How the system got to understand &cmp

#1

why &cmp are we using this … why not &compare how willthe system relate both of them if there are multiple functions present

#2

@suryansh771 you always pass the address of your compare function so the system will know exactly which compare function to use.
for eg

bool cmp(int val1, int val2) {
   return val1 > val2;
}

sort(arr, arr+n, cmp); //here you pass the address of the comparator function you wish to use
