At the end of the while loop you are repeating:
mid=(s+(e-s))/2;
which is the same value you started with. Try incrementing the value of mid (mid++). But there still seem to be some possible logic errors.

It helps to use extra cout statements thruout the code to follow the value of s, and possibly e as well.

Answer 2

I tried to Resolve error u missing parentheses and return statement

int findOdd(vector<int> arr)
{
int s=0;
int e= arr.size()-1;
int mid = (s+(e-s))/2;

while(s<=e)
{
if(s==e)
{
return arr[s];
}

//mid is evn
if(mid%2==0)
{
if(arr[mid]==arr[mid+1])
{
s=mid+2;
}
else{
e=mid;
}
}
else{
if(arr[mid]==arr[mid-1])
{
s=mid+1;
}
else{
e=mid-1;
}

return mid=(s+(e-s))/2;
}
}
return 0;
}
