Consecutive elements

PROBLEM :

For a given string delete the elements which are appearing more than once consecutively. All letters are of lowercase.

Input:
The first line contains an integer 'T' denoting the total number of test cases. In each test cases,  a string will be inserted.

Output:
In each seperate line the modified string should be output.

Constraints:
1<=T<=31
1<=length(string)<=100

Example:

Input:
1
aababbccd

Output:
ababcd

SIMPLE c++ IMPLEMENTATION :
--------------------------------------------------------------------------------

#include<iostream>
using namespace std;
#include<string.h>
string Consecutive_elements(string ) ;
int main()
 {
int t ;
string str ;
cin>>t ;
while(t--)
{
   cin>>str ;
   str=Consecutive_elements(str) ;
   cout<<str<<endl ;
}
return 0;
}

string Consecutive_elements(string str)
{
    int l,i=0 ;
    l=str.length() ;
   
    while(str[i]!='\0')
    {
        if(str[i]==str[i+1])
        str.erase(i,1) ;
else
        i++ ;
    }
    return str ;
}
