 # include & lt; Conio. H> 
#include  
Char pw [40]. 
Int I, ch. 
The FILE * f; 
Void main () {
Cprintf (" \ r \ nPassword: "); 
i=0; Pw [I]=0; 
While (1) {
Ch=getch (); 
If (ch==13 | | i>=39) break; 
The switch (ch) {
Case of 27: 
Cprintf (" 40 \ rPassword: % s ", ""); 
Cprintf (" \ rPassword: "); 
i=0; Pw [I]=0; 
break; 
Case 8: 
If (i> 0 {
i--; 
Pw [I]=0; 
Cprintf (" b \ \ b ");

break; 
Default:
