Thread: Shorter way to convert number to txt

guys,
I'm currently working on this piece of work where i'm required to write a c code that will allow the user to input a 4 interger then the code works to change it to word form as in eg.
user input>5742
output> Five Seven Four Two

i've managed to get the first part of the code where I need to break it down to work using

Code:

 
  printf("Enter a number> ");
     scanf("%d", &interger);
     printf("\n\n");
     
    
     th = interger / 1000;
     
     hun = interger / 100;
     hun %= 10;
     
     ten = interger / 10;
     ten %= 10;
     
     unit = interger%10;

then if i wanted the program to show it in words i could very much use switch but the code would be very long as i'd need to make switches for every part of the integer so i was wondering is there any way that i can do it without using arrays as i've not gotten to that part yet?

Code:

 
<include stdio.h>
int name(int x)
{
switch(x)
{case 1:
printf("one ");break;
case 2:
printf("two ");break;
case 3:
printf("three ");break;
/*make it until 0*/
}
int main(){
  printf("Enter a number> ");
     scanf("%d", &interger);
     printf("\n\n");
     
    
     th = interger / 1000;
     hun = (interger%1000) / 100;
     ten = (hun%100)/ 10;
     unit = (ten%10);
name(th);name(hun);name(ten);name(unit);//it would print all of them
}

may be like this...
or you can put this
th = interger / 1000;
hun = (interger%1000) / 100;
ten = (hun%100)/ 10;
unit = (ten%10);

in a function.. so you just sent your integer to that function..

owh sorry.. I forgot to "return 0" at the function.. hehehe..
or you can also make the function char... so you can return char..

thanx! tatz exactly the way i wanted to do but didnt know how to! thanx thanx thanx! and i'd be honest i don't really understand the way these functions work like where did (int x) came from i refer to the X here as in :s and how does the int x works lol

so ure saying basically i can use any int as long as i name int x and not some definite name? like x is the wildcard here?

yapp... when you declare x as int in that function, it would use if you call it inside that function..
so, in other function it was unknown variable...
like x is only for name function(int name(int x))

but in main function, x is unknown, until you declare it.. but the value isn't same.. and the type can be different(as you want)
