If you declare variables 'int a = 5, b = 3;' and then perform 'int sum = a + b - 2;', what will be the value of 'sum'?
Understand the Problem
The question is asking to calculate the value of the variable 'sum' after performing the operations with the declared variables 'a' and 'b'. It involves a simple arithmetic operation using the values of 'a' and 'b'.
Answer
The sum is $8$.
Answer for screen readers
The final value of 'sum' is 8.
Steps to Solve
-
Identify the values of the variables We need to know the values of the variables 'a' and 'b'. Let's say, for example, $a = 5$ and $b = 3$.
-
Perform the arithmetic operation The problem states to calculate the value of 'sum' using the variables 'a' and 'b'. We will perform the addition operation: $$ \text{sum} = a + b $$
-
Insert the values and calculate Now, we substitute the values of 'a' and 'b' into the equation. $$ \text{sum} = 5 + 3 $$
-
Calculate the final value Perform the calculation: $$ \text{sum} = 8 $$
The final value of 'sum' is 8.
More Information
The calculation performed is a basic addition operation, which is one of the fundamental arithmetic operations. Arithmetic operations such as addition and subtraction form the basis of more complex mathematical concepts.
Tips
- Forgetting to assign values to 'a' and 'b' before attempting to calculate the 'sum'.
- Not properly performing the addition operation or making a calculation error.
