Find Output Of Program

Question 1 :

What will be the output of the program?

#include < stdio . h >
int main()
{
    char far *near *ptr1;
    char far *far *ptr2;
    char far *huge *ptr3;
    printf("%d, %d, %d\n", sizeof(ptr1), sizeof(ptr2), sizeof(ptr3));
    return 0;
}


A). 4, 4, 8
B). 4, 4, 4
C). 2, 4, 4
D). 2, 4, 8
Answer : Option C

Question 2 :

What will be the output of the program in DOS (Compiler - Turbo C)?

#include < stdio . h >
double i;
int main()
{
    (int)(float)(char) i;
    printf("%d", sizeof((int)(float)(char)i));
    return 0;
}


A). 1
B). 2
C). 4
D). 8
Answer : Option B

Explanation :

Due to the C language is being platform dependent:
In Turbo C (DOS - 16 bit platform), the output will be 2.
But in GCC (Unix/Linux - 32 bit platform), the output will be 4.


Question 3 :

What will be the output of the program?

#include < stdio . h >
int main()
{
    char huge *near *far *ptr1;
    char near *far *huge *ptr2;
    char far *huge *near *ptr3;
    printf("%d, %d, %d\n", sizeof(**ptr1), sizeof(ptr2), sizeof(*ptr3));
    return 0;
}


A). 4, 4, 4
B). 2, 2, 2
C). 2, 8, 4
D). 2, 4, 8
Answer : Option A

Question 4 :

What will be the output of the program (in Turbo C under DOS)?

#include < stdio . h >

int main()
{
    char huge *near *far *ptr1;
    char near *far *huge *ptr2;
    char far *huge *near *ptr3;
    printf("%d, %d, %d\n", sizeof(ptr1), sizeof(ptr2), sizeof(ptr3));
    return 0;
}


A). 4, 4, 8
B). 2, 4, 4
C). 4, 4, 2
D). 2, 4, 8
Answer : Option C

Question 5 :

What will be the output of the program?

#include < stdio . h >
typedef void v;
typedef int i;

int main()
{
    v fun(i, i);
    fun(2, 3);
    return 0;
}
v fun(i a, i b)
{
    i s=2;
    float i;
    printf("%d,", sizeof(i));
    printf(" %d", a*b*s);
}


A). 2, 8
B). 4, 8
C). 2, 4
D). 4, 12
Answer : Option D
