C Pointers Test 4

The correct option is (c).

Explanation:

In the program x points the NULL address. It is invalid to access the NULL address hence the program gives Runtime error.

Therefore the output of the program is Runtime error.

The correct option is (b).

Explanation:

The above null pointer assignment method is incorrect.

The correct way is:

The correct option is (b).

Explanation:

In statement p++ error occur because we cannot perform arithmetic operation on void pointers.

The following error is display on compiling the above program in TurboC.

Compiling PROGRAM.C:

Error PROGRAM.C 8: Size of the type is unknown or zero.

The correct option is (d).

Explanation:

In program 'i' is the variable contain pointer. So it is pointer variable and points toward an integer type in memory location. Therefore 'i' is a pointer to an int.

Now the address of 'j' is assigned to the 'i' pointer, i.e. address of 'j' store to 'i' location.

Therefore the 'i' is a pointer to an int and it stores the address of 'j'.

The correct option is (a).

Explanation:

In program while loop continues until *s is not equal to '\0'. Inside loop character is fetched first and address is incremented later.

Therefore the print statement i.e. printf("%c", *p++); will print the Xyz in output.
