Carefully do the calculations of the following C++ program statements and provide your calculations line by line in the spaces provided below each question. Where appropriate substitute values for the variables in the questions and for testn. Label the data type of each answer box and write in the box the value of the identifier on the box. You must show your calculations. The ASCII Table is on page 11 of your Textbook. For int testn = 10; do 2., 3. and 4. 1. (1 point) int k; k = 0.9009; Show your step-by-step calculation as it is done in the textbook: 2.
