You can do the same thing in C, but you should declare it of type char[], not char*, so that you can get its size with the sizeof operator:
char myArray[] = { 0x00, 0x11, 0x22 };
size_t myArraySize = sizeof(myArray); // myArraySize = 3

Is byte a data type in C? - Quora
Answer (1 of 9): No. Or, more precisely, usually, yes. C has the data types char and unsigned char. The C standard says that they must be the size of a character on the platform the program is to run on. Therefore you cannot safely use a char data type as if it was a byte. However, so long as ...

August 10, 2006 - An easy test for this is the following: #include <stdio.h> int main(void) { struct FourBytes { char a,b,c,d; }; switch(sizeof(s truct FourBytes)) { case sizeof(char[4]): puts("Packed nice and tight!"); break; case sizeof(int[4]): puts("Aligned for efficient access."); break; default: puts("Something funky's going on..."); } return 0; } Notwithstanding any of this, your char is going to be promoted to int every time you lay a finger on it. -- Frederick Gotham ...

Just for the sake of completeness, with C99 you can also use compound literals:
char *myArray = (char []) {0x00, 0x11, 0x22 };
If source code compatibility to C++ is a requirement, you better don't use this construct, because it is - afaik - not part of the C++ standard.

C is a statically typed language. The name of the variable along with the type of data it intends to store must be explicitly declared before actually using it.

There is no type byte in C++. You should use typedef before. Something like
typedef std::uint8_t byte;
in C++11, or
typedef unsigned char byte;
in C++03.

The C++ type representing a byte is unsigned char (or other sign flavour of char, but if you want it as plain bytes, unsigned is probably what you're after).
However, in modern C++, you shouldn't be using raw arrays. Use std::vector<unsigned char> if your array is runtime-size, or std::array<unsigned char, N> (C++11) if your array is of static size N. You can pass these to functions via (const) references, like this:
int Analysis(std::vector<unsigned char> &InputImage, int nHeight, int nWidth);
If Analysis does not modify the array or its elements, do this instead:
int Analysis(const std::vector<unsigned char> &InputImage, int nHeight, int nWidth);

3.1. Write a C program that can show the number of bytes used by each of standard data · types, such as int, double, etc (hint: use sizeof ). Use this information to understand the · size of the maximum and minimum signed integers. (hint: INT_MIN, INT_MAX). Look · for same in other data types. Include <limits.h> and <float.h>. See Bb header files links. 3.2. Write a C program to find the storage locations (or addresses) of 3 variables (int, double, string or char*) you declare.

Try
class MissileLauncher
{
public:
MissileLauncher(void);
private:
unsigned char abc[3];
};
or
using byte = unsigned char;
class MissileLauncher
{
public:
MissileLauncher(void);
private:
byte abc[3];
};
**Note: In older compilers (non-C++11) replace the using line with typedef unsigned char byte;

If you want exactly one byte, uint8_t defined in cstdint would be the most expressive.

A char is 1 byte = 8 bits, so there are 2^8 = 256 possible char values.

However this won’t work in C or C++ since 5×7 is 35, meaning using char*s to walk through memory would “skip” a bit every fifth byte (and also because C++ requires bytes to have at least 8 bits). A type that consists of nothing but Plain Old Data. A POD type is a C++ type that has an equivalent in C, and that uses the same rules as C uses for initialization, copying, layout, and addressing. As an example, the C declaration struct Fred x; does not initialize the members of the Fred variable x.
