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?
"c51 shows an endless loop on executing the second for loop"
for(v=v1;;)
Of course it does - because it is an endless loop! You haven't specified any exit condition!
You need to add an exit condition - either in the 'for' clause, or a break somewhere in the body of the loop.
Note that the 3 expressions within a 'for' clause don't all have to use the same variable; eg,
for( w=0; x<y; ++z )
can i do the increment of the 'y' of arr[x][y] in another function?
so that only one for loop is executing for 'x' not for 'y'.
i think u can see the 2D array i have written.
The column increment i want to do separate function not inside the row for loop.
"can i do the increment of the 'y' of arr[x][y] in another function?"
Of course you can!
I think you need to go back to your 'C' textbook, and thoroughly read the description of the 'for' loop, and precisely what the 3 expressions in the 'for' clause actually do...
for( w=0; x<y; z++ ) { : : }
is equivalent to
for( w=0; x<y; ) { : : z++; }
Thank you.
Since i made mistake in some other place it had affected the for loop.
Thats y i also confused.
Anyway thank you for ur message.
