Answer / selvaraj
unwanted memory consumed by a program is called memory leak.
Example:
int fact(void)
{
size=melloc(20);
if(size==NULL)
{
return 1;
}
else
{
return 0;
}
}
Explanation:
size=melloc(20);
here the memory reserved
if(size==NULL)
if memory not available
else means memory available return 0
so, throughout the program the size never used but the program reserved the size. this is called memory leak..
to over come this problem in the else part before return 0; add this statement free(s)
