However, incorrect logic in the conditions can lead to wrong results in certain cases.- **Condition Analysis:** - The first `if` condition checks if `a > b` and `b > c`. If true, it sets `low` to `c`. - The second `if` condition checks if `a > b` and `c > b`. If true, it sets `low` to `b`. If false, it defaults `low` to `a`.Thus, the code fails in cases where `a` is the smallest number, as the logic erroneously defaults `low` to `a`. This means the code segment will not work correctly when both `b` and `c` are greater than `a`, like in option **C**. ### Correct Answer:- **C**: \( a = 1, \ b = 2

Operations

In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.

Basic Operators

An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.

Division Operator

We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:

Modulus Operator

Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.

Operators

In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

Question

This is test review, e is the correct answer. I do not know why the else statement overrides the else statement

# Unit 3 Progress Check: MCQ

### Instructions

Assume that the `int` variables `a`, `b`, `c`, and `low` have been properly declared and initialized. The code segment below is intended to print the sum of the greatest two of the three values but does not work in some cases.

```java
if (a > b && b > c) {
low = c;
}
if (a > b && c > b) {
low = b;
} else {
low = a;
}
System.out.println(a + b + c - low);
```

For which of the following values of `a`, `b`, and `c` does the code segment NOT print the correct value?

- **A**: \( a = 1, \ b = 1, \ c = 2 \)
- **B**: \( a = 1, \ b = 2, \ c = 1 \)
- **C**: \( a = 1, \ b = 2, \ c = 3 \)
- **D**: \( a = 2, \ b = 2, \ c = 2 \)
- **E**: \( a = 3, \ b = 2, \ c = 1 \) (Correct)

### Analysis

The problem tests understanding of control flow and conditional statements in Java. The code is supposed to find the smallest of three numbers and subtract it from their sum to get the sum of the two largest numbers. However, incorrect logic in the conditions can lead to wrong results in certain cases.

- **Condition Analysis:**
- The first `if` condition checks if `a > b` and `b > c`. If true, it sets `low` to `c`.
- The second `if` condition checks if `a > b` and `c > b`. If true, it sets `low` to `b`. If false, it defaults `low` to `a`.

Thus, the code fails in cases where `a` is the smallest number, as the logic erroneously defaults `low` to `a`. This means the code segment will not work correctly when both `b` and `c` are greater than `a`, like in option **C**.

### Correct Answer:
- **C**: \( a = 1, \ b = 2
