Use data-type 'long long' or 'int64_t' (from inttypes.h)
Because you are using a compiler (TurboC, most likely) which was developed some 25 years ago, for a 16-bit platform.
If all four bytes are being used for its value (i.e. this is an unsigned integer) then you have 8 * 4 = 32 bits, so your range is from 0 to 2^32 (4,294,967,296) Remember, the size of various data types in C and C++ is architecture dependent. See limits.h (/usr/include/limits.h in Linux)
There is no such thing as "short char" You either mean char or short int. a char is a variable declaration that holds one character, usually 8 bits long (1 byte) short int (or simply short) is a 16 bit (2 byte) integer
In JavaA char in Java is a 16-bit integer, which maps to a subset of Unicode.In C A char in C is an 8-bit integer, which maps to standard ASCII.Note that in both Java and in C you can use a char value like a normal integer type: char c = 48;
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte
It depends on the context. Each database and computer language define an "integer". In the C language an integer is defined by the hardware. It can vary from 2 to 8 bytes or more.

There is not built-in 'byte' type in C, but you can define it: typedef unsigned char byte; byte bmin=0, bmax=255;
#include <inttypes.h> int32_t myint; char str [] = "Test"; myint = *(int32_t *)str;

There is no such thing as a negative ASCII value. ASCII values are always in the range 0-255. In C++, a char is defined as an unsigned integer of 8-bits in length (wide chars are unsigned integers of 16-bit length). Since they are unsigned, they can never be negative. C differs from C++ in that a C char is generally represented as a signed integer (typically 32-bits on a 32-bit system). However, when cast as a character, only the low-order byte is used, which effectively ignores the sign in the high-order byte. In other words, the absolute value is used, regardless of the sign. The same applies to wide characters.
a character/byte as defined in the C programming language is one byte (8 bits). A string can be as short as one byte and can be as long as the physical memory limits can contain it.
strlen is the C library function that accepts a pointer to a char array and returns an integer specifying the number of characters (in bytes) of the array. This function is usually not used any more, because it does not support multi-byte characters, such as UTF-8.
it depend on the language which are you using if it is c than 1 bytes if it is java than 2 bytes and vary for the languages but it is generally either 1 or 2 1 byte =8 bit
