Please give me the code in C

Description: This assignment is to write a program to read unknown number of scores (double type) from the keyboard and calculate the sum and average of the scores. The program will repeatedly read positive scores until it reads a non-positive number, such as 0 or negative values. After reading the non-positive score, the program should output the sum and the average to the screen. Make sure the last input will not be part of the result. For example, if the user enters -12 to quit (as below), then -12 should not be part of the calculation. You don't need to use an array to store all the scores (we haven't learned it so far, but most importantly, it is not necessary!). Use variables to store the sum and number of scores as you read (read the textbook if you don't know how to do it!), and calculate the average after the user enters the non- positive value. Program Output: >run Enter a positive score (0 or negative to quit): 90.1 Enter a positive score (0 or negative to quit) 92 Enter a positive score (0 or negative to quit): 93.5 Enter a positive score (0 or negative to quit) -12 The sum is: 275.60, average is: 91.87 If no one invalid input at all, then output "No sum and average calculated! " with a new line ore quit the program. rur Enter a positive score (0 or negative to quit): -12 No sum and average calculatedi
