CHAPTER 1 1 INTRODUCTION TO PROGRAMMING 22 • We are now going to make simple modications to this program so that it is able to average the weight of three people Do the following: • Within the variables area, change the variable names for age1 and age2 to weight1 and weight2 Add another variable of integer data type with the identier name of weight3 • The input area has... prompts and requests for data from the user They are paired up  a prompt and getting data from the keyboard We need to modify the prompt to ask for weight instead of age We need to change the variable name from age1 to weight1 Do this for the second pair that prompts and gets the second data item Create a third pair that prompts and gets the third data item • The process area has only one line of code and...
