What are some examples of explicit conversion in programming?

What are some examples of explicit conversion in programming?

Explicit conversion, also known as type casting, is when you convert a variable from one type to another intentionally. For example, in Python, you can convert a float to an integer using int(3.14) which results in 3.

Can you give me more examples in different programming languages?

Sure! In Java, you can convert a double to an int like this: int num = (int) 5.99; which will also result in 5. In C++, you can use static_cast<int>(4.7) to achieve the same.

What about converting strings to numbers?

Great question! In JavaScript, you can convert a string to a number using Number('123') or parseInt('123'). In Python, you can use int('123') or float('123.45').

Are there any risks with explicit conversion?

Yes, explicit conversion can lead to data loss or errors if not done carefully. For instance, converting a float to an int will truncate the decimal part, which might not be the desired outcome.
