Cplusplus Why Does A Character Letter Become The Number 47

Are you wondering why a character letter becomes the number 47 in C++? In this article, we will explore the reasons behind this interesting phenomenon. You will find examples of C++ code that demonstrate why a character letter turns into the number 47, and feel free to modify them as needed.

Understanding the Transformation

In C++, characters are represented by their ASCII values, which are numerical codes assigned to each character. When you assign a character to an integer variable, C++ automatically converts the character to its corresponding ASCII value.

For example, the character ‘A’ has an ASCII value of 65. When you assign ‘A’ to an integer variable, it will be converted to 65.

Similarly, the character ‘1’ has an ASCII value of 49. When you assign ‘1’ to an integer variable, it will be converted to 49.

Now, let’s see why a character letter becomes the number 47 in C++.

Example of C++ Code

Dear [Recipient’s Name],

I am writing this letter to explain why a character letter becomes the number 47 in C++. When you assign the character ‘0’ to an integer variable, it gets converted to its ASCII value, which is 48. However, when you subtract 1 from the ASCII value of ‘0’, you get 47.

This is why in C++, the character ‘0’ becomes the number 47 when assigned to an integer variable.

Sincerely,
[Your Name]
