how to create algorithm and flowchart by using averageof 100 students for particular examination

To create an algorithm and flowchart for calculating the average of 100 students' examination scores, you can follow these steps:

Algorithm:
1. Start the program.
2. Initialize a variable called "sum" as zero to store the sum of all the scores.
3. Initialize a counter variable "count" as zero to keep track of the number of students.
4. Start a loop that iterates 100 times (for each student):
a. Prompt the user to enter the examination score for a student.
b. Add the entered score to the "sum" variable.
c. Increment the "count" variable by 1.
5. Calculate the average by dividing the "sum" variable by 100.
6. Display the average.
7. End the program.

Flowchart:
A flowchart visually represents the steps and decisions in an algorithm. Here's a simplified representation of the flowchart for this algorithm:

```
Start
|
v
[Initialize variables]
|
v
[Loop for 100 students]
|
v
[Input score]
|
v
[Add score to sum]
|
v
[Increment count]
|
v
[Loop end?]
| |
| v
v |
[Calculate average]---
| |
v |
[Display average]
|
v
End
```

This flowchart illustrates a loop that repeats 100 times, taking input for scores, calculating the sum, incrementing the count, and finally calculating and displaying the average.

Keep in mind that flowcharts can be more complex depending on the specific requirements of your program, including error handling or additional calculations.
