// Your Name // CS 52 // Assignment #3

2. Properly indent, format and comment your code as necessary
3. Problem 1                               Matrix

Create a 5×5 matrix of int values as shown below. Write a program that finds the minimum, maximum, and average value of all values in the matrix. Create a function for each value that is computed (max, min, avg).  Print out the results (limit the average to two decimal points!).

Matrix: [ 7, 2, 10, 3, 6],

[ 1, 12, 2, 0, 20],

[ 3,14,19, 5, 4],

[ 6, 0, 17, 18, 8],

[ 1, 13, 10, 9, 11];

Example: Min: 0, Max: 20, Avg: 8.04

Problem 2                               Dynamically Allocated Arrays

Write a program that dynamically allocates an array based on a size determined by the user. You must declare the array as a pointer to get full credit! The program then uses a pointer to initialize each element in the array with a value that is also entered by a user. Finally, sort the array and print it to the console.

 

Example: Enter a size: 5 Item 1: 3 Item 2: 8 Item 3: 5 Item 4: 2 Item 5: 9 Sorted: 2, 3, 5, 8, 9	Example 2:
		Enter a size: 3 Item 1: 15 Item 2: 3 Item 3: 7 Sorted: 3, 7, 15
		1

Problem 3                               First Non-repeated char

 Write a program that prompts the user for a string (the string may consist of multiple words). Implement a function that finds and returns the first non-repeated char in the string. The program calls the function and prints out the returned char.

 Problem 4                               Count Chars In File

 Write a program that counts the number of upper case letters, lower case letters, digits, spaces, and any other chars in a file. The program prompts the user to enter a file name (including file path). The program then opens the file and counts each of the before mentioned categories, then prints the output.

Hint:

• Use the        library  #include<fstream>
• Create a variable             of          type      ifstream              with      the        file        name   passed in           as              argument,        g.       ifstream myFile(filename);
• Use getline(cin, string);  function            to              read     an         entire   line       including              whitespace

 

Example:

Enter a file: /Users/kalisch/Desktop/sample.txt

File contains

Lowercase letters: 1938

Uppercase letters: 128

Digits: 17

Spaces: 35
