• 我怎样才能把许多慈善机构和Put Them Into One String
原标题:How Can I Take Many Chars and Put Them Into One String

我说,我从来就没有学到这一点。 我以前从未这样做过。 我看到了<代码>strcat(S1,S2)的使用,但此处适用的是哪里?

我能做这样的事情。

string all_possible_strings[10]; 
char jumbled_chars[] = "ABCDEFG";
all_possible_strings[1] = jumbled_chars[0] << jumbled_chars[1] 
                              << jumbled_chars[2] << jumbled_chars[3] 
                              << jumbled_chars[4];

我想要做的是制定一项方案,使其所有可能的变迁不会产生任何影响。

问题回答
#include <iostream>
#include <string>

using namespace std;

int main()
{
        string theString = "";
        char a =  a ;
        char b =  b ;
        const char* c = "cdefghijklmnopqrstuvwxyz";

        theString += a;
        theString += b;
        theString += c;

        cout << theString;
        return 0;
}

这印刷了整个字母。

使用<条码>应用功能或<条码>operator+=上载<条码>以下: http://www.sgi.com/tech/stl/basic_string.html”

如果jfalld_chars已按你的意愿顺序排列,那么你就只能建造像你那样的雕像。

all_possible_strings[counter] = std::string(jumbled_chars, 5);

<>Update:

Ok, 这里提出一些建议。 不要把你的扼杀放在一个阵列中,而是使用<代码>std:vector。

std::vector<std::string> possible_strings;
std::string jumbled_chars; //This could be a char[] or char* or whatever

我的左边是,我们如何把扼杀作为读者的一种行动,完全归结在一起。 但是,请您在<代码>w、>、xyz>>>、w-z_w-z_index of jdrd_chars:

std::string str = "";
str += jumbled_chars[w];
str += jumbled_chars[x];
str += jumbled_chars[y];
str += jumbled_chars[z];

possible_strings.push_back(str);
