class X

def main
trace 3 + 5
print 3 + 5
trace .add(3, 5)

def add(a as int, b as int) as int
return a + b

Sounds like you're new to programming. If so, you are probably better off starting with the Python language and a book like "Python Programming for the Absolute Beginner".

You can get input with Console.readLine and you can change it from a string to an int with either int.parse or int.tryParse. You can search for these on google to see examples in C# or VB, or to read their reference documentation.

i have read the last posts and i have a problem about the Console.readline, i've also checked the reference of C# and VB
and it just gave me confusion because they have different syntax and it gave me errors. can you share me a cobra code about adding numbers with the use of Console.readline, int.Parse etc. so that it will ask the user on what numbers he/she wants to add? thank you so much

class Add

def main
print 'Enter two numbers:'
x = Console.readLine
y = Console.readLine
print 'sum is', int.parse(x) + int.parse(y)
print 'done.'

Code: Select all
Enter two numbers:
3
4
sum is 7
done.

Other than giving you the code to do what you want
what would you have needed/wanted to see (in compiler, doc, website,..)
to make it easy/easier for you to work out what you needed to do yourself ??
