Hi,
I want to write a code which takes an array of 20 characters and deletes all spaces between characters, it should leave only letters. For example:
input : d a n i w e b
I want...

And I tried the code in another compiler. It worked but as I see it gets numbers in decimal but I need to get numbers in hexadecimal...
Thanks...

Yes I surely added, I actually directly tried the example code in the cplusplus page you sent...

Although itoa function seems very useful, I couldn't use it, I use Ubuntu and gcc compiler. And when I try to compile I get this error:


What is the problem you think?
Thanks

Hi I want to write a program which reads a hexadecimal number and returns an decimal number.

I wrote that code(inspired by some code pieces from web):

#include <stdio.h>
int main()

Yeah I really understand now :) thank you very much :)

In this bold part you say the next read value will be interpreted as an integer but where is the next read value, isnt there only one read value in this code (sentence) ?

Thanks a lot!

can you tell me why I would ignore the read value with this " %*s"? I understood other parts, thank you very much...

I just can't understand what happens in the example there :




what do "i" variable and str[20] array do in this function?
Thanks!

Hi, I am expected to use sscanf function in a program, but I couldn't understand how it works. Can you explain it with an easy example?
Thanks
