如何在c++中比较多个字符串

how do you compare multiple strings in C++

我正在做一个硬件任务，我在这部分卡住了。代码如下:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <iostream>
using namespace std;

std::string stringSmallest(std::string s1, std::string s2, std::string s3, std::string s4, std::string s5 );

int main(int argc, char)
{
   std::string sSmallest = stringSmallest("hi", "wassup", "hello", "good","bye");
    printf("strings: %i", sSmallest); 
    std::cin.get();
    return 0;
}
std::string stringSmallest(std::string s1, std::string s2, std::string s3, std::string s4, std::string s5 ){
    std::string strSmallest = 0;
    if (strSmallest.compare(s1)<0)
        strSmallest = s1;
    if (strSmallest.compare(s2)<0)
        strSmallest = s2;
    if (strSmallest.compare(s3)<0)
        strSmallest = s3;
    if (strSmallest.compare(s4)<0)
        strSmallest = s4;
    if (strSmallest.compare(s5)<0)
        strSmallest = s5;
    return strSmallest;
}

我想做的是用最小的字符串创建一个字符串。

试试这个

std::string stringSmallest(std::string s1, std::string s2, std::string s3, std::string s4, std::string s5 )
{
std::string strSmallest = s1;
if (strSmallest.compare(s2)>0)
    strSmallest = s2;
if (strSmallest.compare(s3)>0)
    strSmallest = s3;
if (strSmallest.compare(s4)>0)
    strSmallest = s4;
if (strSmallest.compare(s5)>0)
    strSmallest = s5;
return strSmallest;
}
