For loop

can i use the for loop like this in accessing the 2-d array.

   for(u=0;u<=4;u++)
     {
       for(v=v1;;)
          {
             arr[u][v] += 1;
           }
     }

bcos in the second for loop i want to do the increment in some other function.

but the c51 shows an endless loop on executing the second for loop.

can i use only one for loop and no for loop for v since this v i want to increment in some other function?
