If statement question

[QM168]

Use three separate if() statements for the tests (one for each possible hypotenuse). Remember if you don't find a right triangle in any of the three if() statements for a fourth if() statement to print a message saying the sides don't form a right triangle. Do not use if-else() for this, just four if() statements.
Your fourth if() statement may not test the sides entered by the user. You must
REMEMBER if you have seen a right triangle or not.

Could anyone explain what does the fourth statement mean and give me a hint?

I have no idea what should I do now because of the restriction for the fourth if statement.

Another question is when I declared the variables as integer， the calculation for the pow(x,y) was incorrect. For example, the result for 5 square became 24 instead of 25. Does this mean only float is working for the pow() function?

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
    float side1, side2, side3, hy1, hy2, hy3;

    cout << "Enter the length of the three sides: " << flush;
    cin  >> side1;
    cin  >> side2;
    cin  >> side3;
    cout << endl;

    side1 = pow (side1, 2);
    side2 = pow (side2, 2);
    side3 = pow (side3, 2);

    hy1 = side1 + side2;
    hy2 = side2 + side3;
    hy3 = side1 + side3;

    if (side1 == hy2)
    {
        cout << "It is a right triangle.";
    }
    if (side2 == hy3)
    {
        cout << "It is a right triangle.";
    }
    if (side3 == hy1)
    {
        cout << "It is a right triangle.";
    }
    if ( )
    // I'm stuck here since I can't use the user input as the test condition.
    {

Is this all the code you have if not you will need to show more for help

[xenovia12]

you can actually use the user input as the test condition.

What is the different between these statements?

    if (side1 == hy2)
    {
        cout << "It is a right triangle.";
    }
    if (side2 == hy3)
    {
        cout << "It is a right triangle.";
    }
    if (side3 == hy1)
    {
        cout << "It is a right triangle.";
    }

    if (side1 == hy2)
    {
        cout << "It is a right triangle.";
        if (side2 == hy3)
        {
            cout << "It is a right triangle.";
            if (side3 == hy1)
            {
                cout << "It is a right triangle.";
            }
        }
    }

Unfortunately, I not allowed to use the user input as test condition.

Can you use a bool variable to "remember" that a rt. triangle has been found?

bool isRtTri = false;
if (side1 == hy2)
    {
        isRtTri = true;
    }
// same with others
if ( isRtTri ) cout << "It is a right triangle.";

[QM168]

Yeah, it works.
I learned a new function today.
Thank you very much! Appreciated!

What is the different between these statements?

in the first one.

only one will be executed if you run the program.


in the second

there is a possibilty that all statements will be executed if you run the program
