What is the memory size of integer pointer?
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte
What are the system requirements for language c?
1. byte-organised memory (every bytes of the memory has to be accessible) 2. support for every ASCII characters (0-127)
What is short char in c language?
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
When variable in c gets memory After declaration or initialization?
Definition. Example: extern int x1; /* declaration */ int x2; /* definition */ int x3= 2; /* definition with initialization */
What is the default value of char in java?
Since in c language char take 1 byte in memory because it support limited no of character set. But in the whole universe there are very large no of character like japinise language support 126 character set . Java char support all the character set in the world so it take 2 byte in memory.

How do you write a function which takes 2 arguments - a byte and a field in the byte and returns the value of?
bool F1(int byte,int pos) { return(byte & 1<<pos) } //pos -> position in the field // say byte is b1011 and pos is 2 then it will return value 0
What is byte addressable memory?
a byte is abasic storage unit in memory. when application program instructions and data are transferd to memory from storage devices. byte addressable memory refers to memory address that is accessed one byte (8 bits) at a time as opposed to 2 byte(16 bits), 4 byte(32 bits) or 8 byte(64 bits) addressable memory.
What is aligned address?
A memory address a, is said to be n-byte aligned when a is a multiple of n bytes (where n is a power of 2). In this context a byte is the smallest unit of memory access, i.e. each memory address specifies a different byte.
What is the memory address of the last byte of a 1GB memory?
In a 1GB memory space, the total number of bytes is (1 \times 2^{30} = 1,073,741,824) bytes. Since memory addresses typically start at 0, the memory address of the last byte would be (1,073,741,824 - 1 = 1,073,741,823). Therefore, the memory address of the last byte of a 1GB memory is 1,073,741,823.
What is a byte?
byte">byte1. A group of binary digits or bits (usually eight) operated on as a unit.2. Such a group as a unit of memory size.No, byte is a noun.
What are the system requirements for language c?
1. byte-organised memory (every bytes of the memory has to be accessible) 2. support for every ASCII characters (0-127)
What is the address of the last byte of RAM in the Pep8 memory?
2 bytes or 16 bits
What is the advantage of using sjmp over ljmp?
SJMP is short jump. In this 2-byte instruction the first byte is opcode and second byte is relative address of target location. This can save some byte of memory in many applications where memory space is in short supply where as LJMP (Long Jump) is 3-byte instruction in which 1st byte is opcode and 2nd and 3rd byte represent the 16- bit address of target location.
Is memory in a computer expressed in 5 or 8?
Memory in a computer is typically expressed in powers of 2, such as 2^10 (kilobytes), 2^20 (megabytes), or 2^30 (gigabytes). However, when referring to bytes, it is common to see 8 bits in a byte, which is the fundamental unit of digital data. Thus, while memory sizes are expressed in powers of 2, the smallest unit of memory is based on 8 bits per byte.
What is short char in c language?
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
When variable in c gets memory After declaration or initialization?
