Using R, Create a while loop which starts x at 1, and prints x: “Are we there yet?” until x reaches 10. (Don’t forget to Increment x by 1 each while loop). To make things interesting, include the line readline(prompt = "Press [enter] to continue") after the print statement stated above. If x is an even number, print x: “Even Number Encountered” And go to the next iteration of the while loop (i.e. No readline – as above)

Answer #1

Hi,

If i have understood your question correctly, please find below the solution in R.

x <- 0
while(x < 10)
{
x <- x + 1
print(paste(x,"Are we there yet?"))
if((x %% 2) == 0)
{
print(paste(x,"Even Number Encountered"))

}
else
{
readline(prompt="Press [Enter] to continue")
}
  
}

OUTPUT:

[1] "1 Are we there yet?"
Press [Enter] to continue
[1] "2 Are we there yet?"
[1] "2 Even Number Encountered"
[1] "3 Are we there yet?"
Press [Enter] to continue
[1] "4 Are we there yet?"
[1] "4 Even Number Encountered"
[1] "5 Are we there yet?"
Press [Enter] to continue
[1] "6 Are we there yet?"
[1] "6 Even Number Encountered"
[1] "7 Are we there yet?"
Press [Enter] to continue
[1] "8 Are we there yet?"
[1] "8 Even Number Encountered"
[1] "9 Are we there yet?"
Press [Enter] to continue
[1] "10 Are we there yet?"
[1] "10 Even Number Encountered"

if i have understood your question correctly, when even number is encountered press enter to continue will not be displayed .are we there yet is printed for all 10 iterations.

Thanks,

Chandana

    Newton's Method in MATLAB During this module, we are going to use Newton's method to compute the root(s) of the function f(x) = x° + 3x² – 2x – 4 Since we need an initial approximation ('guess') of each root to use in Newton's method, let's plot the function f(x) to see many roots there are, and approximately where they lie. Exercise 1 Use MATLAB to create a plot of the function f(x) that clearly shows the locations of its...
