Question

Must be written in C++!

 1. Given an array of integers with 10 values, provide the necessary C++ code to sort the array in descending order (must use bubble sort or selection sort) and output them to an output file with at most 4 values per line. The output will go to the file problem1.txt. Do output your name to the output file.   

Use the following array to test:

int arr[10] = {5, 3, 6, 7, 1, 9, 0, 8, 1, 4};

 

Sample output file (problem2.txt):

Generated by [Your name]

 

9   8   7    6

5   4   3    1

1   0

 

Test your code on two additional arrays, one of size 15 and another of size 25.  Please submit your tests along with your source code.

 
 
 

  2.  Write a program that inputs a list of real values from a data file, problem2.txt, and print the count, largest value, and smallest value to the screen. Submit both source code and output when using problem2.txt.

 

Here is one sample input file, problem2.txt (there is an extra blank line at the end and you need to create this file):

1.5

2.1

0.2

1.7

0.5

 

Sample output:
Author: [Your name]

 

Count:    5

Largest:  2.1

Smallest: 0.2

 


Here is another sample input file if you would like to try (there is an extra blank line at the end):

2.5

2.1

1.2

 

Sample output:

Author: [Your name]

 

Count:    3

Largest:  2.5

Smallest: 1.2

 
 
 

 3.  Complete the two modules in C++ (void functions) to display the two specified patterns when calling them from main. Set up main and the two void functions. Run the program with the four calls below and confirm the output.  Submit both source code and output.

 

      // calls from main

      rectanglePattern(3, 4);    // 3 by 4 rectangle of # characters

      rectanglePattern(2, 5);    // 2 by 5 rectangle of # characters

      trianglePattern(3, ‘*’);

      trianglePattern(4, ‘#’);

 

 

            Sample output:

Author: [Your name]

 

      ####

      ####

      ####

 

      #####

      #####

 

      *

      **

      ***

 

      #

      ##

      ###

      ####

 

You must use a nested loop and output one ‘#’ at a time inside the inner loop.  Each line has up to rows ‘#’ characters (inner loop) and there are rows of lines of characters (outer loop). 

 

         void rectanglePattern(int rows, int cols)

            // set up a nested loop using rows and cols

            // use cout << ‘#’; inside the nested loop

 

 

 

You must use a nested loop and output one character at a time inside the inner loop.  The first line has one character and the nth row has n characters.

 

         void trianglePattern(int rows, char c)

            // set up a nested loop using row and outer loop counter

            // use cout << c; inside the nested loop
