what is.....

-----------------------------------

just wondering i am completly lost with this question i have for  home work
could someone explain what i have to do NOT DO IT FOR ME

the question...

Write a program that will ask the user to
enter an integer. Your program should
check to see if the user entered a valid
integer and output an appropriate
message depending on whether the user
correctly entered an integer or not.
Hint: Review the strintok function




so just wondering what this is asking (in a dumbed down version) :mrgreen: 
 :canada:  :mrgreen:   :P  8-)

It's checking to make sure the user did indeed enter a number. If a letter is entered, it will say 'no, you did not enter a number', while if a number is entered, it will say 'yes, you did enter a number'. 

Hints: Strintok- will check if the input can be converted to an integer.
         Strint- will convert the string to an integer.

This is useful as is stops your programs from crashing due to users entering a letter when asked for an int/real.

1) Name the topic of your post something better than "what is..."
2) If the teacher tells you to use a certain function, look it up in the help menu first and try to firgure out how to use for yourself
3) For the solution you put, if you enter an integer the first time around, you then you get stuck in a never ending loop.
4) There is alot simpler way of doing this.
5) Your suppose to use the strintok function not strrealok, even though they do a similare thing.
6) If you enter an integer right away your still being rude to the user with the last line even though they didn't do anything wrong.
