Error: expected primary expression and ; before else

[dragonfly22]

Hi! I am getting this Error: expected primary expression and ; before else on line 77. For the life of me I can't see it. Can anyone please help me out?

You would probably be able to see these problems better if you used a consistent indent style.

Compiling the above code I get these errors:

In function ‘int main()’:|
main.cpp|77|error: ‘else’ without a previous ‘if’|
main.cpp|80|error: expected ‘;’ before ‘haveDiscount’|
||=== Build finished: 2 errors, 0 warnings ===|

You seem to have a mismatch between the number of your if statements and your else statements. Also line 79 seems to be missing something.

Thx for the help. I tried to seperate the if/else statements, now i get an error: expected : before cout

[dwks]

Post your latest code. If your error is "expected `;' before cout", then look on the previous line and see if it's missing a semicolon. Also look a few lines earlier on, certain kinds of syntax errors (especially missing curly braces) don't cause the compiler to complain right away; it will keep going and choke later on.

[iMalc]

You can't have two else's to an if-statement because each else is like saying "and in all other cases do this".
else-if on the other hand simply allows you to look at a specific case which has not yet been addressed.

Thank you for the help. I printed it out so I could see better and I did leave out a curly brace. Spent too hours looking at it on computer.
I do appreciate it!!
