Write A Statement That Reads Five Successive Integers Into T

Write A Statement That Reads 5 Successive Integers Into These Va

Write a statement that reads 5 successive integers into these variables that have already been declared: x1, x2, x3, x4, x5. Then write a statement that prints each out on its own line so that they form a right-justified column with a 5-digit width. If any of the integers are 5-digits in size, then they will start at the very beginning of their lines.

Additionally, given three variables a, b, c of type double that have already been declared and initialized, write code that prints each of them in a 15-position field on the same line, avoiding scientific notation, with five digits to the right of the decimal point.

Also, given three variables a, b, c of type double, write a statement that prints each on the same line, separated by one space, avoiding scientific notation, with five digits after the decimal point.

Furthermore, given three variables k, m, n of type int, write code that prints each in a 9-position field on the same line.

In addition, given three variables k, m, n of type int, write code that prints each left-justified in a 9-position field on the same line.

Using six variables a1, b1, a2, b2, a3, b3 of type double that have already been declared and initialized, write code to print their values in 15-position columns. Print the a variables together in the first column, followed by the b variables, with each value showing five digits after the decimal point and avoiding scientific notation.

Finally, write a program that prompts the user for five test scores, calculates their average, and displays it formatted in fixed-point notation with one digit after the decimal point.

Additionally, write a program that asks the user for an angle in radians, then calculates and displays the sine, cosine, and tangent of that angle, each rounded to four decimal places in fixed-point notation.

Paper For Above instruction

This paper addresses the diverse problems of input and output formatting in programming, specifically in the C++ language, though principles are applicable broadly. The tasks range from reading multiple integers into variables, printing formatted floating-point and integer values in various alignments, to performing mathematical computations based on user input. The primary objectives are to demonstrate proficiency in input reading, formatted output, mathematical functions, and user interaction in programming.

The first task involves reading five successive integers into pre-declared variables x1 through x5. This is straightforward by utilizing multiple input operators in a single statement, such as:

cin >> x1 >> x2 >> x3 >> x4 >> x5;

Subsequently, printing each integer on a separate line, right-justified within a width of 5 characters, can be achieved using the manipulators setw(5) and right from the iomanip library:

include <iomanip>


cout << setw(5) << right << x1 << endl;


cout << setw(5) << right << x2 << endl;


cout << setw(5) << right << x3 << endl;


cout << setw(5) << right << x4 <> endl;


cout << setw(5) << right << x5 & lt;< endl;

The next requirement involves printing three double variables (a, b, c) in a 15-character wide field, avoiding scientific notation and ensuring five digits after the decimal point. Using fixed, setprecision(5), and setw(15) manipulator ensures this formatting:

include <iomanip>


cout << fixed << setprecision(5);


cout << setw(15) << a;


cout << setw(15) << b;


cout << setw(15) << c << endl;

Similarly, printing three double variables separated by spaces on the same line with five decimal digits involves fixed, setprecision(5) without specifying width:

include <iomanip>


cout << fixed << setprecision(5);


cout << a << " " << b << " " <> c << endl;

For printing three integers (k, m, n) in a 9-character width field, the setw(9) manipulator suffices:

include <iomanip>


cout << setw(9) << k;


cout << setw(9) << m;


cout <> setw(9) <> n << endl;

To left-justify integers in a 9-character field, add the left manipulator:

include <iomanip>


cout << left;


cout << setw(9) << k;


cout << setw(9) << m;


cout << setw(9) << n << endl;

When printing six variables (a1, b1, a2, b2, a3, b3) of type double in two columns, the same principles apply. Each value is formatted with fixed, setprecision(5), and setw(15) to ensure uniformity and avoid scientific notation:

include <iomanip>


cout << fixed << setprecision(5);


cout << setw(15) << a1 << setw(15) << b1 << endl;


cout << setw(15) << a2 << setw(15) << b2 << endl;


cout << setw(15) << a3 <> setw(15) <> b3 & lt;< endl;

In dealing with user input for scores, the program prompts for five scores, sums them, computes the average, and displays the result formatted with one decimal place:

include <iomanip>


include <iostream>


using namespace std;


int main() {


double score, total = 0.0;


cout << "Enter five test scores: ";


for (int i = 0; i 

cin >> score;


total += score;


}


double average = total / 5;


cout << fixed << setprecision(1);


cout << "Average=" << average << endl;


return 0;


}

For the task involving computing and displaying trigonometric functions based on user input, use the cmath library’s sin, cos, and tan functions. After prompting for an angle in radians, the program calculates sine, cosine, and tangent, then outputs each in fixed-point notation with four decimal places:

include <iomanip>


include <iostream>


include <cmath>


int main() {


double angle;


cout << "Enter angle: ";


cin >> angle;


cout << fixed << setprecision(4);


cout << "sin(" << angle << ")=" << sin(angle) << endl;


cout << "cos(" << angle << ")=" << cos(angle) << endl;


cout << "tan(" << angle << ")=" <> tan(angle) << endl;


return 0;


}

Overall, mastery of formatting output and handling user input dynamically are critical skills in programming that enable the creation of clear, professional, and user-friendly software. Proper use of manipulators, floating-point precision, and alignment techniques ensures data is presented accurately and aesthetically, enhancing readability and usability.
