CS201 Midterm Question No. 18:

( Marks: 10 )

Write a recursive function that takes three arguments (an integer array, starting subscript ‘s’ and

ending subscript ‘e’ ).

In first recursive call, the function should display the array from subscript ‘s’ (s = 0) to ‘e’ (e =

size of array). In each successive call, the function should print the array from index s+1 to e. T

function should stop processing and return when starting subscript becomes equal to ending

subscript.

For example, if user enters values for array 2, 3, 4, 5, 6 then the recursive function must display the

following output.

2 3 4 5 6

3 4 5 6

4 5 6

5 6

6

Answer:

#include ;

void PrintArray(int arrayInput[], int &s, int &e);

main ( )

{

int pause;

int TestArray [6] = {1,2,3,4,5,6};

int StartPoint = 0;

int EndPoint = 5;

PrintArray(TestArray , StartPoint, EndPoint);

cout<<"\n";

PrintArray(TestArray , StartPoint, EndPoint);

cout<<"\n";

PrintArray(TestArray , StartPoint, EndPoint);

cout<<"\n";

PrintArray(TestArray , StartPoint, EndPoint);

cout<<"\n";

PrintArray(TestArray , StartPoint, EndPoint);

cout<<"\n";

PrintArray(TestArray , StartPoint, EndPoint);

cin >> pause;

}

void PrintArray(int arrayInput[], int& s, int& e)

{

for (int i = s; i<= e; i++)

{

cout<< arrayInput[i];

}

s=s+1;

}
