Here is the code. I input 233
twice as the Variables g
and k
.
#include <iomanip>
#include <iostream>
using namespace std;
int main() {
int g, k;
cout << "type number :";
cin >> g;
cout << "your number : " << g << endl;
cout << "type another number: ";
cin >> k;
cout << "your number : " << k << endl;
int sum = g + k;
cout << "sum is :" << sum;
return 1;
}
why the terminal output type another number:
, then accept the input233
user passed in ,finally output the 5 spaces to the begging of the 4th line. Like this:
type number :233
your number : 233
type another number:233
your number : 233
sum is :466
instead of
the terminal output type another number:
, then accept the input 233
user passed in, finally output your number : 233
?
In my opinion, the terminal should be like this:
type number :233
your number : 233
type another number: 233
your number : 233
sum is :466
Please tell me why my expectation is wrong ,and introduce specifically why the C++ handles space in this way and any information or key mechanism about this.😄
Hey guys, I just finished my investigation about this little C++program on two platform.
My operating system: Windows10 Pro 22h2
Windows OS Builds: 19045.5247
My running platform: JetBrains CLion 2024.3.1 Pro
CLion toolchains:
Bundled MinGW Version 11.0 w64
Bundled CMake Version 3.30.5
Bundled GDB Version 15.2(all of them is CLion bundled)
Terminal: CLion built-in terminal
CMakeLists:
cmake_minimum_required(VERSION 3.30)
project(untitled)
set(CMAKE_CXX_STANDARD 23)
add_executable(untitled main.cpp)
Here is the keypoint: When I run this code in Visual Studio 2022(the newest version) on my PC, VS2022 terminal show the right expectaion like this:
type number :233
your number : 233
type another number: 233
your number : 233
sum is :466
Is that the error from MinGW?
But, when i change CLion toolchains from MinGW to Visual Studio, it still show the wrong output in the terminal bundled by CLion:
type another number:233
your number : 233
Maybe this situation can be reproduced now.😄
Inspired by previous answers and my extensive research, This problem has already solved. Thanks to all contributors!😄 The problem is from the platform CLion i used. We can solve it by this two url: here and here
