So I am trying to write a program that has 3 subcategories under the category section. the subcategories are donuts, drinks and chips
struct Inv
{
double sku;
char category[SIZE];
[Code].....
I have to make the subsections here so the user can choose the category.
For instance Code: int counter;
counter =0;
FILE *pfile;
pfile= fopen("g:myprog.txt" "w");
while (counter >100)
{ fprintf (case counter{something})}; how do I do this?
I have a batch of .pdf files (~1000) with names 001.pdf 002.pdf ...etc. Still pretty new to C, but would it be possible to write a program that would open a PDF, prompt a new name from user, and when entered, close the .pdf and open the next one in the list?

Code:

So it should copy test1 to test2. Now I created test1 in gedit. I just put one character "c" in it and closed it. And I ran the program. When I check sizes of test1 and test2 , using
ls -l
command, I see that test2 has 4 bytes and test1 has 2 bytes. So something strange is happening here. I just put a single character in test1, so shouldn't it show 1 byte ? And why test2 is showing 4 bytes ? I have Win XP on my laptop. And I use Ubuntu 12 inside VirtualBox. So this is Linux environment...

-Get the number of records and the numbers to store from the user.
-Save all the numbers in "all_numbers" file.
-Read each number and check whether it is odd or even.
-Store the odd numbers in odd_number file and even numbers in even_number file.
-Finally, print the numbers stored in odd_number and even_number files.
The output of the program will look like this.
How many records that you want to store :41
2
3
4
The data are written too the respective files.
The even numbers are 2 4
The odd numbers are 1 3

Write a program that reads data from a file (use the attached data file). These data are a student name and 3 test scores. The program should calculate the average of the 3 test scores, and display the name, 3 test scores, and the average to the monitor.
Useful tips:
a) Include the following header files: iostream, fstream, iomanip, and string
b) The name of the data file is “datafile.txt”, you need to save the file in the same folder of the source file.
c) use the manipulators (setw, setprecision, setfill, showpoint, fixed) to format the average with 1 digits after decimal point as following.
d) Use character ‘ ’ for tab.

write a program that will connect my laptop to my desktop unlike gotomypc.com. I want to have my desktop hooked up to a router and sends video and audio info to my laptop. At the same time my laptop will be sending it's keyboard and mouse. If there is an audio input from a microphone it will send that to the desktop. If the webcam needs to be used for something like Skype, it will send that to the desktop too. I think it would be faster for the laptop to process any flash drives, but it should be able to send that to the desktop too. Has a program like this already been created? Is C++ an optimal language to write the program in?
