Answer to Question #311479 in C++ for Nobody

Question

User-defined function can be defined as a function written by the programmers to accomplish certain specific tasks.

(a) List down the FOUR (4) types of user-defined function.

(b) Write the function prototype for each of the following user-defined functions:

i. Function calcPower() that receives the voltage and current of type double. This function will return a value to calling function.

ii. Function DisplayWelcome() that does not receives any values and does not return a value.

M

iii. Function triangleArea() that receives the height and the base of a triangle of type float. This function will not return any value to calling function.

Answer 1

using namespace std;

	float Power = V*I;
	return(Power);

void DisplayWelcome(void)
{

void triangleArea(float h, float b)

	float Area = 0.5*h*b;
