(Display three messages)

Write a program that displays

Welcome to C++

Welcome to Computer Science

Programming is fun
For a hint on this program, please see https://liangcpp.pearsoncmg.com/cpprevel2e.html. If you get a
logic or runtime error, please refer to https://liangcpp.pearsoncmg.com/faq.html.

#include <iostream>

,using namespace std;

int main()
{
cout << "Welcome to C++" << endl;
cout << "Welcome to Computer Science" << endl;
cout << "Programming is fun" << endl;

return 0;
}

(Compute expressions)

Write a program that displays the result of

(9.5 x 4.5 - 2.5 x 3) / (45.5 - 3.5)
For a hint on this program, please see https://liangcpp.pearsoncmg.com/cpprevel2e.html. If you get a
logic or runtime error, please refer https://liangcpp.pearsoncmg.com/faq.html.

#include <iostream>
using namespace std;

int main()
{
cout << (9.5 * 4.5 - 2.5 * 3) / (45.5 - 3.5) << endl;

return 0;
}


Chapter 1: Programming Project 3: (345021-00009)

(Population projection)

The U.S. Census Bureau projects population based on the following assumptions:
One birth every 7 seconds.
One death every 13 seconds.
One new immigrant every 45 seconds

Write a program that displays the population for each of the next five years. Assume the current
population is 312,032,486 and one year has 365 days.

Hint: In C++, if two integers perform division, the result is the quotient. The fractional part is truncated.
For example, is 1 (not 1.25) and is 2 (not 2.5). To get an accuate result with the fractional
part, one of the values involved in the division must be a number with a decimal point. For example, 5.0
/ 4 is 1.25 and .0 is 2.5.

cout << 312032486 + 2 * 365 * 24 * 60 * .0 - 2 * 365 * 24 * 60 * .0 + 2 * 365 * 24 * 60 *
.0 << endl;
cout << 312032486 + 3 * 365 * 24 * 60 * .0 - 3 * 365 * 24 * 60 * .0 + 3 * 365 * 24 * 60 *
.0 << endl;
cout << 312032486 + 4 * 365 * 24 * 60 * .0 - 4 * 365 * 24 * 60 * .0 + 4 * 365 * 24 * 60 *

.0 << endl;

return 0;
}

Chapter 1: Programming Project 4: (345021-00153)

(Simple computation)

The formula for computing the discriminant of a quadratic equation ax^2 + bx + c = 0 is b^2 –
4ac. Write a program that computes the discriminant for the equation 3x^2 + 4x + 5 = 0.

(Physics: acceleration)

Average acceleration is defined as the change of velocity divided by the time taken to make the change,
as shown in the following formula:

a = (v1 - v0) / t

Here, v0 is the starting velocity in meters/second, v1 is the ending velocity in meters/second, and t is
the time span in seconds. Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the
average acceleration.

double dosage;


Programming Quiz 2.3: Question 1: (00000-10968)
Write a statement that reads a floating point (real) value from standard input into temperature.
Assume that temperature has already been declared as a double variable.

cin >> temperature;

Programming Quiz 2.5: Question 1: (00000-10514)
Write a complete program that
 declares an int variable,

 reads a value from the keyboard into that variable, and

 writes to standard output the square of the variable's value.
Besides the number, nothing else should be written to standard output.

#include <iostream>
using namespace std;
int main()
{
int k;
cin >> k;
cout << k * k;

return 0;
}
