how to write flowchart find the maximum,minimum,sum and average of 3 numbers
Here is a possible flowchart for finding the maximum, minimum, sum and average of 3 numbers:
```
start
|
↓
input number1
|
↓
input number2
|
↓
input number3
|
↓
if number1 > number2 and number1 > number3 then
| max = number1
else if number2 > number1 and number2 > number3 then
| max = number2
else
| max = number3
end if
|
↓
if number1 < number2 and number1 < number3 then
| min = number1
else if number2 < number1 and number2 < number3 then
| min = number2
else
| min = number3
end if
|
↓
sum = number1 + number2 + number3
|
↓
average = sum / 3
|
↓
display max, min, sum and average
|
↓
stop
```
This flowchart assumes that the input numbers are valid and non-negative. It uses conditional statements to determine the maximum and minimum values among the three numbers, and then calculates the sum and average of all three numbers. Finally, it displays the results.
To write a flowchart to find the maximum, minimum, sum, and average of three numbers, follow these steps:
1. Start: Begin the flowchart.
2. Input: Prompt the user to enter the three numbers (A, B, and C).
3. Initialize variables: Set the maximum and minimum variables equal to the first number (A) and set the sum variable equal to zero.
4. Compare the numbers: Compare the first number (A) with the second number (B). If B is greater than the maximum variable, set the maximum variable equal to B. If B is smaller than the minimum variable, set the minimum variable equal to B. Add B to the sum variable.
5. Compare the numbers: Compare the third number (C) with the maximum and minimum variables. If C is greater than the maximum variable, set the maximum variable equal to C. If C is smaller than the minimum variable, set the minimum variable equal to C. Add C to the sum variable.
6. Calculate the average: Divide the sum variable by 3 (since there are three numbers) and store the result in the average variable.
7. Output: Display the maximum, minimum, sum, and average variables.
8. End: End the flowchart.
Note: You can use the appropriate flowchart symbols to represent each step in the flowchart.
