Question

2. 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

below is the code the program specified in the question.

$ sudo apt-get install libreadline-dev

the above command should be executed in the terminal if it shows error for #include<readline/readline.h>, to install that library.

$ gcc -o print print.c -lreadline

the above should be executed to compile the file, for example 'print.c' is the name of the file, '-lreadline' tells the gcc compiler to link the 'readline library' or else it will show error.
