Question

В первый час работы, рабочий изготавливает a деталей, за последующий час на d деталей больше, чем за предыдущий. Разработайте программу, которая подсчитает, сколько деталей изготовил рабочий за k часов работы.

Answer 1

Var a,d,k,i,ak,s:integer;
begin
writeln('a, d, k:');
readln(a,d,k);
s:=0; ak:=a-d;
for i:=1 to k do
 begin
 ak:=ak+d;
 s:=s+ak;
 end;
writeln('s = ',s);
end.

Пример:
a, d, k:
10 2 5
s = 70

Answer 2

Problem Analysis

We are given that in the first hour of work, a worker produces 'a' number of parts, and in each subsequent hour, the worker produces 'd' more parts than in the previous hour. We need to develop a program that calculates the total number of parts produced by the worker in 'k' hours of work.

Plan

To solve this problem, we can use a loop to iterate through each hour of work and keep track of the total number of parts produced. We will start with the initial number of parts produced in the first hour and increment it by 'd' in each subsequent hour. Finally, we will return the total number of parts produced after 'k' hours of work.

Pseudocode

Here's a pseudocode representation of the program:

function calculateTotalParts(a, d, k):
    totalParts = a
    for hour in range(2, k+1):
        totalParts = totalParts + d
    return totalParts

Python Implementation

Here's the Python implementation of the program:

def calculateTotalParts(a, d, k):
    totalParts = a
    for hour in range(2, k+1):
        totalParts = totalParts + d
    return totalParts

# Example usage
a = 10  # Number of parts produced in the first hour
d = 5   # Number of additional parts produced in each subsequent hour
k = 4   # Number of hours of work
totalParts = calculateTotalParts(a, d, k)
print("Total number of parts produced:", totalParts)

Example Output

For the given example values of `a = 10`, `d = 5`, and `k = 4`, the program will output: ``` Total number of parts produced: 25 ```

Explanation

In the first hour, the worker produces 10 parts. In the second hour, the worker produces 10 + 5 = 15 parts. In the third hour, the worker produces 15 + 5 = 20 parts. In the fourth hour, the worker produces 20 + 5 = 25 parts. Therefore, the total number of parts produced after 4 hours of work is 25.
