umm, ok wait

Answer 22

You are trying to much ;)

The computer should do all the boring work for you.
I made a working solution (not perfect). Study it and try to write a similar one.
https://ideone.com/eCETiq

#include <stdio.h>

char encode(char number)
{
char letters [] = "XCOMPUTERS";
char numbers [] = "0123456789";

int index = 0;

while (numbers[index] && number != numbers[index])
++index;

if (index == 10)
return number;
else
return letters[index];
}

int main(void)
{
char in;

while ((in = getchar()) != -1)
putchar(encode(in));

return 0;
}

Answer 23

O_O , ok sir I'll try this one

Answer 24

wow, it really worked... but... I don't know some of the data types it used... such as getchar... :(

Answer 25

getchar() is a function that returns each caracter you typed in the console.
When there are no more available caracters it return -1.

So by looping over getchar() while it's not equal to -1 you get each caracter from the console individually.

Answer 26

ooooh... :D

Answer 27

thanks. ! :)

Answer 28

Yw :)

Answer 29

I made some changes. It should now better according to the specification.
https://ideone.com/eCETiq

#include <stdio.h>

#define MAX_SIZE 20

void encode(char* number)
{
char letters [] = "XCOMPUTERS";
char numbers [] = "0123456789";
int index;

while (*number)
{
index = 0;

while (numbers[index] && *number != numbers[index])
++index;

if (index == 10)
putchar(*number);
else
putchar(letters[index]);

++number;
}
}

int main(void)
{
char in_string [MAX_SIZE];

puts("Enter a number: ");

if (fgets (in_string, MAX_SIZE, stdin) != NULL)
encode(in_string);


return 0;
}
