Answer 1

Answer:#include<stdio.h>

int main(){

   printf("%d\t",sizeof(6.5));

   printf("%d\t",sizeof(90000));

   printf("%d",sizeof('A'));

   return 0;

}

Choose all that apply:

(A) 4 2 1  

(B) 8 2 1  

(C) 4 4 1  

(D) 8 4 1  

(E) 8 4 2

Answer: E

Explanation:

Turbo C++ 3.0: 8 4 2

Turbo C ++4.5: 8 4 2

Linux GCC:  8 4 4

Visual C++: 8 4 4

By default data type of numeric constants is:

6.5 :  double

90000: long int

‘A’: char

In C size of data type varies from compiler to compiler.

In TURBO C 3.0 (16 bit compilers) size of:

double is 8 byte

Long int is 4 byte

Character constant is 2 byte   (size of char data type is one byte)

In TURBO C 4.5 or Linux GCC compilers (32 bit compilers) size of:

double is 8 byte

long int is 8 byte

Character constant is 2 byte
