Create an assignment statement that sets the value of the variable you created to store the value of all test grades added together to zero. You may refer to Table $6\mathrm{.}1$ in Chapter $6$ for examples. Create an input statement to input the value for the first test grade for the variable you created Create an algorithm that will obtain the test grade for three students, add the test grades together, calculate the average of the test grades, and output the average. Use a count$-$controlled loop to create the algorithm. Use the information from your answers to questions $3,4,$ and $5$ in the creation of your algorithm. Also use information and examples from Chapter $6$ and Chapter $7$ to help you create the algorithm $7.$ Create a test to check the algorithm that is in a format similar to the following
