Answer to Question #302406 in C++ for Imzi

Question

Consider the following statements:

int num1, num2, num3;

double length, width, height;

double volume;

num1 = 6;

num2 = 7;

num3 = 4;

length = 6.2;

width = 2.3;

height = 3.4 and the function prototype: double box(double, double, double);

Which of the following statements are valid or invalid?

a. volume = box(length, width, height);

b. volume = box(length, 3.8, height);

c. cout << box(num1, num3, num2) << endl;

d. cout << box(length, width, 7.0) << endl;

e. volume = box(length, num1, height);

f. cout << box(6.2, , height) << endl;

g. volume = box(length + width, height);

h. volume = box(num1, num2 + num3);

Answer 1

int num1, num2, num3;
double length, width, height;
double volume;


num1 = 6;
num2 = 7;
num3 = 4;


length = 6.2;
width = 2.3;
height = 3.4 and the function prototype: 


double box(double, double, double);


Which of the following statements are valid or invalid?
a. volume = box(length, width, height);			--> VALID
b. volume = box(length, 3.8, height);			--> VALID
c. cout << box(num1, num3, num2) << endl;		--> VALID
d. cout << box(length, width, 7.0) << endl;		--> VALID
e. volume = box(length, num1, height);			--> Valid
f. cout << box(6.2, , height) << endl;			--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
g. volume = box(length + width, height);		--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
h. volume = box(num1, num2 + num3);				--> Invalid as the function double box(double, double, double) requires 3 arguments to be passed
