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;

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.
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.
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
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.
