Does malloc return the actual address or the relative address?

I believe that malloc returns actual address for ordinary pointers and relative addresses for far and huge pointers...is n't it so?

thanks a lot.....

does the value 10 have anything to do with the ascii codes ????

could somebody please explain how this works (Dos based):




int main( void)

{

int i ;

try this (assuming that amt is the length of the input string)




for( i = 0 ; i <= (amt-1) ; i++ )
backwards[ i ] = input[ amt - (i+1) ] ;

backwards[i]= '\0';

for(i=0; i<100; i++)
input3[i] = input[i];




use strcpy() to copy input to input3

syntax : strcpy(input3,input);

solution :

put the statement i=0 outside the loop.( before while)

getch() would be better.

You can calculate arithmetic expressions by converting it from infix to postfix form.

eg. infix : 3+4

postfix : 34 +

The algorithm for this is available in Data structure...

My doubts ....

1.


int main(void)

{

int i;

here's the eg. u wanted



#include<stdio.h>
#include<alloc.h>
typedef struct data
{
int num;
}object;

include this statement in your main program(prime.c)


#include "is_prime.h"

could somebody explain why the following code gives "invalid" as the output?

// code

float w=2.3;
if(w==2.3)
puts("valid");
else
puts("invalid");
