| 1. | What does this program
do:
#include <iostream.h>
void mystery1(char * , const char * );
int main()
{
char string1[80], string2[80];
cout << "Enter two strings: ";
cin >> string1 >> string2;

do?
#include <iostream.h>
int mystery3(const char * , const char * );
int main()
{
char string1[80], string2[80];
cout << "Enter two strings: ";
cin >> string1 >> string2;
cout << "The result is " << mystery3(string1, string2) << endl;

return (0);
return(1);

| 4. | Write a program with a
function
named flip_string, that will receive a string and reverse it.
Display
the string in main() before the function call, and display the
reversed
string after the function call. Note: you must use only one character
array to
store the string; do not create a new array to store the reversed
string |
