Template and demerits
This is because they are declared as templates using syntax not unlike the one presented below:. Foo ;. Defining member functions of a template class is somewhat like defining a function template, except for the fact, that you use the scope resolution operator to indicate that this is the template classes' member function. The one important and non-obvious detail is the requirement of using the template operator containing the parametrized type name after the class name.
The following example describes the required syntax by defining functions from the example class above. As you may have noticed, if you want to declare a function that will return an object of the parametrized type, you just have to use the name of that parameter as the function's return type. Advantages and disadvantages. Some uses of templates, such as the max function, were previously filled by function-like preprocessor macros.
Both macros and templates are expanded at compile time. Macros are always expanded inline; templates can also be expanded as inline functions when the compiler deems it appropriate. Thus both function-like macros and function templates have no run-time overhead. However, templates are generally considered an improvement over macros for these purposes. Templates are type-safe. Templates avoid some of the common errors found in code that makes heavy use of function-like macros.
Perhaps most importantly, templates were designed to be applicable to much larger problems than macros. The definition of a function-like macro must fit on a single logical line of code. There are three primary drawbacks to the use of templates. First, many compilers historically have very poor support for templates, so the use of templates can make code somewhat less portable. Second, almost all compilers produce confusing, unhelpful error messages when errors are detected in template code.
This can make templates difficult to develop. Third, each use of a template may cause the compiler to generate extra code an instantiation of the template , so the indiscriminate use of templates can lead to code bloat, resulting in excessively large executables. The other big disadvantage of templates is that to replace a define like max which acts identically with dissimilar types or function calls is impossible.

This process takes time and can be especially challenging if write a concluding sentence about the second disadvantage. All things considered, Write a general one-sentence summary of the topic. You need to weigh up the pros of write two advantages here which you wrote in the second and third paragraph , and the cons of write two disadvantages here which you wrote in the third and fourth paragraph.
Personally, I believe the benefits in terms of write the same 2 advantages using different words eventually outweigh any negatives. These days, more and more people are going to other countries for significant periods of time, either to find a job or to study.
There are clearly many benefits to doing this, but people who live abroad can also face some difficulties. Discuss the advantages and disadvantages of living and working in a foreign country.
Give reasons for your answer and include any relevant examples from your own knowledge or experience. Write at least words. Nowadays, taking a here out to live or study abroad is becoming increasingly popular.
For many people, especially young adults, the chance to spend an extended period of time overseas is an attractive one. In this essay, I will discuss some of the reasons why moving abroad is so popular and some of the challenges to be overcome.
One of the main positives of heading overseas is that it broadens your horizons. What I mean by this is that you have the chance to meet people from different cultural backgrounds and learn to cope with foreign customs and food. This can make you more rounded as a person.
Secondly, moving abroad can lead to a better quality of life. Take British people for an example. Thousands of people from the UK move to Spain and Australia every year. These countries have warmer climates and encourage a better work-life balance. In addition, by living Overseas, you can gain qualifications and language skills, which may improve promotion prospects on your return. Turning to the other side of the argument, culture shock is a major problem.
Many people who take a year out find it hard to cope with the language barrier, the food, and general cultural differences. This often leads to homesickness and in some cases a sense of isolation. Another issue is that it can be difficult to start a new life from scratch.
