This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, Analysis, , Design(program design, pseudocode), Test Plan, and implementation with C code. The example provided uses sequential, repetition statements and nested repetition statements.

Program Description:
This program will calculate the average of 3 exams for 5 students. The program will ask the user to enter 5 student names. For each of the students, the program will ask for 3 exam scores. The student name and the average exam score for each student will be calculated and printed.

The program will consist of two loops. An outer loop for each student and an inner loop for the exams of each student. I will define one String to store student name: StudentName.

I will define three Float variables: Examvalue, Sum, Avg to store exam values, the sum of the exams, and the average of the exams.

The sum will be calculated by this formula: Sum = Sum + Examvalue

For example, if the first value entered was 80.0 and second was 90.0 and the third exam was 100.0: sum = sum + Examvalue = 0.0 + 80.0

sum = 80.0 + 90.0 = 170.0

sum = 170.0 + 100.0 = 270.0

Avg is then calculated as: Avg = sum/3.0

For example 270.0/3.0 = 90.0

A nested repetition loop can be used to loop through each of the 5 students and each of the 3 exams: For (students=0; students <5; students++)

For (exams=0;exams<3;exams++) End For

End For

Sum values will need to be reset for each student to ensure only one student data is used for calculations each time.
