Chapter 3, Problem 6CP
Explanation of Solution
Given: The following expression:
if radius >= 0
{
area = radius * radius * PI;
cout << "The area for the circle of " << " radius " << radius << " is " << area;
}
To find: The possible mistake in the expression:
if radius >= 0
{
area = radius * radius * PI;
cout << "The area for the circle of " << " radius " << radius << " is " << area;
}
Solution:
The possible mistake or error in the code is that the condition of the ‘if’ statement is not enclosed within parenthesis, and the variables radius, area, and PI are not declared. In order to run the code correctly, the following code should be written:
// Includes header files
#include
// Includes header files

Write a code for craps game. Craps is a dice game in which the players make wagerson the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots,respectively. After the dice have come to rest, the sum of the spots on the two upward faces iscalculated. If the sum is 7 or 11 on the first throw, you win and play is over. If the sum is 2, 3or 12 on the first throw you lose and play is over. If the sum is 4, 5, 6, 8, 9 or 10 on the firstthrow, that sum becomes your “point.” To win, you must continue rolling the dice until you“make your point” (i.e., roll that same point value). You lose by rolling a 7 before making yourpoint(in python)
