instead, for each of the "else-if" statement. Or else, all income greater than 15000 will go into the first "else-if" scope because the compiler will compute (15000 < income) as 1 (true), and then compute (1 <= 44000) as true.
Alright, I will comment base on your latest codes, cos I don't really have time to go through all the posts. Also, I will skip removeAt() function at this moment and focus on the rest.
1. At the main function, you are still passing uninitialized variables "insertItem" and "index" by values to the functions (line 24 and 25). If you have no use for them, take them out from the parameters. Use local variables instead.
2. Line 140 should be this instead:
cout<<"After inserting the item at position "<<index<<", array
3. At line 144, according to your instruction at line 132, it should be the following instead:
numbers[index] = insertItem;
4. Still, if you perform point 3, you are only OVERWRITING the array item, not inserting it. If you are going to continue using integer array for insertion, there are 2 ways you can do about it:
a) Declare a large array size (say 100) initially, fill the first 12 with your numbers and leave the rest. When doing insertion at say position #2, first use a loop to "push back" all items from position #2 onwards, then write the new value at position #2. Something like this:
Is python really that good? Sorry I came from a C++ background, using C/C++ for more than 10 years but never touched on python before. Been hearing good things about python here.
thank you for your reply~ I know what you mean by CriticalSection,unfortunately my developing evironment is C,nothing to do with MFC(sorry for not mentioning it in the post). under pure C,the CriticalSection APIs is also available,as I know ,it is used to synchronize the operation between thread ,that is : within the process. what I want is to operate interprocessly.(sorry for not metioning this,either :P) that is : read_write lock between processes. Is there any version of free source around the www?
You can use CreateMutex() to create a named mutex. Then use WaitForSingleObject() to wait for the mutex, either for a fixed timing or infinitely. Then call ReleaseMutex() to release it.
Are you sure your program runs fine? At the first glance, there's so many errors in it:
1. Your main function is passing uninitialized variables' values like index and insertItem into removeAt() and insertAT() functions.
2. Inside insertAt() function, index and insertItem are treated as local variables. That's very bad programming. If you don't intend to pass values, you should simply declare those as local variables instead of parameters.
3. In insertAt() function, the variable item is neither initialized nor assigned any values, yet it is used at the end of the function inside the loop. This leads to some undefined behaviour.
4. You only check once for invalid user input. You should use a loop such that the program will always prompt the user for inputs after each invalid inputs.
5. You use insertItem for the item to be inserted, and index for the position to be inserted. Yet in the below code you never used the variable index! You should used it as the index of the array.
6. Even if you rectify for point number 5, it still doesn't achieve what you want. It merely overwrite the existing array item with the new item, instead of inserting the item into the position stated. To do what you want, all the subsequent array items must be pushed backwards. If you want to use integer array, then you need to manually "grows" the array to cater for the …
I believe you still need to do programming, especially when you are at an entry level software developer job. Software design and programming are closely related, and having strong programming skills provides a sound foundation for software design.
It really depends on your work nature and environment. If you are working with team members that are stationed overseas, or integrating with systems where their developers are not local, you would need a lot of communications. Also, we need to document our technical specifications and source codes so that other people can reference them, even if we no longer stay in the company.
It depends on your budget and your requirements. Do you want people to reserve online via internet, or is the software just keeping track of reservation status made through phone calls?
Welcome to Daniweb! I would advice you to learn about HTML first since you said you have no knowledge about it. It's just a markup language and would be very easy for you to pick up. After that, you can learn about some client-side scripting, which is also not difficult given your knowledge in VB.
