#include<stdio.h>
#include<conio.h>
void strrcat(char *,char *);
void main()
{
char a[50],b[50];
int i;
clrscr();
printf("enter the string 1 :");
gets(a);
printf("enter the string 2 :");
gets(b);
strrcat(a,b);
gets(a);
getch();
}

void strrcat(char *a , char *b)
{
for(int i=0;*a!='\0';i++,a++);
for(int j=0;*b!='\0';j++,i++,b++,a++)
*a=*b;
*a='\0';
}
