4. 
   
5. <LI class=li1>#include<iostream.h>
6. 
   
7. <LI class=li1>#include<stdlib.H>
8. 
   
9. <LI class=li2>void main(void)

11. <LI class=li1>{
12. 
    
13. <LI class=li1> clrscr();
14. 
    
15. <LI class=li1> char a[3]
16. 
    
17. <LI class=li1> //cout<<"ent int "<<endl;
18. 
    
19. <LI class=li2> //cin<<a;
20. 
    
21. <LI class=li1> atoi(a)
