if(gender='M' && age>=45 || gender='F' && age>=40)

If you're going to chain your logical operations like this, you need to use parentheses, and the == operator to test for equality:

if( ((gender=='M') && (age>=45)) || ((gender=='F') && (age>=40))

Look through your code and replace the other erroneous uses of = with ==.

You don't need extra parentheses but they can help readability.

In this case, not using the parentheses caused a compilation error, although interestingly a compilation error that also would not have happened had the == operator been used. Ironically, the poor form (lack of parentheses) showed up the logical error (assignment instead of equality-testing).

Not if he replace = with ==.
