Program:

#include<stdio.h>
#include<conio.h>
void main( ) 
{
          int i,j;
          j = 10;
          i = j++ - j++;
          printf("%d %d", i,j);

 }

 Solution:

       j=10
       i= 10 - 10
j value  is incremented by two times.
So,Output is 0, 12

What would be the output of the following following Program?

by  0

#include<stdio.h>
#include<conio.h>
void main( )
{
               int a[ ] = {1,2,3,4,5};
               printf("%u,%u,%u",&a,a,&a[0]);
}

Options:

A)65516,65518,65560
B)65516,65516,1
C)65516,1,1
D)65516,65516,65516


Answer Option D)
-->for example the base address of the array a is 65516.
-->a, &a are points to the base address of the array and &a[0] is points to the address of first element in the array i.e base address.
So, answer is 65516,65516,65516.

}

Options:
A)%x,10,10,%x
B)10,10,10,11
C)%x,10,%i,%x
D)a,10,10,b

Answer Option D)
-->%d and %i are used for integer datatype.
-->%x is used for hexadecimal notaion.
Number ---> HexaDecimal Value
   1        --->          1
   2        --->          2
   3        --->          3
   4        --->          4
   5        --->          5
   6        --->          6
   7        --->          7
   8        --->          8
   9        --->          9
   10      --->          a
   11      --->          b
   12      --->          c
   13      --->          d

           {
                    printf("You are Good");
           }
           else
           {
                    printf("You are Perfect");
           }
}

Options:
A)You are Perfect
B)You are Good
C)an error
D)none

Answer Option B)
Because i=5 is true statement
The purpose of the if statement is , if the condition is true then if block executed. Otherwise else block executed.

by  0


#include<stdio.h>
#include<conio.h>
void main( )
{
            char far *p1, *p2;
            printf("%d,%d",sizeof(p1),sizeof(p2));
}

Options:
A)4,2
B)2,2
C)4,4
D) an error




Answer Option A)

-->A Pointer size is 2 bytes (for 16-bit compiler)
-->The size of far pointer is 4 bytes
-->The size of the huge pointer is 4 bytes
-->the far pointer is 16-bit segment value
-->the huge pointr is 16-bit offset value
