Question

C++ language

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" "" "" "a" "d" "e" O Full Screen 1 code.cpp + New #include <string> 2 using namespace std; 3 4- int flip (string a[], int n) { 5 6 // TODO: your code goes here 7 8 }

C++

#include <iostream>

using namespace std;
//function flips the order of the elements
int flip(string a[], int n)
{
int i = 0,end = n-1;
//loop flips the order of the elements
while (i < end)
{
  
string temp = a[i];
a[i] = a[end];
a[end] = temp;
i++;
end--;
}
//return the n value
return n;
  
}
//main function
int main()
{
//varaible declaration
string a[6] = {"a","b","","c","d","e"};
//calling a function & passing the parameter & returned value is stored into q variable
int q = flip(a , 4);
//printing the returned value
cout<<q;

return 0;
}
