Design a flowchart or pseudocode for a program that accepts three numbers from a user and displays a message if the sum of any two numbers equals the third.

Write a pseudocode to determine the type of triangle, depending upon the value of the sides

Sure! Here's a pseudocode for the program you described:

1. Get input for three numbers, num1, num2, and num3, from the user.
2. Check if num1 + num2 is equal to num3. If true, display a message saying "The sum of num1 and num2 equals num3."
3. If step 2 is false, check if num1 + num3 is equal to num2. If true, display a message saying "The sum of num1 and num3 equals num2."
4. If step 3 is false, check if num2 + num3 is equal to num1. If true, display a message saying "The sum of num2 and num3 equals num1."
5. If none of the above conditions are true, display a message saying "No two numbers sum up to the third number."

And here's how it would look in the form of a flowchart:

```
start
input num1
input num2
input num3

if (num1 + num2 == num3) then
display "The sum of num1 and num2 equals num3."
else if (num1 + num3 == num2) then
display "The sum of num1 and num3 equals num2."
else if (num2 + num3 == num1) then
display "The sum of num2 and num3 equals num1."
else
display "No two numbers sum up to the third number."
end if

end
```

I hope this helps! Let me know if you have any further questions.

Sure! Here's an example of pseudocode for the program you described:

```
// 1. Accept three numbers from the user
input number1
input number2
input number3

// 2. Check if the sum of any two numbers equals the third
if (number1 + number2 = number3) or (number1 + number3 = number2) or (number2 + number3 = number1) then
display "The sum of two numbers equals the third."
else
display "No sum of two numbers equals the third."
end if
```

And here's an example of a flowchart for the program:

In both cases, the program first prompts the user to enter three numbers. It then checks if the sum of any two numbers is equal to the third number. If any of the conditions are true, it displays a message stating that the sum of two numbers equals the third. Otherwise, it displays a message stating that no sum of two numbers equals the third.

read n1,n2,n3

s1 = n1+n2
s2 = n1+n3
s3 = n2+n3
If (s1==n3) or (s2==n2) or (s3==n1) then message
