I assume you have done the steps to acquire the marks and calculate their averages...
Gghhh
Draw a flow chart to calculate total and average of a student
To draw a flowchart to display the total and average of math marks of 50 students, you can follow these steps:
1. Start: Begin the flowchart by using a "Start" symbol.
2. Initialize Variables: Declare and initialize variables to store the total and average marks. Use the appropriate symbol to represent the assignment of values to the variables.
3. Input Marks: Use an input symbol to represent the input of math marks for each student. Since you have 50 students, you will need to repeat this step 50 times.
4. Update Total: Use a process symbol to add the marks of each student to the total variable. Connect the input symbol to the process symbol with an arrow.
5. Update Counter: Use a process symbol to increment a counter variable by 1 for each student. Connect the process symbol to itself with a loop arrow pointing back to recalculate the total and counter variables.
6. Conditional Check: Use a decision symbol to check if the counter variable equals 50. If it does, proceed to the next step. If it doesn't, loop back to the input symbol.
7. Calculate Average: Use a process symbol to calculate the average by dividing the total by 50 (or the counter variable). Connect the decision symbol to the process symbol with arrows.
8. Display Total: Use an output symbol to display the total marks.
9. Display Average: Use an output symbol to display the average marks.
10. End: End the flowchart with an "End" symbol.
Remember to use appropriate symbols for the different steps and connect them with arrows to indicate the flow of the program. Use rectangles for processes, parallelograms for input/output, diamonds for decisions, and the appropriate arrowhead symbols to indicate the direction of flow.
