Cpp Programming Quiz 174 – Which of the following function / types of function cannot have default parameters?

Question: Which of the following statement is correct about the program given below?

#include
class BixArray
{
int array[3][3];
public:
BixArray(int arr[3][3] = NULL)
{
if(arr != NULL)
for(int i = 0; i < 3; i++) for(int j = 0; j < 3; j++) array[i][j] = i+j; } void Display(void) { for(int i = 0; i < 3; i++) for(int j = 0; j < 3; j++) cout<< array[i][j] << " "; } }; int main() { BixArray objBA; objBA.Display(); return 0; }

[A].The program will report error on compilation.
[B].The program will display 9 garbage values.
[C].The program will display NULL 9 times.
[D].The program will display 0 1 2 1 2 3 2 3 4.

Answer: Option B

[A]. int Sum(int a, int b = 2, int c = 3);
[B]. int Sum(int a = 5, int b);[C]. int Sum(int a = 0, int b, int c = 3);
[D]. Both B and C are incorrect.

Answer: Option D

Question: What will be the output of the following program?

#include
class IndiaBix
{
char txtMsg[50];
public:
IndiaBix(char *str = NULL)
{
if(str != NULL)
strcpy(txtMsg, str);
}
int BixFunction(char ch);
};
int IndiaBix::BixFunction(char ch)
{
static int i = 0;
if(txtMsg[i++] == ch)
return strlen((txtMsg + i)) - i;
else
return BixFunction(ch);
}
int main()
{
IndiaBix objBix("Welcome to IndiaBix.com!");
cout<< objBix.BixFunction('t'); return 0; }

[A].6
