assigning numbers to variables with already assigned values

hi all,
is there anyway to remove a value of a variable with something like void so input can be assigned to it again?
what i mean is 
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
   e = 0;
   while (e <= m) { 
         in >> x >> y;   
                if (0<x<= n, 0<y<=n) {     
                        quadrant1++;
		} 
		else if ((n+1)<=x<=2*n, 0<y<=n) {
			quadrant2++;
		}
		else if (0<x<=n, (n+1)<=y<=2*n) {
			quadrant3++;
		}
		else quadrant4++; {}
		         e++;
		}

is there a way i can remove the values of x and y to get new input.
its getting input from a seperate file other than that on my computer.
dont worry about the superflous lines i have in there either.
thanks for the help

Why does the variable have to be empty? You can just overwrite the value.

does that while loop overwrite it, or does it use the old value?
