Function overloading

C++ also contains various other improvements, including references, which are related to pointers, and function overloading. These two additions are described in Sections A and B, below, and then the remaining sections detail the class data type, which is the focus of object-oriented programming using C++.

Every synthesis tool vendor will undoubtedly supply the same or very similar functions and so their use here is justified. It also enables the subject of opera r and function overloading to be introduced by an example before it is discussed in detail in the next chapter. 

Operators and functions can be overloaded. This involves the substitution of one version of an operator or function for a different one with an identical name. RIPPLE is an example of an overloaded function where the + operator function overloads the built-in + operator functions. 

The third architecture RIPPLES takes this direct access a step further and dispenses with the Use clause altogether. Both the SIGNED type declaration and the RIPPLE function are accessed directly. This architecture accesses the second RIPPLE function, overloading the first by the number of parameters that are supplied. This is only one way of achieving function overloading Box 6.8 discusses these methods further. Another approach selects the appropriate function by the type of the parameters that are supplied. 

The second function overloads the first by changing the type (or subt3Tpe in this case) of the arguments in the parameter list. The third overloads the first by changing the number of arguments in the parameter list and it overloads ffie second by changing both the t e and number of arguments. Calls to each function are illustrated below. 

Available Chlorine Test. The chlorine germicidal equivalent concentration test is a practical-type test. It is called a capacity test. Under practical conditions of use, a container of disinfectant might receive many soiled, contaminated instniments or other items to be disinfected. Eventually, the capacity of the disinfectant to serve its function would be overloaded due to reaction with the accumulated organic matter and organisms. The chlorine germicidal equivalent concentration test compares the load of a culture of bacteria that a concentration of a disinfectant will absorb and still kill bacteria, as compared to standard concentrations of sodium hypochlorite tested similarly. In the test, 10 successive additions of the test culture are added to each of 3 concentrations of the hypochlorite. One min after each addition a sample is transferred to the subculture medium and the next addition is made 1.5 min after the previous one. The disinfectant is then evaluated in a manner similar to the phenol coefficient test. For equivalence, the disinfectant must yield the same number of negative tubes as one of the chlorine standards. 

Line Starters and Combination Starters A line starter consists of a contactor (motor-starting switch) and motor-overload relays, (Contactors are capable of canving and interrupting normal motor-starting and -running currents they are not, hovv ever, normally capable of interrupting short-circuit currents. They must be backed up by fuses or a circuit breaker for this function,...

Evaluation of the effects of overpressure attributable to the loss of a particular utility supply must include the chain of developments that could occur and the reaction time involved. In situations where fluid flow stops due to failure of its utility supply, but is in parallel with equipment having a different energy source, credit may be taken for the unaffected and functioning equipment to the extent that operation is maintained and the operating equipment will not trip out due to overloading. 

During tiie ongoing assessment, tiie nurse assesses the respiratory status every 4 hours and whenever tiie drug is administered. The nurse notes the respiratory rate, lung sounds, and use of accessory muscles in breathing, hi addition, tiie nurse keeps a careful record of the intake and output and reports any imbalance, which may indicate a fluid overload or excessive diuresis. It is important to monitor any patient with a history of cardiovascular problems for chest pain and changes in the electrocardiogram. The primary health care provider may order periodic pulmonary function tests, particularly for patients with emphysema or bronchitis, to help monitor respiratory status. 

Older adults are at increased risk for fluid overload because of the increased incidence of cardiac disease and decreased renal function that may accompany old age. Careful monitoring for signs and symptomsof fluid overload (see Table 58-2) isextremely important when administering fluids to older adults... 

Recent studies by Crompton et al. have shown that oxidant stress may open a Ca-sensitive, non-selective pore in the inner mitochondrial membrane that is blocked by cyclosporin A (Crompton, 1990 Crompton and Costi, 1990). This pore opening results in massive mitochondrial swelling, dissipation of the transmembrane proton gradient and disruption of mitochondrial energy production (Crompton et al., 1992). Since mitochondria may play a role as a slow, high-capacity cytosolic calcium buffer (Isenberg et al., 1993), disruption of mitochondrial function may also contribute to calcium overload and cell injury. 

Heart failure is a clinical syndrome characterized by a history of specific signs and symptoms related to congestion and hypoperfusion. As HF can occur in the presence or absence of fluid overload, the term heart failure is preferred over the former term congestive heart failure. Heart failure results from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood.1 Many disorders such as those of the pericardium, epicardium, endocardium, or great vessels may lead to HF, but most patients develop symptoms due to impairment in left ventricular (LV) myocardial function. 

Dopamine is most commonly reserved for patients with low systolic blood pressures and those approaching cardiogenic shock. It may also be used in low doses (less than 3 mcg/kg per minute) to improve renal function in a patient with inadequate urine output despite high filling pressures and volume overload, although this indication is controversial.
