equal()

Returns true if the two sequences are equal for the number of elements contained within the first container. By default, the equality operator is used. Alternatively, a binary function object or pointer to function can be supplied.

int ia2[] = { 1,1,2,3,5,8,13,21,34 }; 


res = equal( ia1, ia1+7, ia2 ); // true 


res = equal( ia1, ia1+7, ia2, equalAndOdd() ); // false
