Answer:
</h2>
(i) b = a + 2;
(ii) a = b * 4;
(iii) b = a / 3.14;
(iv) a = b - 8;
<h2>
Explanation:
</h2><h3>Assumptions and comments;
</h3>
=> The code has been written in Java.
=> The variable a, b and c have been declared.
=> The variable c has only been declared but not used since it is not part of the assignment procedures.
<h3>Explanation:
</h3>
The following is the assignment statement that;
<em>(i) Adds 2 to ‘a’ and assigns the result to ‘b’</em>
To add a number to another number or variable, the arithmetic operator (+) is used using the following syntax;
[number] [+] [other number]
In our case, the number is variable a and the other number is 2. Therefore, to add these numbers together we write;
a + 2;
Also, assignment in programming languages is done using the (=) operator. For example to assign a number k to a variable m, we write;
m = k
In our case, the result (a + 2) from above is assigned to variable b as follows;
=> b = a + 2
<em>(ii) Multiplies ‘b’ times 4 and assigns the result to ‘a’.</em>
To multiply a number by another number or variable, the arithmetic operator (*) is used using the following syntax;
[number] [*] [other number]
In our case, the number is variable b and the other number is 4. Therefore, to multiply these numbers we write;
b * 4;
Also,
In our case, the result (b * 4) from above is assigned to variable a as follows;
=> a = b * 4
<em>(iii) Divides ‘a’ by 3.14 and assigns the result to ‘b’.</em>
To divide a number by another number or variable, the arithmetic operator (/) is used using the following syntax;
[number] [/] [other number]
In our case, the number is variable a and the other number is 3.14. Therefore, to divide these numbers we write;
a / 3.14;
Also,
In our case, the result (a / 3.14) from above is assigned to variable b as follows;
=> b = a / 3.14
<em>(iv) Subtracts 8 from ‘b’ and assigns the result to ‘a’.</em>
To subtract a number from another number or variable, the arithmetic operator (-) is used using the following syntax;
[other number] [-] [number]
In our case, the number is 8 and the other variable is b. Therefore, to subtract these numbers we write;
b - 8;
Also,
In our case, the result (b - 8) from above is assigned to variable a as follows;
=> a = b - 8;
