Method Overloading: Temperature Conversion

Learning Objective: Implement different processing by parameter type using overloading

Define convertToFahrenheit method with same name but different parameter types (int, double, String) to convert Celsius to Fahrenheit. Implement calculation processing for each type.

Input

None (use fixed values)

Output

[celsius]C = [fahrenheit]F
```java

Conversion formula: Fahrenheit = Celsius × 9/5 + 32

## Examples

### Example 1: Basic values
Output:
```java
0C = 32F
25.5C = 77.9F
30C = 86.0F
```java

### Example 2: Different values
Output:
```java
100C = 212F
37.5C = 99.5F
15C = 59.0F
