Function cannot modify the input parameters.-Output parameters of the function are the area and height of the triangle. Function must calculate and modify these 2 parameters.-Function must have a boolean return (success or failure) to indicate whether the calculation is successful or not.-This function returns true if both base and hypotenuse are not negative (0 base is valid). There is also a validation rule that the following expression cannot be negative to avoid calculation of square root of a negative number.If validation fails then the function returns false and skips all calculations. -The function isoscelesTriangleHeightAndArea() should Not use any "cin" or "cout". Only the main() function will contain "cin" and "cout".-The main() function calls the function in a loop until the user enters 0 0. These are the "Sentinel" values that stop the loop (chapter 5). If only one input is 0 and the other input is positive, the loop will keep going.-Use variable name base and hypotenus, not a and b.The following is a basic simple code without loop to test your function:#include #include // Function prototype// -----------int main(){ double base = 2.5, hypotenuse = 3, height, area; bool success = isoscelesTriangleHeightAndArea(base, hypotenuse, height, area); if (success) { cout << "Triangle height is " << height << endl; cout << "Triangle area is " << area << endl; } else cout << "Invalid Input!" << endl; // Expected output is: // Triangle height is 2.72718 // Triangle area is 3.40897}Output is:Triangle height is 2.72718Triangle area is 3.40897You can use this web calculator here to verify results:https://keisan.casio.com/exec/system/1273850202It is not required that you have to copy and paste the above code to your code for submission. But the code gives you an excellent guide of how to write the function prototype so that the test code above works correctly. If your function code does not work with the above given main() code, your score will be very low because the function is incorrect. The result of the function call is used in main() to decide what to display for the output: if the return value is true then it means the calculation result is stored in area and height, and if false it means that the input parameters base and hypotenuse are invalid.After using the simple test code above, write code in main() to accept multiple base and hypotenuse inputs and display the results by writing a Sentinel loop (chapter 5, lecture 5/23/22) that runs until the user enters 0 and 0 for the 2 inputs.Note:Do not use an infinite loop as a sentinel loop.Do not use "break" statements.A good sentinel loop does not use an extra "if" statement inside loop to check for the sentinel value 0 and 0.If the sentinel loop is correct, the function is NOT called when input is 0 and 0 because these values will make the loop stop.There is no need to control the number of decimal digits in the resultsThe output text and results should be aligned nicely as seen in the following samples.Write the function prototype before main() and write the full function definition after main().Output samples

The program is an illustration of C++ functions;Functions are program statements that are executed when evokedThe C++ programThe program in C++, where comments are used to explain each action is as follows:#include &lt;iostream&gt;#include &lt;cmath&gt;using namespace std;//This defines the boolean methodbool isoscelesTriangleHeightAndArea(double base, double hypotenuse, double height, double area) { //This checks for invalid base and height if(base &lt; 0 || hypotenuse &lt; 0){ return false; } //This returns true if base and height are valid return true;}//The main begins hereint main(){ //This initializes the variables double base, hypotenuse, height, area; //This gets input for base and hypotenuse cout&lt;&lt;"Base: "; cin&gt;&gt;base; cout&lt;&lt;"Hypotenuse: "; cin&gt;&gt;hypotenuse; //The calls the boolean method bool success = isoscelesTriangleHeightAndArea(base, hypotenuse, height, area); //If success is True while (success){ //This calculates height height = sqrt(hypotenuse*hypotenuse - (base/2) * (base/2)); //This calculates area area = 0.5 * base * height; //This prints height cout &lt;&lt; "Triangle height is " &lt;&lt; height &lt;&lt; endl; //This prints area cout &lt;&lt; "Triangle area is " &lt;&lt; area &lt;&lt; endl; //This gets input for base and hypotenuse cout&lt;&lt;"Base: "; cin&gt;&gt;base; cout&lt;&lt;"Hypotenuse: "; cin&gt;&gt;hypotenuse; bool success = isoscelesTriangleHeightAndArea(base, hypotenuse, height, area); } cout &lt;&lt; "Invalid Input!" &lt;&lt; endl;}Read more about C++ programs at:https://brainly.com/question/24833629#SPJ1
