Question

C++ ONLY Write a function, int flip(string a[], int n); It reverses the order of the elements of the array and returns n. The variable n will be greater than or equal to zero.

Example:
string array[6] = { "a", "b", "", "c", "d", "e" };
int q = flip(array, 4); // returns 4
// array now contains: "c" "" "b" "a" "d" "e"

Answer 1

C++ Code:

#include <iostream>

using namespace std;

int flip(string arr[],int n){

string *ptr1=arr;

string *ptr2=arr+n-1;

while(ptr1<ptr2){

string temp=*ptr1;

*ptr1=*ptr2;

*ptr2=temp;

ptr1++;

ptr2--;

}

return n;

}

int main() {

string arr[6]={"a","b","","c","d","e"};

cout<<"Before flip: ";

for(int i=0;i<6;i++)

cout<<arr[i]<<" ";

cout<<endl;

flip(arr,4);

cout<<"After flip: ";

for(int i=0;i<6;i++)

cout<<arr[i]<<" ";

cout<<endl;

}
