===== CS 111 - Week 8 Labs - 2024-10-18 ===== ===== TODAY WE WILL: ===== * announcements/prep for next class * oh yeah: another C++ compound expression style: parentheses! * review clicker questions * Week 8 Lab Exercise ===== * Watch for class e-mails when Homework 7 is available ===== C++ and PARENTHESES (really another kind of compound expression!) ===== * ALSO NOTE: NOW you can use parentheses more similarly to the way you do in Math! Another compound expression in C++ is, you can put parentheses around ANY expression! 3 (3) ((3)) (((((3))))) (3 + 5) (3 + 5) * 6 etc.! * and like in Math's PEMDAS, parentheses let you specify to do one operation before another -- (3 + 5) * 6 // that is 8 * 6 or 48 3 + (5 * 6) // that is 3 + 30 or 33 * hey, what is 3 + 5 * 6 (if no parentheses?) C++ decides based on operator precedence! (I'll link a chart of C++ operator precedence with these notes!) * does have higher precedence than +, so 3 + 5 * 6 will have the value 33, BUT when in doubt, use parentheses to make this clear to you AND all future readers!!!
