getnum是什么函数

c++的内联函数详解:内联函数是代码被插入到调用者代码处的函数。如同 #define 宏,内联函数通过避免被调用的开销来提高执行效率,尤其是它能够通过调用(“过程化集成”)被编译器优化。 内联函数和宏很类似,而区别在于,宏是由预处理器对宏进行替代,而内联函数是通过编译器控制来实现的。而且内联函数是真正的函数,只是在需要用到的时候,内联函数像宏一样的展开,所以取消了函数的参数压栈,减少了调用的开销。你可以象调用函数一样来调用内联函数,而不必担心会产生于处理宏的一些问题。 声明内联函数看上去和普通函数非常相似: void f(int i, char c); 当你定义一个内联函数时,在函数定义前加上 inline 关键字,并且将定义放入头文件: inline void f(int i, char c) { // ... } 任何在类的说明部分定义的函数都会被自动的认为是内联函数。 内联函数必须是和函数体申明在一起,才有效。像这样的申明Inline Tablefunction(int I)是没有效果的,编译器只是把函数作为普通的函数申明,我们必须定义函数体。 Inline tablefunction(int I) {return I*I}; 这样我们才算定义了一个内联函数。我们可以把它作为一般的函数一样调用。但是执行速度确比一般函数的执行速度要快。 我们也可以将定义在类的外部的函数定义为内联函数,比如: Class TableClass{  Private:   Int I,j;  Public:   Int add() { return I+j;};   Inline int dec() { return I-j;}   Int GetNum(); } inline int tableclass::GetNum(){ return I; } 上面申明的三个函数都是内联函数。在C++中,在类的内部定义了函数体的函数,被默认为是内联函数。而不管你是否有inline关键字。 内联函数在C++类中,应用最广的,应该是用来定义存取函数。我们定义的类中一般会把数据成员定义成私有的或者保护的,这样,外界就不能直接读写我们类成员的数据了。对于私有或者保护成员的读写就必须使用成员接口函数来进行。如果我们把这些读写成员函数定义成内联函数的话,将会获得比较好的效率。 Class sample{  Private:   Int nTest;  Public:   Int readtest(){ return nTest;}  Void settest(int I) {nTest=I;} } 当然,内联函数也有一定的局限性。就是函数中的执行代码不能太多了,如果,内联函数的函数体过大,一般的编译器会放弃内联方式,而采用普通的方式调用函数。这样,内联函数就和普通函数执行效率一样了。 [size=-1]

getnum是什么函数

getnum函数一般用来得数组的长度.如:public static int getNum(int a[])一个数组,数组里的元素是int,就当正常array类型用,用length作为长度,遍历就行 for(int i = 0 ; i<a.length ; i++){ a[i]...... } 希望对你有帮助,谢谢.

你好同学,这句话说反了,单词颠倒,应该这么说:Nice to meet you.意思是:见到你很高兴。希望能帮到你。

vietnam英语作文600字

Vietnam Officially the Socialist Republic of Vietnam (SRV; ), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants as of 2014, it is the world"s 13th-most-populous country, and the eighth-most-populous Asian country. The name Vietnam translates as "Southern Viet" (synonymous with the much older term Nam Viet); it was first officially adopted in 1802 by Emperor Gia Long, and was adopted again in 1945 with the founding of the Democratic Republic of Vietnam under Ho Chi Minh. The country is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and the South China Sea to the east.[8] Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976.Vietnam was part of Imperial China for over a millennium, from 111 BC to AD 938. The Vietnamese became independent from Imperial China in 938, following the Vietnamese victory in the Battle of Bu1ea1ch u0110u1eb1ng River. Successive Vietnamese royal dynasties flourished as the nation expanded geographically and politically into Southeast Asia, until the Indochina Peninsula was colonized by the French in the mid-19th century. Following a Japanese occupation in the 1940s, the Vietnamese fought French rule in theFirst Indochina War, eventually expelling the French in 1954. Thereafter, Vietnam was divided politically into two rival states, North and South Vietnam. Conflict between the two sides intensified, with heavy intervention from the United States, in what is known as the Vietnam War. The war ended with a North Vietnamese victory in 1975.Vietnam was then unified under a communist government but remained impoverished and politically isolated. In 1986, the government initiated a series of economic and political reforms which began Vietnam"s path towards integration into the world economy. By 2000, it had established diplomatic relations with all nations (except South Sudan). Since 2000, Vietnam"s economic growth rate has been among the highest in the world, and, in 2011, it had the highest Global Growth Generators Index among 11 major economies.Its successful economic reforms resulted in its joining the World Trade Organization in 2007.However, regardless of the advancements that have been made in recent years, the country still experiences high levels of income inequality, disparities in access to healthcare, and a lack of gender equality.
