while statement again!

[SilviaJamieson]

Hi everyone,

Did I do something wrong? I am curious as to why no-one has attempted to point me in the right direction??

I have to write a C program that finds the average of a list of 5 numbers using while-statement.
„ Use scanf function to read 5 numbers from keyboard
„ Use printf function to display the average of a list of numbers on the screen
„ After displaying the average value, the program should ask user if he/she wants to find the average of another list of numbers

I have downloaded many tutorials and i find them very difficult to follow, it is kind of like reading a foreign language, i know that most people are probably laughing thinking how simple this is, i will get there eventually!

Best wishes ……daisy :oops:
