Can I have multiple conditions for a single if statement?

Question

for example, I want to have a program where the person enters their birth month, date and year. I want an if-statement where if the month is <=12, date is <=31 and year is <=2016 it executes a code, but if else it produces an error message. I can't figure out how to make it all one if statement, do I have to use nested if statements for it to work? seems way too complicated that way.

Thanks!

Answer 1

you can simply use && to link multiple statements.
put in pseudo:
if ( day <= 31 && month <= 12 && year <= 2016)

&& is not the only operator
I'd recommend reading a short guide on Logical Operators ;)
