Introduction

In this article, we will discuss a simple program in Pascal called FindMax that finds the maximum value in an array of real numbers. The program uses a basic algorithm to iterate through the array and keep track of the maximum value found so far.

The Program Code

program FindMax;

var
a: array[1..10] of Real;
i: Integer;
max: Real;


begin
// Введення елементів масиву
Writeln('Введіть 10 чисел:');
for i := 1 to 10 do
Readln(a[i]);


// Ініціалізація максимального значення
max := a[1];


// Ітерація по масиву для знаходження максимального значення
for i := 2 to 10 do
begin
if a[i] > max then
max := a[i];
end;


// Вивід максимального значення
Writeln('Максимальне значення: ', max);
end.

How the Program Works

The program starts by declaring an array a of 10 real numbers, an integer variable i to use as an index, and a real variable max to store the maximum value found.

The program then prompts the user to input 10 numbers, which are stored in the array a. The maximum value is initialized to the first element of the array, a[1].

The program then iterates through the array starting from the second element (i = 2) to the last element (i = 10). For each element, it checks if the current element is greater than the maximum value found so far. If it is, the maximum value is updated to the current element.

Finally, the program outputs the maximum value found.

Discussion

The program uses a simple algorithm to find the maximum value in an array. The algorithm has a time complexity of O(n), where n is the number of elements in the array. This is because the program iterates through the array once, checking each element against the maximum value found so far.

The program also uses a variable max to store the maximum value found. This variable is initialized to the first element of the array and updated as the program iterates through the array.

Example Use Case

To use the program, simply compile and run it. The program will prompt you to input 10 numbers, which will be stored in the array a. The program will then output the maximum value found.

For example, if you input the following numbers:

1.2
3.4
5.6
7.8
9.0
2.1
4.3
6.5
8.7
10.9

The program will output:

Максимальне значення: 10.9

Q: What is the purpose of the program FindMax?

A: The purpose of the program FindMax is to find the maximum value in an array of real numbers.

Q: How does the program FindMax work?

A: The program FindMax works by iterating through the array and keeping track of the maximum value found so far. It starts by initializing the maximum value to the first element of the array, and then iterates through the rest of the array, updating the maximum value if a larger value is found.

Q: What is the time complexity of the program FindMax?

A: The time complexity of the program FindMax is O(n), where n is the number of elements in the array. This is because the program iterates through the array once, checking each element against the maximum value found so far.
