将c字符串数组复制到std :: string向量中

Question

我需要将c数组字符串的元素存储在向量中。

基本上我需要将c数组的所有元素复制到vector<std::string>。

#include<vector> 
#include<conio.h> 
#include<iostream> 

using namespace std; 

int main() 
{ 
    char *a[3]={"field1","field2","field3"}; 

    //Some code here!!!! 

    vector<std::string>::const_iterator it=fields.begin(); 
    for(;it!=fields.end();it++) 
    { 
     cout<<*it++<<endl; 
    } 
    getch(); 
} 

任何人都可以帮我把c数组元素存储到一个向量中吗？

这下面的代码被倾倒的核心!!请帮助

int main() 
{ 
    char *a[3]={"field1","field2","field3"}; 
    std::vector<std::string> fields(a, a + 3); 

    vector<std::string>::const_iterator it=fields.begin(); 
    for(;it!=fields.end();it++) 
    { 
     cout<<*it++<<endl; 
    } 
    getch(); 
} 

Answer 1

std::vector<std::string> fields(a, a + 3); 

Answer 2

您使用Insert方法将内容添加到一个载体。看看样品片段从这里： http://www.cplusplus.com/reference/stl/vector/insert/

Answer 3

std::vector<std::string> blah(a, a + LENGTH_OF_ARRAY) 

Answer 4

#include<vector> 
// #include<conio.h> 
#include<iostream> 
#include <iterator> 
#include <algorithm> 

using namespace std; 

int main() 
{ 
    const char *a[3]={"field1","field2","field3"}; 

    // If you want to create a brand new vector 
    vector<string> v(a, a+3); 
    std::copy(v.begin(), v.end(), ostream_iterator<string>(cout, "\n")); 

    vector<string> v2; 
    // Or, if you already have an existing vector 
    vector<string>(a,a+3).swap(v2); 
    std::copy(v2.begin(), v2.end(), ostream_iterator<string>(cout, "\n")); 

    vector<string> v3; 
    v3.push_back("field0"); 
    // Or, if you want to add strings to an existing vector 
    v3.insert(v3.end(), a, a+3); 
    std::copy(v3.begin(), v3.end(), ostream_iterator<string>(cout, "\n"));
