Question1
Write a recursive function that accepts a string object as its argument and prints the string in reverse order. Demonstrate the function in a driver program.
#include
using namespace std;
void print_reverse(string input, int pos){
if (pos < input.length()){
print_reverse(input, pos+1);
cout << input[pos];
}
}
int main()
{
string mystring = "mystring";
cout << "string input is " << mystring << endl;
cout << "reverse is ";
print_reverse(mystring, 0);
cout << endl;
}
Question 2
Write a program that reads a line of text, changes each uppercase let- ter to lowercase, and places each letter both in a queue and onto a stack. The program should then verify whether the line of text is a palindrome (a set of letters or numbers that is the same whether read forward or backward).
#include
#include
#include
using namespace std;
queue readline(std::string input){
queue chars;
for(int i=0; i ...
