Question

[TeenyTig]

I'm so confused! My code won't work right. I need it to print out the login name and it won't do that. It just prints out the password again. How do I go about printing out the login name??


printf("\n\nPlease enter a login name: ");
gets(temp);

ERROR = 0;
for(i=0; i<4; i++)

if(strcmp(name[i], temp) == 0)
{
ERROR = 0;
break;
}
if (ERROR == 0)
{ Decrypt(name[i-1]);
printf("Username Found!\n");
printf("Username: ");
puts(name[i+1]);
printf("Password: ");
puts(name[i+3]);
}
else
printf("Invalid Login Name");
}

change these 3 lines

puts(name[i+1]);
printf("Password: ");
puts(name[i+3]);

to

puts(temp[i+1]);
printf("Password: ");
puts(temp[i+3]);

Well, I already tried that and it gives me warnings of 'puts' being of different formats. So, it didn't work right.

Hello,

- What is the type of name?
- I'm counting 5 brackets, perhaps one missing?

Can you give more complete code.

1. You're storing the password in the same array as the names, so the names will be overwritten.

2. Why not use standard string functions? Use strcpy for copying strings, strlen for determining the length, strncpy for copying just a part of a string etc.
