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

here is code in C++.

#include

using namespace std;

//main function

int main ()

{

//declare variables

double total;

double avg, res;

int i, j;

/ / this loop to iterate over the Experiment

for (i=1; i<=3; i++)

{

total=0;

avg=0.0;

cout<<"Experiment "<
/ / take input of test result for each Experiment

for (j=1; j<=3; j++)

{

cout<<"Enter test result "<
cin>>res;

/ / calculate total of each Experiment

total=total+res;

}

//calculating average of each Experiment

avg=total/3;

/ / printing the output

cout<<"/nExperiment "<
}

}

Explanation:

Declare variables "total","res" and "avg" to store total of each expression, read test result and average of each Experiment. Outer loop run for each Experiment and take 3 test result, calculate their sum and find average. And then print the average of that Experiment. Similarly this happen for 3 time to take test result and print their average.

Output:

Experiment 1

Enter test result 1:10.1

Enter test result 2:20.8

Enter test result 3:33.4

Experiment 1 average: 21.4333

Experiment 2

Enter test result 1:23.4

Enter test result 2:84

Enter test result 3:54

Experiment 2 average: 53.8

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
