Does codeblock have a bug?

Question

I ran a pointer example both g++ compiler of ubuntu and codeblock. The results are Ox7fff1b6c9348 and 5 respectively. How can solve this problem? Thank you.

Answer 1

Please show your code. Even without seeing the code, I doubt that Code Blocks has a bug that is so severe that pointers are arbitrarily dereferenced. So there's probably something wrong with your code

Answer 2

Never use x = ++x or something like that. The syntax is wrong. In general, never change the value of a variable more than once in the same statement, so avoid expressions like x -= x--, x = x++ + ++x etc.

++x increases x by one. What x = ++x does is undefined. I don't know if that's the only issue with your code, but undefined behavior could explain why you get different outputs in different IDEs.

#include<iostream>
using namespace std;
int main(){
int *p = new int;
*p=10;
int x1,x2,y1,y2,sum;
x1=5;
x2=5;
x1=x1++;
y1=x1;
x2=++x2;
y2=x2;
cout << &y1 <<","<<y2 <<";"<<p<<endl;
cout<<sizeof(char)<<endl;
cout<<sizeof(double)<<endl;
}

But first I ran without pointers. I noticed if the program changes, run function of codeblock do not build it again. After I pressed build and run button, it gave correct results. Thank you.
