Write cout statements with stream manipulators that perform the following:
A) Display the number 34.789 in a field of nine spaces with two decimal places of precision.
B) Display the number 7.0 in a field of five spaces with three decimal places of precision.
The decimal point and any trailing zeros should be displayed.

- 2.14 Write an application that displays the numbers 1 to 4 on the same line, with each pair of adjacent numbers separated by one space. Use the following techniques: Use one System.out.println statement. Use four System.out.print statements. Use one System.out.printf statement.arrow_forwardSuppose int1 and int2 are int variables and dec1 and dec2 are double variables. Assume the following input data: 56.50 67 48 62.72What value (if any) is assigned to int1, int2, dec1, and dec2 after each of the following statements executes? (Use the same input for each statement.)a. cin >> dec1 >> int1 >> int2 >> dec2;b. cin >> int1 >> dec1 >> dec2 >> int1;c. cin >> dec1 >> dec2 >> int1 >> int2;d. cin >> int1 >> dec1 >> int2 >> dec2;e. cin >> int1 >> int2 >> dec1 >> dec2;arrow_forwardWhat does the following code segment display? for(f=0; f<3; ++f); write ("{0} ", f); a. 0 b. nothing c. 3 d. 0 1 2arrow_forward
- Explain the steps in finding the output of the following code: #include <iostream>using namespace std; int main() { int arr[5] = {7, 2, 3, 6, 5}; int sum = 0; for (int i = 0; i < 5; ++i) { sum += arr[i]; } cout << " sum : " << sum << endl; return 0;}arrow_forwardMAKE SURE IT DISPLAYS THE LARGEST VALUE AND THAT THE RANGE IS INCLUDED AS WELL AS 5 NUMBERS BEING POSITIVE, 4 NEGATIVE, AND ONE IS ZERO. Write a short computer program in C++ that will read 10 integer numbers entered from a keyboard and then print the smallest number, the largest number, and the average value. Assume all numbers are in the range [-500 … +500]. Execute the program, entering 10 values scattered across the above range, with 5 non-zero positive numbers, 4 negative numbers, and one zero. It is NOT required that that the program check for invalid entries - you may assume that appropriate values are entered correctly. Submit the source program listing and the results. Example: 30 -25 18 -3 10 0 100 -100 200 -200 Smallest = -200 Largest = 200 Average = 3arrow_forwardQ3: Write a program in which user is asked to enter two integers (divisor and dividend) and computes the quotient and remainder. To compute quotient and remainder, both divisor and dividend should be integers.arrow_forward
- 6.10 LAB: Driving costs - functions Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f' % your_value) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. Note: This is a lab from a previous chapter that now requires the use of a function.arrow_forward4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward#include <stdio.h> int main(){float a =3e-1,b=2e-2;printf("a=%f b=%f",a,b);return 0;} note : what is e is here , explain brefily and what is output of the code.arrow_forward
- 3. B) What is the value of num when the following code snippet runs successfully? int num = 100; if (num < 100) { if (num < 50) { num -= 5; } else { num -= 10; } } else { if (num > 150) { num += 5; } else { num += 10; } } C) A store provides 10 percent discount on all items with a price of at least $100. No discount is otherwise applicable. Assume that two variables are declared, discount and price. Write the code segment that does the job.arrow_forward17.3 LAB: Pizza party Given the number of people attending a pizza party, output the number of needed pizzas and total cost. For the calculation, assume that people eat 2 slices on average and each pizza has 12 slices and costs $14.95. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('Cost: ${:.2f}'.format(cost)) Hint: Use the ceil() function from the math module to round up the number of pizzas so that enough pizzas are ordered. Ex: If the input is: 4 the output is: Pizzas: 1 Cost: $14.95 344614.2153518.qx3zqy7arrow_forwardd.
