What will be the output of the following code?#include <iostream>...
Understanding the Code
The provided C++ code snippet performs a simple arithmetic operation using the modulus operator. Let’s break it down to understand its output.
Code Breakdown
- The code includes the standard input-output stream library with `#include`.
- It uses the `std` namespace to avoid prefixing standard library functions with `std::`.
- In the `main()` function:
- Two integers, `x` and `y`, are initialized with values 10 and 3, respectively.
- The modulus operator `%` is applied to `x` and `y`.
Modulus Operator Explained
- The modulus operator `%` returns the remainder of the division of two numbers.
- In this case, `x % y` calculates the remainder of dividing `10` by `3`.
Calculation Steps
1. Division: When you divide `10` by `3`, the quotient is `3` (since 3 goes into 10 three times).
2. Remainder: The multiplication of the quotient by the divisor gives `3 * 3 = 9`.
3. Final Step: Subtract this product from 10:
- `10 - 9 = 1`.
Thus, the remainder when dividing `10` by `3` is `1`.
Output Explanation
- The program then outputs this remainder using `cout < x="" %="" y="" />< />
- Therefore, the output of the code will be `1`.
Conclusion
The correct answer is option 'A', as the result of `10 % 3` is indeed `1`.
