| 1. What is Operator, Operand, Expression, Statement in 'C'? |
| 2. What is polymorphism? |
|
|
| 3. What is operator overloading? |
| 4. What are templates? |
| 5. Declare a void pointer. |
| 6. Declare a function pointer which takes a pointer to char as an argument and returns a void pointer. |
| 7. Type-define a function pointer which takes a int and float as parameter and returns a float *. |
|
|
8. What does the following C statement do?
while(*c++ = *d++);
assuming c and d are pointers to characters.
|
| 9. How do you call a C module within a C++ module.
|
| 10. What is the difference between run time binding and compile time binding? Discuss. |
| 11. Compare and contrast C++ and Java. |
| 12. Why does C/C++ give better run-time performance then Java? |
|
|
| 13. Does C++ come with in-built threading support. |
| 14. Class A derives B derives C. All have foo(). I cast C to A and call foo(). What happens? |
| 15. All classes A, B, C have default constructor, foo() that calls parent foo() and allocates 100 bytes to their own private local variable, and a destructor that frees the 100 bytes. I create a C object and then destroy it. What's the problem? Did all the memory get freed? What if I create C, cast to A, and then destroy it. How would I make sure memory is freed? (destructor must be virtual" and each destructor must call parent destructor)" |
| 16. What errors are caught at compile time vs link time? |
17. What is the value of "a" after this?
int (*a) [10];
a++;
|
18. What is wrong with this?
main(){
int *ptr;
*ptr=10;
}
|
19. Given int n, i=10, j=20, x=3, y = 100;
What is the value of n and y at the end of each of the following expressions?
a) n = (i > j) && (x < ++y);
b) n = (j - i) && (x < y++);
c) n = (i < j) || (y+=i);
|
20. int x = 5;
int y = 7;
What is the value of x and y after the expression y+=x++;
|
| 21. What's the difference between C and C++? |
| 22. What does Public and Private mean in C++ |
| 23. Is it possible to keep 2 stacks in a single array, if one grows from position one of the array, and the other grows from the last position. Write a procedure PUSH(x,s) that pushes element x onto stack S, where S is one or the other of these two stacks. Include all necessary error checks |
