54 = 104
104 -48 = 56 + 6 = 62
104 -48 = 56 + 6 = 62
On a few different tests it seems to follow this pattern
My question is why is this happening using g++ and not VC++

Simply creating values of the right type isn't enough. You need to know what's going to happen next.

atoi() expects an ARRAY of characters ending in a 0 character.
This, you do not have. You have a single char and undefined values following it (so yes, you get garbage).

It works just the same.
The only difference is, you got lucky with the junk being 0.

If you are getting the error that g++.exe has stopped working , you might be using Bloodshed Dev C++ in Windows 8 /8.1/10 Operating System. Whatever it may be I’ve faced this problem several times during executing my programs in the Dev C++ compiler . It generally happens when you install Dev C++ and try to compile a cpp file in Windows 8/8.1 or in Windows 10, a windows pops-up saying that g++ has stopped working. Its not so easy to figure out the problem as not all of you might be using same version of Dev C++ Compiler and may be even on different Operating Systems.Whatever it may be , in this post I will discuss a few methods. Any of these method might work for you. I recommend to follow each method step by step and follow each method one after another.
- How to fix g++.exe has stopped working problem?
Method 1
In this method , it is just changing of various parameters , this could fix the g++ has stopped working error. I recommend this method for 64-bit users ( people mostly using laptops are 64 bit ) and I recommend Method 2 for x86 ( 32-bit users ).
Click on Tools in the top bar as shown in the screenshot and select Compiler Options
Step 2 :
Select Programs pane in the Compiler Options window and change the gcc , c++ , make parameters.
Note:
- In the newer versions make still stands as mingw32-make.exe , don’t change it.
- These parameters may be same be shown in your Dev C++ Compiler ( based on the version ) , if problem still persists , skip to the next Method.
If the above method , didn’t work try the next method.
In this method , I recommend you to download the most stable version Dev C++ here ( wait 5 seconds for the download to begin ) and I personally tried this method using this version of Dev C++.
After downloading the above version of Dev C++ , download the below two important header files as these below header files mostly fixes all the errors with Dev C++ on Windows 8/8.1 and Windows 10 even and works fine.
Step 2 :
Click on the files to download the header files. These files are open source anyone can download them and edit them.
Step 3:
After downloading both the files , paste them into the following destination folder.

Start Dev-C++ on your compiler now you can work with Dev C++ seamlessly without any errors. This method mostly works and I’ve tested it. You won’t get g++ exception during compilation.

If the above solution doesn’t fix the problem you can download the updated setup which includes Latest Dev-C++ (32bit and 64bit). You canDowload Latest Dev-C++here(47MB) and comment the errors you face during this procedure.
