Write a C++ program to get input of a data set of 14 double valu.pdf
- 1. Write a C++ program to get input of a data set of 14 double values (grades) from the standard input device (the keyboard), then calculate and report the sum and the mean of the data set, then the individual DEVIATION of each individual input with respect to the mean, the variance of the dataset, and finally the standard deviation of the data set. This problem requires you to integerate multiple things together: arrays, loops, functions. More specifically, you want to use loops to deal with input, save them to array, or calculate sum and individual deviation, and display results etc. in separate functions. A sample run. Please let me know how many grades you would like to input? 14 Input them one by one: 89 95 72 83 99 54 86 75 92 73 79 75 82 73.
