急! C++中stack,pop的操作
pop返回值类型是void(error C2440: '=' : cannot convert from 'void' to 'char'明确指出了这一点)。因为如果返回非void类型,返回时会调用复制构造函数,如果其中抛出异常就会在未完成构造的情况下中断且无法简单回滚,无法保证容器的异常安全性,所以在std::stack的设计时就考虑把返回栈顶元素的功能交给其它成员函数实现,这个成员函数的原型是const typename std::stack::value_type& std::stack::top() const;,在std::stack的类作用域内简作const value_type top() const;,其中value_type是元素类型。 因此s2[len]=st.pop(); 是错的。应该使用s2[len]=st.top();st.pop();另外既然使用string,直接用==和!=比较就可以了。strcmp的原型是int strcmp(const char*, const char*);,不接受string类型的参数,所以产生错误。或者用string的成员函数c_str得到C风格字符串表示:strcmp(s1.c_str(),s2.c_str())。也可以不用string而用char数组,这样就可以直接strcmp。↑2011-3-20 20:36。----er...才注意到LZ用string而用的是operator[]……注意string和内置数组、vector、map等一样,operator[]是不进行越界检查的(上述除了内置数组外都有成员函数at完成相同功能并会在之前检查是否越界,如果越界抛出out_of_range异常)……而LZ初始化后string自身管理的内存就已经确定了(因为没进行调用会改变内存大小的操作),虽然通常是16字节,但不见得会有保证(取决于模板类std::basic_string的具体实现;这里LZ忘了len++和末尾置零。。。我这里改正之后还是有问题,应该就是这个原因)。对于string还是直接用+=在末尾增加内容比较好,如果内存不够用会自动分配,而且也比较直观。如果一定要用[]最好自己用数组或者指针分配空间。改好的代码(只看第二个while循环就行):#include #include #include using namespace std;int main(){int len=0;string s1;string s2;stack st;cout<<"请输入要判断的字符串: ";cin>>s1;while(s1[len]!=' '){st.push(s1[len]);len++;}len=0;while(st.size()!=0){s2+=st.top();st.pop();}if(s1==s2)cout<<"该字符串为一个回文";return 0; }
上面的已经说的很清楚了,对于c++的stack,pop指的是移除栈顶的元素,而top是取出栈顶元素的内容但是不移除它。因此你这里想做的pop实际上是上面两个操作的结合,因此你应该写s2[len] = st.top(); st.pop();这样就对了。此外对于字符串,C风格的字符串类型是char*,对于char*类型的操作定义在或者中,函数的形式大多为str...,例如你的strcmp;而C++风格的是string类,定义在中,对于string类有很多中现成的方法,对于比较它们是否相等,只需要s1 != s2这种和其他变量相同的写法就可以了。
pop无返回值,用top,再pop。 strcmp不能对string变量,改为strcmp(s1.c_str(),s2.c_str()),可以直接s1 != s2。
strcmp这个函数原形是 int strcmp(char *,char*),你传入一个string的对象进去是不行的。

泰戈尔的“只有经历地狱般的磨练才能练出创造天堂的力量,只有流过血的手指才能弹出世间的绝唱”英文翻译
泰戈尔的“只有经历地狱般的磨练才能练出创造天堂的力量,只有流过血的手指才能弹出世间的绝唱”英文翻译:Only the experience of hell can exercise the power to create heaven, only through the blood of the fingers can pop out of the world这句诗出自泰戈尔的《飞鸟集》。《飞鸟集》是印度诗人泰戈尔创作的诗集,它包括325首清丽的无标题小诗,首次出版于1916年。这些诗的基本题材多为极其常见事物,不外乎小草、落叶、飞鸟、星辰、河流等等。扩展资料:创作背景《飞鸟集》创作于1913年,初版于1916年完成。《飞鸟集》其中的一部分由诗人译自自己的孟加拉文格言诗集《碎玉集》(1899),另外一部分则是诗人1916年造访日本时的即兴英文诗作。诗人在日本居留三月有余,不断有淑女求其题写扇面或纪念册。诗人曾经盛赞日本俳句的简洁,他的《飞鸟集》显然受到了这种诗体的影响。
只有经历地狱般的磨练才能练出创造天堂的力量,只有流过血的手指才能弹出世间的绝唱. 翻译为英文:Only through the hellish hone can have the power to create heaven, only through the Bleeding fingers can play the tune of the world.主要词汇:1, hellish 地狱般的例句: You are the one shining light in this hellish hole.你是这个地狱般洞穴中一道闪亮的光。2, hone 磨练例句: His body is honed and kept in trim with constant exercise.他经常运动,以锻炼身体和保持身材。3, create heaven 创造天堂例句: Every time we extend loving kindness,Tolerance and understanding to others, At that time we create heaven.当我们把关爱、仁慈、宽容和体谅扩及于别人时,我们就创造了天堂。4,Bleeding fingers 流血的手指例句: Scarlett's bleeding fingers sought her father's hand urgently. 思嘉迫不及待地用几个流血的手指摸索父亲的手。
Only through hell of a hone to create the power of heaven LianChu, only through the blood to pop up to the swan song of the fingers
Only experienced the hell of torture, have conquered the power of heaven. Only through the blood of the fingers can last popup world
Only the experience of hell can exercise the power to create heaven, only through the blood of the fingers can pop out of the worl
