Question

4. Show your output that only even numbers from 80 to 115 get printed. Hint. You can use modulo (%%) in Chapter 1. Even numbers have the remainder 0 after division of the number by 2. You start with the following code for a) and b): number <- 80

a) Use repeat loop

b) Use while loop You start with the following code for c): number <- seq(from = 80, to = 115)

c) [ Use for loop

Answer 1

a) Use repeat loop

number <- 80
repeat {
if (number %% 2 == 0){
print(number)
}
number = number + 1
if (number == 115){
break
}
}

b) Use while loop

#R version 3.3.2
  
number <- 80
while (number < 115) {
if(number %% 2 ==0)
print(number)
number = number+1
}

c) Use for loop

#R version 3.3.2
  
number <- seq(from = 80, to = 115)
for (val in number) {
if(val %% 2 == 0)
print(val)
}

OUTPUT:
