| I use turbo C which allocates 2 bytes for integers and 4
bytes for long. I tried to declare array of size 500000 of
long type using the following code...
long *arr;
arr=(long *)(malloc)(500000 * sizeof(long));
It gives a warning that "Conversion may lose significant
digits in function main"...
And the resulting array size was very less around 8400 as
compared to 500000. Any suggestions will be welcomed....
