any 1 noe ab make_heap() ?

[issac]

i found an example below; it is ab the make_heap() but, it is not working due to the "print" function.

i doubt ab it. Can any 1 explain more detail to me how to use make_heap()?thx^^

int main(){
int a[]={44,88,33,77,11,99,66,22,55};
print(a,9);
make_heap(a,a+9);
print(a,9);
}

make_heap rearranges the elements between the pointers passed as parameters as a heap, i.e. with the first element being the higher one in value.

in your example (and ignoring the prints), after the call to make_heap, the elements in the a[] array would be rearranged in such a way that a[0] would be 99
