The 1st solution uses strlen and based on cplusplus.com, The length of a C string is determined by the terminating null-character: A C string is as long as the number of characters between the beginning of the string and the terminating null character (without including the terminating null character itself).

How large is a string in C?
A string in C is simply an array of characters. The following line declares an array that can hold a string of up to 99 characters. char str[100]; It holds characters as you would expect: str[0] is the first character of the string, str[1] is the second character, and so on.
How large is a string in C in bytes?
The maximum length of a string literal allowed in Microsoft C is approximately 2,048 bytes.
How big is a string?
The strings of string theory are unimaginably small. Your average string, if it exists, is about 10–33 centimeters long. That’s a millionth of a billionth of a billionth of a billionth of a centimeter. If an atom were magnified to the size of the solar system, a string would be the size of a tree.
How much space is a string?
An empty String takes 40 bytes—enough memory to fit 20 Java characters.
What is the max size of a string?
String limitations
| Value | Maximum Limit |
|---|---|
| Length of character constant | 32,672 |
| Length of concatenated character string | 2,147,483,647 |
| Length of concatenated binary string | 2,147,483,647 |
| Number of hex constant digits | 16,336 |
What is size of char in C?
1 byte
Char Size. The size of both unsigned and signed char is 1 byte always, irrespective of what compiler we use.
Why is size 32 string?
So this string implementation is 32 because that’s the way it was built in this implementation and it will by 16 in other implementations and 64 in yet another. The size of the string will (like water) depend on the environment it is used in.
How much data is a string?
It depends on the encoding, ebcdic take 4 bits for character. UTF-8 take 8 bits per character (one byte). Some encodings use both 8 bits and 16 bits for representing characters…
How many bytes is a string of data?
How many bytes for anything?
| Information object | How many bytes? |
|---|---|
| A binary decision | 1 bit |
| A single text character | 1 or 2 bytes |
| A typical text word | 10 to 20 bytes |
| A line of text | 70 bytes |
How long is a length of string?
Phrase. How long is a piece of string? (colloquial, often humorous, rhetorical question) Used as a response to a question such as “How long will it take?” or “How big is it?” when the length or size is unknown, infinite, variable, or relative.
How long is a string in C++?
When we discuss the length of a string, we’re usually referring to the number of that string’s characters. In C++, string length really represents the number of bytes used to encode the given string. Since one byte in C++ usually maps to one character, this metric mostly means “number of characters,” too.
How many bytes is a char?
1 byte
Windows 64-bit applications
| Name | Length |
|---|---|
| char | 1 byte |
| short | 2 bytes |
| int | 4 bytes |
| long | 4 bytes |
How many bytes is Hello World?
125 bytes
“Hello world” in only 125 bytes in Flash! But, making every byte count, we can go one step further. Embedded Studio comes with two sets of system libraries, one optimized for size, and the other one optimized for speed.
How many bytes are required to display the string?
Set intrinsic data types
| Data type | Storage size |
|---|---|
| String (variable-length) | 10 bytes + string length |
| String (fixed-length) | Length of string |
| Variant (with numbers) | 16 bytes |
| Variant (with characters) | 22 bytes + string length (24 bytes on 64-bit systems) |
What is a string in C language?
In C programming, a string is a sequence of characters terminated with a null character . For example: char c[] = “c string”; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character at the end by default.
How much data can a string store?
MAX_VALUE, which is 2^31 – 1 (or approximately 2 billion.) So you can have a String of 2,147,483,647 characters, theoretically.
What is the maximum length?
Maximum Length means the largest total length of a species or species group that may be legally possessed, measured from the tip of the snout to the end of the tail.
Is char * a string?
char* is a pointer to a character. char is a character. A string is not a character. A string is a sequence of characters.

The size of int is usually 4 bytes (32 bits). And, it can take 232 distinct states from -2147483648 to 2147483647 .
What is sizeof () in C?
The sizeof() function in C is a built-in function that is used to calculate the size (in bytes)that a data type occupies in ​the computer’s memory. A computer’s memory is a collection of byte-addressable chunks.
