}
for everyone of my if else statements.
Also If there is a way to make all the info for city 1 and city 2 in 1 bit If Statement then output at the end. I would like to know how.
Another not We have not discussed Loops or anything farther then what i have in this code in class and I will get in trouble for using it.
