Predict the Output

What is the output of the following programs?

A) #include

using namespace std;

int function(int);

int main()

{

int x = 10;

cout << function(x) << endl;

return 0;

}

int function(int num)

{

if (num <= 0)

return 0;

else

return function(num - 1) + num;

}

B) #include

using namespace std;

void function(int);

int main()

{

int x = 10;

function(x);

return 0;

}

void function(int num)

{

if (num > 0)

{

for (int x = 0; x < num; x++)

cout << '*';

cout << endl;

function(num - 1);

}

}

C) #include

}

void function (string str, int pos)

{

if (pos < str.length())

{
