Hi ,
I'm having some probs in this code ....
#include <iostream>
#include <cstdlib>
using namespace std ;
#define SIZE 10
#define EXTRA 50
int main()
{
int *i ;
int j ;
cout << "Size of int is : " << sizeof(int) << endl ;
i = (int *)malloc(SIZE) ;
if(!i)
{
cout << " Allocation error " ;
exit(1) ;
}
cout << "After allocating memory... " << SIZE << endl ;
for(j=0; j<(SIZE+EXTRA); j++)
i[j] = j ;
for(j=0; j<(SIZE+EXTRA); j++)
cout << "\t" << j << " : "<< i[j] << endl ;
free(i) ;
cout << "after freeing memory ..... " << endl ;
for(j=0; j<(SIZE+EXTRA); j++)
cout << "\t" << j << " : "<< i[j] << endl ;
return 0 ;
}
I'm new to dynamic allocation. When i compile this code, some strange things
happen. Here, I allocate 10 new intizer. But assigning value upto 50 intizer
(using EXTRA in for loops) give me no error . Why was that happen since a
I've assigned only 10 ?
Another problem is when I free those memory, still it gives me the same
value as before freeing the memory. Why are those values kept still there
and how ?
I'm currently compiling in Code Blocks with GCC compiler.
Thank in advance :)
