The sizeof operator yields the size (in bytes) of its operand, which may be an expression or the parenthesized name of a type. The size is determined from the type of the operand. Assuming a clear understanding will lead us to a discussion about bytes.
If you choose someone or something from several people or things that are available, you decide which person or thing you want to have. They will be able to choose their own leaders in democratic elections. There are several patchwork cushions to choose from.
choose When you choose someone or something from a group of people or things, you decide which one you want. Why did he choose these particular places? The past tense of choose is chose, not 'choosed'. The past participle is chosen. I chose a yellow dress.

What is the difference between .size() and .length ? Is .size() only for arraylists and .length only for arrays?
The C++ standard does not specify the size of integral types in bytes, but it specifies a minimum width in bits (see [basic.types.fundamental] p1). You can infer minimum size in bytes from that and the value of the CHAR_BIT macro that defines the number of bits in a byte. In all but the most obscure platforms it's 8, and it can't be less than 8. One additional constraint for char is that its ...
What does the C++ standard say about the size of int, long?
In this case, depending upon what your use case is, you might be better off using int (or long long) for s1 and s2. There are some functions in C/POSIX that could/should use size_t, but don't because of historical reasons. For example, the second parameter to fgets should ideally be size_t, but is int.
I'm curious about this too, since std::size is constexpr in modern C++, it makes the impression to supersede sizeof. When should we still use sizeof instead std::size? What are the pros and cons?
Denoted as Long Size = 64 bits (8byte) Can hold integers of range -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 default value is 0L If your usage of a variable falls in the 32 bit range, use Int, else use long. Usually long is used for scientific computations and stuff like that need much accuracy. (eg. value of pi).
I found two ways to determine how many elements are in a variable… I always get the same values for len () and size (). Is there a difference? Could size () have come with an imported library (like...
To determine the number of elements in the array, we can divide the total size of the array by the size of the array element. You could do this with the type, like this: ... and get the proper answer (68 / 4 = 17), but if the type of a changed you would have a nasty bug if you forgot to change the sizeof(int) as well.
How do I determine the size of my array in C? - Stack Overflow
Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.
Is the size of C "int" 2 bytes or 4 bytes? - Stack Overflow
The OP specifically asked Where do I find the definition of size_t? I landed here searching for the same thing. The cited dup does not discuss where to find the declaration.
Where do I find the definition of size_t, and what is it used for?
