Write a program to calculate average result for three experiments. Each experiment has three sets of test result and the user is required to enter all 3 results manually. Using nested loop structure to compute and display the average of the test results for each experiment. The sample program run is as below. Experiment 1 Enter test result 1: 10.1 Enter test result 2: 20.8 Enter test result 3: 33.4 Experiment 1 average: 21.43 Experiment 2 Enter test result 1: 23.4 Enter test result 2: 84 Enter test result 3: 54 Experiment 2 average: 53.80 Experiment 3 Enter test result 1: 56.77 Enter test result 2: 65.15 Enter test result 3: 32.01 Experiment 3 average: 51.31 Press any key to continue
