loop is repeated, and • is not separated from the loop by a function interface?result_type function_name ( parameter_list ) interface { // preconditions… implementation; // postconditions… } The The calling function is responsible for the top part of the interface. The called function is responsible for the bottom part of the interface.😈 Let’s call that sort of reason a local reason. Does the ensure that a and b remain stable during the operation. bool operator==( const int a, const int b ) interface { extend_stability a, b; discern a, b; implementation; transfer_stability result; discern result;
