Question

В про­грам­ме «:=» обо­зна­ча­ет опе­ра­тор при­сва­и­ва­ния, знаки «+», «-», «*» и «/» — со­от­вет­ствен­но опе­ра­ции сло­же­ния, вы­чи­та­ния, умно­же­ния и де­ле­ния. Пра­ви­ла вы­пол­не­ния опе­ра­ций и по­ря­док дей­ствий со­от­вет­ству­ют пра­ви­лам ариф­ме­ти­ки. Опре­де­ли­те зна­че­ние пе­ре­мен­ной b после вы­пол­не­ния ал­го­рит­ма: а := 7 b := 4 а := 2*а + 3*b b := a/2*b В от­ве­те ука­жи­те одно целое число — зна­че­ние пе­ре­мен­ной b.

Answer 1

A:= 2*7+3*4 // 26
b:=26/2*4 // 52
Ответ: 52

Answer 2

Solution:

The given algorithm involves a series of assignments and arithmetic operations. Let's break down the steps and calculate the value of the variable b after the algorithm is executed.

1. Step 1: - Assign the value 7 to variable a. - Assign the value 4 to variable b. - Result: a = 7, b = 4.

2. Step 2: - Multiply the current value of a by 2. - Multiply the current value of b by 3. - Result: a = 14, b = 12.

3. Step 3: - Divide the current value of a by 2. - Multiply the current value of b by the result of the previous operation. - Result: a = 7, b = 84.

Therefore, after the algorithm is executed, the value of the variable b is 84.

This calculation is based on the given algorithm and the rules of arithmetic operations.
