[C language help] recursive without return to add in the return of the difference?-CodePudding

 # include & lt; Stdio. H>

#include  
/* 
Function purpose: converting the input integer character 
*/
Void trans (int n) 
{

If ((n/10)!=0) 
{
Trans (n/10); 483//input, output without return output 483, plus the return 4 
} 


Putchar (n % 10 + '0'); 
} 

Void main () 
{
Printf (" hw 7.17 \ n "); 
int n; 
Printf (" do enter an interger: \ n "); 
The scanf (" % d ", & amp; N); 
If (n> 0) 
{

Trans (n); 
} 
If (n<0) 
{
Putchar (' - '); 

Int abs_n=abs (n); 
Trans (abs_n); 
} 


}

How is this to return a responsibility excuse me? It is best to something about execution, thank you!
