AI代码解释 #include<stdio.h>#include<string.h>intmain(){char buffer[256];FILE*pFile;pFile=tmpfile();do{if(!fgets(buffer,256,stdin))break;fputs(buffer,pFile);}while(strlen(buffer)>1
std::deque其实是分段连续的、介于数组和链表之间的数据结构。这里不进行详细介绍,关于std::deque的介绍,请参见这里。 这些容器都可以成为实现字符串的基础容器。例如,我们的StringBuilder基于std::vector实现;我们的TextPool基于std::deque实现。 也许你有疑问:是的,基于std::vector或者std::deque可以理解,但是,这世...
失败时:返回负数。 /* sprintf example */#include <stdio.h>int main (){char buffer [50];int n, a=5, b=3;n=sprintf (buffer, "%d plus %d is %d", a, b, a+b);printf ("[%s] is a string %d chars long\n",buffer,n);return 0;} [5 plus 3 is 8] is a string 13 chars l...
同样地,也可以用iostream和string标准库,使用标准输入输出操作符来读写string对象: // Note: #include and using declarations must be added to compile this codeint main(){string s; // empty stringcin >> s; // read whitespace-separated string into scout << s << endl; // write s to the ou...

首先,<string> 不再包含 <iterator>。 第二,<tuple> 现在用于声明 std::array 但不包括所有 <array>,这可能中断代码通过以下代码构造的组合:代码具有名为“array”的变量、你具有 using 指令“using namespace std;”,以及你包括了含有 <tuple> 的C++ 标准库标头(如 <functional>),其现在用于声明 std::...
TEST_METHOD(TestClassInit) { std::string name = "Bill"; MyClass mc(name); Assert::AreEqual(name, mc.GetName()); } In the previous example, the result of the Assert::AreEqual call determines whether the test passes or fails. The Assert class contains many other methods to compare ...
