In C, long int data type occupies 4 bytes (32 bits) of memory to store an integer value.long int (or) signed long int data type denotes a 32-bit signed integer that can hold any value between -2,147,483,648 (-231) and 2,147,483,647 (231-1).unsigned long int data type denotes a 32-bit integer.It does not use a bit to store the sign. Hence, it can hold only positive values between 0 and 4,294,967,295 (232-1).long is used whenever an int data type is not sufficient to represent a number.Consider the following example that uses long int data type:#include <stdio.h>void main() { long int num1 = 12345676L; long int num2 = 23L; long int total; total = num1 + num2; printf("Total of the given two numbers = %ld\n", total);}Here, 4 bytes of memory is allocated to each variable num1, num2 and they are initialized with long literals 12345676L and 23L respectively.As you can notice, the long literal values are suffixed with char 'L' (lowercase of 'L' can also be used, however the uppercase is more readable)If any variable is not initialized, then the local variable contains garbage value (i.e., some preexisting value in the allocated memory which may not make sense) by default. Some compilers like gcc automatically initialize the uninitialized int variables to zero.Click on Live Demo to learn about long int data type in C.Select all the correct statements from the given statements.The max value of a long is twice the max value of an intA long can also represent decimal (fractional) numbers.A long literal value can be enclosed within single or double quotes.A long literal value can be a negative or a positive number within the range of -231 and 231-1.

In C, short int data type occupies 2 bytes (16 bits) of memory to store an integer value.short int (or) signed short int data type denotes a 16-bit signed integer, which can hold any value between - 32,768 (-215) and 32,767 (215-1).unsigned short int data type denotes a 16-bit integer and does not use a bit to store the sign. Hence, it can hold only positive values between 0 and 65535 (216-1).The OS architecture (i.e either 16-bit, 32-bit or 64-bit) plays an important role in determining the memory occupied by the short int data type.In a 16-bit OS, 2 bytes (16 bits) of memory is allocated to a short int. However, only 1 byte is used to store the value, while the other remains empty.Unlike a normal int data type, 2 bytes (16 bits) of memory is allocated in a system with 32-bit OS and 4 bytes (32 bits) of memory in a system with 64-bit OS to the short int data type .Consider the following example using short int data type:#include <stdio.h>void main() { short int num1 = 6; short int num2 = 9; short int result; result = num1 * num2; printf("Product of the given two numbers = %d\n", result);}Here, 2 bytes of memory is allocated to each variable num1, num2 and they are initialized with integer constants 6 and 9 respectively.If a variable is not initialized, then by default, the local variable contains garbage value ( i.e., some preexisting value in the allocated memory which may not make any sense). Some compilers like gcc automatically initialize the uninitialized int variables to zero.Click on Live Demo to know more about short int data type in C.Select all the correct statements from the given statements.We can use a short data type to store a string.A short literal value can be enclosed in single or double quotes.short int allocates lesser memory than the int data type.A short int literal value can be a negative or a positive number within the range of -215 and 215-1.

MEMORY SIZE OF THE INT DATA TYPE:

Is the number of bytes of long int and float data types the same??
