What will be the output of the given Pascal and Python code snippets?
Ответ:
Let's analyze the Pascal code:
n := 0;s := 0;while s <= 35 do begin n := n + 1; s := s + 4end;write(n);The code initializes
n and s to 0. The while loop continues as long as s is less than or equal to 35. Inside the loop, n is incremented by 1, and s is incremented by 4. Let's trace the values:- Initially,
n = 0 and s = 0.- Loop 1:
n = 1, s = 4- Loop 2:
n = 2, s = 8- Loop 3:
n = 3, s = 12- Loop 4:
n = 4, s = 16- Loop 5:
n = 5, s = 20- Loop 6:
n = 6, s = 24- Loop 7:
n = 7, s = 28- Loop 8:
n = 8, s = 32- Loop 9:
n = 9, s = 36The loop terminates when
s becomes 36, which is greater than 35. The final value of n is 9. Therefore, the code will print 9.Now let's analyze the Python code:
n = 0s = 0while s <= 35: n += 1 s += 4print(n)This code does the exact same thing as the Pascal code. It initializes
n and s to 0. The while loop continues as long as s is less than or equal to 35. Inside the loop, n is incremented by 1, and s is incremented by 4. Let's trace the values.- Initially,
n = 0 and s = 0.- Loop 1:
n = 1, s = 4- Loop 2:
n = 2, s = 8- Loop 3:
n = 3, s = 12- Loop 4:
n = 4, s = 16- Loop 5:
n = 5, s = 20- Loop 6:
n = 6, s = 24- Loop 7:
n = 7, s = 28- Loop 8:
n = 8, s = 32- Loop 9:
n = 9, s = 36The loop terminates when
s becomes 36, which is greater than 35. The final value of n is 9. Therefore, the code will print 9.Answer: 9
