    If you mean that you want a string of a number, as in a string like "12345" then do as so:
    Code:
      #include <stdlib.h>
    
      char buffer[34];
      int i = 12345;
    
      itoa(i, buffer, 10);
    The third argument will be the base; 10 = decimal, 2 = binary, 16 = hex, etc. Hope this helps.

    hmm

    and if you want just to receive an simple output (int) and assign him in a char variable, you can do this, in this way:

    char num;
    scanf("%d",&num);

    All will be fine, but, if the input will be bigger than 255, you'll need to use int instead char.

    >>If you mean that you want a string of a number, as in a string like "12345" then do as so:
    But only if you have itoa which is not a standard function and not every compiler will support it. Or you could use sprintf, which is standard and more powerful.
    Code:
    #include <stdio.h>
    
    int main(void)
    {
      int num = 12345;
      char snum[6];
    
      sprintf(snum, "%d", num);
      printf("%s\n", snum);
    
      return 0;
    }
