Hi, I'm new to programming and I'm doing a course in uni. I'm currently using "Dev-C++". I've been away on holidays and haven't been able to grasp the work we're doing now. I would really appreciate it if any of you C++ programming geniuses helped me with my work as I'm in a troubling situation with no idea what to do. If anyone is so helpful enough to help me with some of the questions or as much as you can then I will be so grateful. I will use this help to learn and understand more about C++ but for now I just need help on these questions.
Thanks.
Q.1
Option A
Using parentheses, rewrite the following expression to indicate the correct order of evaluation. Then evaluate the expression, assuming a=5, b=2, and c=4.a % b * c && c % b * a
Option B
Determine the value of the following expression, assuming a=5, b=2, c=4, and d=5.d % b * c > 5 || c % b * d < 7
Option C
Using parentheses, rewrite the following expression to indicate the correct order of evaluation. Then evaluate the expression, assuming a=5, b=2, and c=4.b % c * a || a % c * b
Q.2
Option A
Write a C++ program to compute and display a person's weekly salary as determined by the following expressions:If the number of hours worked is less than or equal to 40, the person receives $8.00 per hour; otherwise, the person receives $320.00, plus $12.00 for each hour worked over 40 hours.
The program should request the hours worked as input and should display the salary as output.
Option B
Write a C++ program that accepts a character using the cin object and determines whether the character is a lowercase letter. A lowercase letter is any character that is greater than or equal to 'a' and less than or equal to 'z'. If the entered character is a lowercase letter, display the mssage The character just entered is a lowercase letter. If the entered letter is not lowercase, display the message The character just entered is not a lowercase letter.
Q.3This question is in regard to the C++ program
#include <iostream>
#include <iomanip>
using namespace std;int main()
{
double monthlySales, income;cout << "Enter the value of monthly sales: ";
cin >> monthlySales;
if (monthlySales >= 50000.00)
income = 375.00 + .16 * monthlySales;
if (monthlySales >= 40000.00 && monthlySales < 50000.00)
income = 350.00 + .14 * monthlySales;// simplified here from the one in the textbook
if (monthlySales < 40000.00)
income = 200.00 + .03 * monthlySales;cout << "\n\n\The income is $" << income << endl;
return 0;
}and the C++ program
#include <iostream>
#include <iomanip>
using namespace std;int main()
{
double monthlySales, income;cout << "Enter the value of monthly sales: ";
cin >> monthlySales;if (monthlySales >= 50000.00)
income = 375.00 + .16 * monthlySales;
else if (monthlySales >= 40000.00)
income = 350.00 + .14 * monthlySales;// simplified here from the one in the textbook
else
income = 200.00 + .03 * monthlySales;cout << "The income is $" << income << endl;
return 0;
}Option A
Will these two programs produce the same output?
Which program is better? Why?
Draw the flow chart for the first C++ program.Option B
Will these two program produce the same output?
Which program is better? Why?
Draw the flow chart for the second C++ program.
Q.4
Option A, B
For the following C++ program#include <iostream>
using namespace std;int main()
{
int num = 0;
while (num <= 20)
{
num++;
cout << num << " ";
}return 0;
}determine the total number of items displayed, and the first and last numbers printed. Draw the flow chart for the C++ program, and then desk-check the program for the first 5 steps and the last 3.
