How Write a program to calculate sum of numbers between 0 to 10 in ruby on the rail?

Answer 1

I don't specifically know Ruby on Rails, but usually (in most programming languages), to do this task you would define one variable for the sum, and one for a counter. You initialize the sum to zero, and then, in a loop, you (1) increment the counter (most languages specifically have a "for" loop for this), and (2) add the counter to the sum. Here is the pseudocode; it is NOT for a specific programming language, but it gives you the general idea; you should be able to adapt it to most programming languages:

sum = 0

for addend = 1 to 10

{

sum = sum + addend

}

output "Sum = ", sum

Note that you may also need to initialize the variables, depending on the language.
