将他们转化为10进制 非16进制数直接输出

方法一：

#include <iostream>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
int main()
{
    char c[1005];
    while(cin>>c)
    {
        if(strcmp(c,"sSN")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"0sSN")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"LMDscandata")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"0")==0)
        {
            cout<<c<<" ";
            continue;
        }
        int len=strlen(c);
        long long i,ans=0,b=1,d;
        for(i=len-1;i>=0;i--)
        {
            if(c[i]>=‘A‘&&c[i]<=‘F‘)
            d=c[i]-‘A‘+10;
            else
            d=c[i]-‘0‘;
            ans+=b*d;
            b*=16;
        }
        cout<<ans<<" ";
    }
    return 0;
}

方法二：

#include <iostream>
#include <string.h>
#include <stdio.h>
using namespace std;
int main()
{
    long long n;
    char c[1005];
    while(scanf("%s",c)!=EOF)
    {
        if(strcmp(c,"sSN")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"0sSN")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"LMDscandata")==0)
        {
            cout<<c<<" ";
            continue;
        }
        else if(strcmp(c,"0")==0)
        {
            cout<<c<<" ";
            continue;
        }
        sscanf(c,"%llx",&n); //从字符串读入一个数
        printf("%lld ",n);
    }
    return 0;
}

把代码存成AC.cpp 把输入文件存成data.in 再新建一个文本文档 输入 AC < data.in > data.out 以后缀名bat保存

运行bat即可生成文件data.out
