string的find函数

string的find函数找不到"\"转义字符，需要再添加一个"\\",这样就可以找到了

#include<cstdint>
#include<string>
#include<iostream>
using namespace std;
int main()
{
    string s1 = "`1234567890-QWERTYUIOP[]ASDFGHJKL;ZXCVBNM,.";
    string s2 = "1234567890-=WERTYUIOP[]\\SDFGHJKL;'XCVBNM,./";
    string s3 ;//= "O S, GOMR YPFSU/";//转义字符的使用
    //cin>>s3;
    int x ;
    while(x = getchar() )
    {
        if(x == EOF || x == '\n')
            break;
        if(x == ' ')
        {
            printf(" ");
            continue;
        }
        int pos = s2.find(x);
        printf("%c",s1[pos]);
    }
}
