num = as.integer(readline(prompt="Enter a number: ")) if((num %% 2) == 0) { print(paste(num,"is Even")) } else { print(paste(num,"is Odd")) } Output 1 Store it in some variable say N. Run a loop from 1 to N, increment loop counter by 1 in each iteration. sprintf("I want to print this number: %i", number) #[1] "I want to print this number: 64" or paste0.

1. Code: x <- 50; c(1:(x*2))[c(1:(x*2))%%2 != 0] Take 2 works .
I actually wrote it at church from my phone so couldn't actually check it .
But if the answer is in fraction that means the number is incompletely divisable by 2, the number is odd.
If L or R is odd, then the count of odd number will be N/2 + 1 and even numbers = N – countofOdd. Also %% is modulo so if we're doing x %% 2 then if we want to find odd numbers we want this to be equal to 1 - whereas you're only grabbing the ones that are less than 1. Logic to print odd numbers is similar to logic to print even numbers.
