String Concatenate Using Pointers

#include<stdio.h> 

int string_concatenate(char *a,char *b) 
{
 
    while(*a!='\0') 
    { 	
      a++; 
    } 
 
while( *b!='\0')
 { 
   *a = *b; 
   a++; 
   b++;
 } 	 
   *a='\0';
 
	 } 


void main() 
{  char s1[100], s2[100]; int l; 
   printf("\nEnter the First String : ");
   gets(s1);
   printf("\nEnter the Second String : ");
   gets(s2); 
   
   printf("\nThe concatenated string is: "); 
   string_concatenate(s1,s2); 
   puts(s1); 
}
