Answer:
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double side, height;
cout<<"Enter the length of one of the sides of the base: ";
cin>>side;
cout<<"Enter the height: ";
cin>>height;
double area = side * side;
double volume = area * height / 3;
cout<<"The area of the base of the pyramid is: "<<area<<endl;
cout<<"The height of the pyramid is: "<<height<<endl;
cout<<"The volume of the pyramid is: "<<fixed<<setprecision(2)<<volume<<endl;
return 0;
}
<u>Pseudocode:</u>
Declare side, height
Get side
Get height
Set area = side * side
Set volume = area * height / 3
Print area
Print height
Print volume
Explanation:
Include <iomanip> to have two decimal places
Declare the side and height
Ask the user to enter side and height
Calculate the base area, multiply side by side
Calculate the volume using the given formula
Print area, height and volume (use <em>fixed</em> and <em>setprecision(2)</em> to have two decimal places)
Answer:
The program displays 5 4 3 2 1 and then raises an Array Index Out Of Bounds Exception.
Explanation:
A sample of code output is attached.
The code snippet contain xMethod that takes an array and array length as argument.
In the given snippet, the array {1, 2, 3, 4, 5} and length (5) is passed as argument to the method.
First the method display the element of the array in reverse order
System.out.print(" " + x[length - 1]);
and then the method call itself again. This displays
5 from x[4]
4 from x[3]
3 from x[2]
2 from x[1]
1 from x[0]
but after displaying 1, when it tries to call the method again, an array index out of bound exception is thrown because it will try accessing an element from the array when it is already exhausted.
Answer:
The answer to this question is that none of the following will give syntax error.All of them will get executed.
(0 < num)&& (num <12)
0 < num <12
0 < num&& num < 12
num > 0&& num <12
There is no syntax error i have checked on the compiler also.But logically we take variable on the left side of the comparison operator and the value to the right of the operator.
