Question 1
‘ptrdata’ is a pointer to a data type. The expression *ptrdata++ is evaluated as (in C++) :
Depends on compiler
(*ptrdata)++
*(ptrdata)++
*(ptrdata++)
Question 2
What is printed by the following C program?
18
19
21
22
Question 3
What will be output of the following program? Assume that you are running this program in little-endian processor.
1
320
64
Compilation error
Question 4
Consider the following C function
The output of the program is
SI
IT
TI
17
Question 5
Question 6
In the context of the below program snippet, pick the best answer.
Which of the given printf statement(s) would be able to print arr[5][5][5]
only (i) would compile and print 123.
both (i) and (ii) would compile and both would print 123.
only (i), (ii) and (iii) would compile but only (i) and (ii) would print 123.
only (i), (ii) and (iii) would compile and all three would print 123.
all (i), (ii), (iii) and (iv) would compile but only (i) and (ii) would print 123.
all (i), (ii), (iii) and (iv) would compile and all would print 123.
Question 7
Pick the best statement for the above C program snippet.
Assigning (void *)0 to pVoid isn’t correct because memory hasn’t been allocated. That’s why no compile error but it'll result in run time error.
Assigning (void *)0 to pVoid isn’t correct because a hard coded value (here zero i.e. 0) can’t assigned to any pointer. That’s why it'll result in compile error.
No compile issue and no run time issue. And the size of the void pointer i.e. pVoid would equal to size of int.
sizeof() operator isn’t defined for a pointer of void type.
Question 8
Choose the correct statement w.r.t. above C program.
malloc() for ppInt1 and ppInt2 isn’t correct. It’ll give compile time error.
free(*ppInt2) is not correct. It’ll give compile time error.
free(*ppInt2) is not correct. It’ll give run time error.
No issue with any of the malloc() and free() i.e. no compile/run time error.
Question 9
Consider the following C program.
The output of the program is _________
140
120
100
40
Question 10
What is the output of the following C code? Assume that the address of x is 2000 (in decimal) and an integer requires four bytes of memory.
