Weird outputs

Question

#include <bits/stdc++.h>
using namespace std;
main()
{
int A,B;
int T;
cin >> T;
int total ,even,odd;
while(T--)
{
even=0,odd=0;
int i =1;
for(i;i<=A;i++)
{
if(i%2==0)
{
even1++;
}
else
{
odd1++;
}
}
for(int j=1;j<=B;j++)
{
if(j%2==0)
{
even2++;
}
else
{
odd2++;
}
}
total = even1 ;
cout << even1<<endl;
}
}
