Why is that the case?

After I have toggled two breakpoints in my program and tryna debug,  it just go all the way down and finish the program

Indeed, I have never seen once when it could!!

But dev-cpp works well, I just feel puzzled.
 
And here follows the info in debugger:

It looks like you try to debug a release-project.
Make sure the debug switch is set while compiling, if you use MinGW/gcc it's -g .

And please use code-tags, if you post log-output or sources to make it more readable.

Code

#include<iostream>
using namespace std;
int main()
{
    int n = 5;
    cout << "Hello world!"<<endl;
    cout << n << endl;
    return 0;
}

just a test program, but I fail to track anyway, it just go until the last line and no yellow triangle appears

yeah, i mean the breakpoints are not effective

Why do you ask questions in a forum, if you do not read the answers ?

Reread my previous post, everything you need is written there !
