Anybody of you got any idea what this "internal compiler error: Segmentation fault" means? I searched internet, but didn't get anything useful. Then I did my analysis. I found out something peculiar. The code that I am trying to compile is a file for unit testing one of our classes. …

Dude, this has hundreds of errors when I compiled. Either you post a proper code or point out which line of code concerns you.

Why can't you do something like this. [CODE] unsigned int mm; //holds the month unsigned int dd; //holds the day unsigned int yy; //holds the year unsigned int ordinal_day = 0; //holds your ordinal day number //define an array which holds the number of days in each month unsigned int …

what is your large number? which data type are you using to hold large numbers?

why is there no enclosing brackets for the lines under for loop? Is it intentionally missed out? From the logic under for-loop, I don't think so

A tricky way, may not be the best way. Here it is: [CODE]#include <iostream> using namespace std; int main() { int a[2] = {1,5}; long addr1 = (long)(&a[0]); long addr2 = (long)(&a[1]); cout<<(addr2 - addr1)<<endl; return 0; } [/CODE] take absolute value of addr2-addr1 inorder to avoid a negative answer.

Ok, if you want to retrieve the info at the last use "back" [CODE]a_student.assignments.back()[/CODE] If you want to retrieve from anywhere else using an index, use "at" [CODE]a_student.assignments.at(4)[/CODE] See this [URL="http://www.cplusplus.com/reference/stl/vector/"]link[/URL] for more info

at line 29 you are setting seconds back to 0. So it's an infinite loop. Use a different variable in for loop condition.

I didn't take the trouble in going through your entire code. But what sounds to me is that you have to use a static variable as ID. Initialize it to 1. increment it every time you add a patient.

You are passing the pointer by value. And you are swapping the copy of the actual pointers in swap() function. When it comes out from the function, the pointers' copies go out of scope and hence no swap happens. One solution is to pass the pointer by reference. Other solution …

[CODE]bool dayType::equalDay(const dayType& otherday) const { return (this->day == otherday.day); } [/CODE] "this" is the object with which you are calling equalDay(). You are comparing this's day and otherdays's day and returning the result.

I didn't try to understand what you are doing in your code. But, I see one mistake. Variables like digit10 which is of int type cannot hold such a big value. If int is of 4 bytes, it can go only till 2147483647 but digit10 is assigned with 68719476736.

I find lot of bugs in your code. 1. In the main function you are calling [B]createAndCount()[/B] without any arguments, but where as from the signature of the function, it is seen that it accepts an integer. 2. In [B]count()[/B] you are using a variable 'n' in the for loop. …

You can simply enter your input separated by spaces. It need not be \n character always. For cin>>i>>j; you can actually enter two numbers separated by space. Or, you want a space to be inserted when you press enter, and wait for the next input?
