Define a character array and use strcpy() to copy a string into it. Print the string out by using a loop with a pointer to print out one character at a time. Initialize the pointer to the first element and...


Nice, computer science homework.
int main () { char str[]="this is my string";
//print our string forwards int i = 0; while(str[i]!="\0") { putchar( str[i] ); i++; }
//newline putchar('\n');
//print our string backwards int length = strlen(str); while(length--) { putchar( str[length] ); } }
I didn't test this to make sure it worked, but this is the general way of doing this. It looks like your professor wants you to use pointers. I used pointers here. Do you know how? Arrays are pointers with some syntactic sugar.
I wouldn't rely on sites like this to get answers to your homework. Even if you get the right answer, there's always the possibility of your CS professor finding this answer online and then making your future homework ten times harder.

I have a problem in sorting


If your using windows:
Open cmd.exe (program files>accessories>command prompt)
use the sort command in this syntax:

sort "path name and or file name"

you may also use file exports like this for example:

sort birthdays.txt > sorted birthdays.txt (single forward will write over old files and make new ones)
sort birthdays.txt >> sorted birthdays.txt (use double forwards to made amendments to the file)

the "/R" function will reverse the sort order, for example:

sort /R birthdays.txt


thats all, hope this helps. I cant do much else with the information given.

Can I get the asswer for the below questions


A book shop maintains the inventory of books that are being sold at the shop. The list has details like author, title, price, publisher and stock position. Whenever a customer wants a book, the sales person inputs the title and author and the system searches the list and displays a suitable message if it is not available. If it is available, the system displays the book details and requests for the number of copies required. If the copies are available, the total cost of the copies requested is displayed, otherwise the message ‘copies not in stock’ is displayed.
Design a system using a class called BOOKS with suitable member functions and constructors. Use new operator in constructors to allocate required memory space.

Vb6 source code is not compiling.


What the heck are you compiling it with that doesn't give a line number for that error? Pay attention to the titles of messageboxes! Perhaps noting what lines you changed from the original will give a clue to narrow it down, but I expect you addressed an object with a property (object.property) in a context that can't be expected to generate or use that property as you gave it. Moreover there are spaces in object names, it seems....
