What will be the output of the following program?
Correct answer (null) (null) & None of above
Run time Error or (null) (null) output varies with compiler
Explanation:
We cannot assign any string constant in the null pointer by strcpy function.
What will be the output of the following program?
Correct Answer 1)Address, Address, 3
Explanation:
Value of k is memory location defined for k.
Value of *k means the content of memory location which address k keeps.
**k will equal to 3.
As
**k = **(&j) = *(*&j) = *j = *(&i) = *&i = i = 3
What will be the output of the following program?
Correct answer 64
Explanation:
we know int is a 4-byte data byte while char is a 1-byte data byte. char pointer can keep the address one byte at a time.
The binary value of 320 is
00000000 00000000 00000001 01000000 (In 64 bit)
So ptr is pointing only the first 8 bit and the Decimal value is 64.
What will be output if you will execute the following c code?
Explanation:
Register variables are stored in the CPU. So it has not a memory address. Hence it is incorrect to write &a.
The output of the following Code:
Answer:
2. 10 10 10 10 10
Explanation:
The default storage class of the local variable is auto. The scope of auto variables is blocked in which it has been declared. When program control goes out of the scope auto variables are dead. So variable I which has been declared inside for loop has scope within a loop and in each iteration, the variable is dead and re-initialized.
