Write about space requirements for variables of different data types?

Answer 1

The space requirements for variables of different data types can vary depending on the programming language and system architecture. Generally, primitive data types like integers and floating-point numbers require a fixed amount of memory based on their size (e.g., 4 bytes for an integer). Larger data types like arrays or structures will require more memory based on the number of elements or fields they contain. It's important to consider memory usage when designing programs to ensure efficient use of resources and avoid memory-related issues like stack overflow or memory leaks.

Answer 2

this is depend upon which processor we are using, 16 bit or 32 bit.

for 16 bit system:

int 2 bytes

short int 2 byte

long int 4 bytes

float 4 bytes

char 1 byte

double 8 bytes

in 32 bit system it takes just double space for int data type.
