Why Answe is 4

Question

#include <stdio.h>

int main()
{
int x;
x = sizeof(int);
printf("%d",x);
return (0);
}

Answer 1

It will return the size of int and size of int depend on system

Answer 2

Yes, because size of int differs compiler to compiler. In most of the books and 16 bit systems , the size of int is 2 bytes. And now in modern 32 bit systems , the size of int have become 4 bytes.

Answer 3

Hi remove those irrelevant links please

Answer 4

Thanku Tannu Sharma coffeeunderrun

Answer 5

In 32 bit system int is 4 bytes

Answer 6

Sizeof keyword is present in C to check the datatype storage.It usage in program print the storage in bytes.so here int has storage of 4 bytes

Answer 7

But int datatype is of 2 byte

Answer 8

Tannu Sharma int = 2 bytes, float = 4 bytes , char = 1 byte

Answer 9

Tannu Sharma Means you wants to say int datatype has both 2 bytes and 4 bytes storage

Answer 10

Tannu Sharma Actually it depends on the compiler. Every compiler has it's own rules for such things. Here, the sololearn compiler has size of int data type as 4 bytes.

Answer 11

Range of int data type is 2 or 4 bytes.

Answer 12

because the size of an int is 4 bytes , it’s much better if it was written like that
Printf("%d bytes ",x);

Answer 14

For eg in embedded programming, if you are using 32bit controller then the int is 4bytes or if it is 16bit controller then it is 2bytes.

Okk thanks Satheesh Kumar

Answer 18

But on top of system as some people are saying, it really depends on the compiler. It's upto a compiler's mechanism that has to take int as 2 or 4 bytes, regardless of the system.

Answer 19

****Look at following Programms you will get better Idea.****

#include<stdio.h>
int main()
{
int a;
char ch;
float m;
double n;
long d;
short b;
printf("\nSize of integer is:%d", sizeof (a));
printf("\nSize of character is:%d", sizeof (ch));
printf("\nSize of float value is:%d", sizeof (m));
printf("\nSize of double value is:%d", sizeof (n));
printf("\nSize of long integer is:%d", sizeof (d));
printf("\nSize of short integer is:%d", sizeof (b));
return 0;
}

**OUTPUT**
Size of integer is:4
Size of character is:1
Size of float value is:4
Size of double value is:8
Size of long integer is:8
Size of short integer is:2
