摘要：互换数值主要是出现实参和虚参问题，下面是小结下。第一种使用指针方法，来互换内容//使用指针互换指针内容值voidswap(int*a,int*b){inttemp=*b;*b=*a;*a=temp;}第二种可以通过引用来互换数值//使用引用来互换值voidswap1(int&a,int&b){inttemp=b;b=a;a=temp;}下面给出互换指针方法，主要是通过引用来互换。//互换指针值非内容voidptrswap(int*&a,int*&b){int*temp=b;b=a;a=temp;}下面是指向函数的指针实现以及定义//指向函数的指针intmin(i 阅读全文

摘要：erase函数的原型如下：（1）string& erase ( size_t pos = 0, size_t n = npos );（2）iterator erase ( iterator position );（3）iterator erase ( iterator first, iterator last );也就是说有三种用法：（1）erase(pos,n); 删除从pos开始的n个字符，比如erase(0,1)就是删除第一个字符（2）erase(position);删除position处的一个字符(position是个string类型的迭代器)（3）erase(first,la 阅读全文
