Size of a Char is MCQ: A Simple Guide to C and C++ Char Sizes
When talking about the “size of a char is mcq”, you'll want to dive into the nuances of C and C++ programming languages. In C and C++, the size of a char is typically 1 byte, which is equivalent to 8 bits. This has been the standard since C was first released in 1978 and C++ in 1989. But here's a twist: the size can vary depending on the compiler and architecture! Let's break it down in simpler terms.
What is a Char?
Before we dive in, it’s crucial to understand what a char is. In simple words, a char is a data type that stores a single character, such as 'a', 'Z', or '5'. This means that when you create a variable of type char, you can use it to store letters or symbols.

The Usual Size of a Char
Typically, in C and C++, the size of a char is 1 byte. This has been a standard since 1978 for C and since 1989 for C++. However, in 2003, the C99 standard allowed it to vary between 1, 2, or 4 bytes, depending on the computer's architecture. Similarly, in 2011, the C++11 standard followed suit.

When Size of a Char Varies
Now, let's talk about the scenarios where the size of a char might differ. Specifically, on a 64-bit machine, the size of a char may be 2 bytes. This is important to remember because it can affect how your code behaves.

Size of a Char in Arrays
When you're dealing with char arrays, which are basically strings, there’s an extra twist. A char array is usually two bytes longer than the size of a char. For instance, if the size of a char is 1 byte, the char array will have an extra two bytes.

Year | Event |
---|---|
1978 | C programming language released, char is 1 byte |
1989 | C++ programming language released, char is 1 byte |
2003 | C99 standard allows char to be 1, 2, or 4 bytes |
2011 | C++11 standard follows C99 |
In Summary
So, the size of a char in C and C++ is usually 1 byte. But watch out, because depending on your machine and compiler, this
can change! It's always wise to check the documentation of the compiler you are using.
FAQs
Q: What is the standard size of a char in C and C++?
