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

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
