Code Select

[/list]int main()
{

   for(int i=0;i<=10;i++)
    {
        printf("i=%d",i);
    }
    return 0;
}

If i want to start debug after n  iteration of the loop .
From above code . Suppose i want to start debug when i=7.
When i enter  i=7 in the "Break when expression is true" box .I got the endless loop.
How to fix this ?

Use i==7 or i>=7 for example?
You have to use C/C++ conditional in there, not assignments.

When i use  i==7 or i>=7  in example .It start debug at i=0  not start at i=7 .

Then you'll have to post the full log from the debugger. You have to enable it in the settings of the debugger.
