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....

Answer / anshu ranjan

I want to make a point here...I am not sure whether there is a limit to amount of memory that you can allocate using malloc...

I used this code in a program and it ran perfectly fine...

--------------
char **a;
int **val;

a =(char **) malloc ( 1000 * sizeof *a );
for ( i = 0; i < 1000; i++ )
a[i] =(char *) malloc ( 1000 * sizeof *a[i] );
val =(int **) malloc ( 1000 * sizeof *val );
for ( i = 0; i < 1000; i++ )
val[i] =(int *) malloc ( 1000 * sizeof *val[i] );

Answer / vignesh1988i

good morning to you.....

here what i suggest is that , at the time of dynamic memory allocation the memory would not been in the position to allocate that much of huge memory at a single instance...... UR MEMORY WILL BE INCAPABLE IF U TRY TO ALLOCATE A HUGE AMOUNT LIKE ABOVE FOR UR USE.......

u try this.... you declare an array size of 200 or 300... this will give a warning that MEMORY FULL........ the one of the disadvantages in C is that we cant balance a very large amount of data's which are outside the range .... so only we will go for DATA BASE.......

hope this helps u for getting some ideas.......

thank u
