Question

Определить сколько раз исполнится тело цикла и чему будет равно значение переменной S: S:=0 ; k:=2 for i:=1 to 3 do begin S:=S+k: k:= k+1

Answer 1

S:= 0+2=2
K= 2+1=3
S=2+3=5
K=3+1=4
S=5+4=9
K=4+1=5

Answer 2

Значение переменной S , после выполнения цикла, будет равно : S = 9;

Answer 3

Calculating the Value of a Variable S in a Given Code

To determine the value of the variable S and the number of times the body of the loop will be executed, let's analyze the provided code:

S := 0;
k := 2;
for i := 1 to 3 do
begin
  S := S + k;
  k := k + 1;
end;

Number of Times the Body of the Loop Will Execute

The loop is set to iterate from 1 to 3, inclusive, which means the body of the loop will execute three times.

Calculating the Value of Variable S

The value of S can be calculated by tracing the loop execution:

1. Iteration 1: - S = 0 + 2 = 2 - k = 2 + 1 = 3

2. Iteration 2: - S = 2 + 3 = 5 - k = 3 + 1 = 4

3. Iteration 3: - S = 5 + 4 = 9 - k = 4 + 1 = 5

So, after the loop executes, the value of S will be 9.

Therefore, the body of the loop will execute 3 times, and the value of the variable S will be 9.
