The error message already told what is the problem: just read it and check the code that it points out, in this case the else statement: that particular line is incorrect and needs fixing.

GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

scanf("%p" , &password); // should be %d for integer values

if(password=12345); // should be '==' for comparison test
{
printf("Your password is correct");
}

if else(password!=12345); // Removed the 'if', this is a continuation of the previous if statement

Also remove the semicolons following the right parens.

:doh:

I mean the right parens on the lines with ifs. The one on this line :

if(password=12345);

Will cause the printf to always execute.

I know, hence my :doh: , indicating my stupidity.

if else(password!=12345);

You need to learn better the if-else structure.

#include int main() { float number = 123456; int pass; printf("Please enter your password:\n"); scanf("%d",&pass); if (pass==number) { printf("Your password is correct.\n"); } else { printf("Your password is incorrect.\n"); } } i already write the program but i dont know how to make a prompted to re enter a password if i enter a wrong password..i really dont know..and i hope u can help me..

You do it be creating a loop, using a do, while or for statement. In pseudo code something like:

Set a retry count
While retry is not zero
Check password
If password is correct
Then break
Else
retry = retry - 1
If retry is zero
Then display error message
End While

See if you can turn that into C code.

if (pass==number)

Comparing an int to a float will rarely, if ever, work.

To continue the prompting until the correct password is entered, you'll need to use a loop. Something like:

do
{
...
} while (password != 12345);
