我不确定如何使用 strtok 来分隔令牌 [英] Im not sure how to use strtok to separate tokens

问题描述

我正在使用 C 语言并想尝试执行以下操作.所以用户按以下格式输入日期

I am messing around with C and want to try and do the following. so a User enters a date in the following format

Saturday, July 8, 2017, 22:14:10

并且我想使用 strtok 来分隔标记并显示输出如下，

and I want to Use strtok to separate tokens and display output as follows,

Month: July
Day: 8
Year: 2017
Hour: 22
Minute: 14
Second: 10

到目前为止我有这个:

#include <stdio.h>
#include <string.h>

//"Saturday, July 8, 2017, 22:14:10"

int main(void) {
    char date[6][20];
    char *order[] = {"Month", "Day", "Year", "Hour", "Minute", "Second" };
    printf(" Example: Saturday, July 8, 2017, 22:14:10 \n Enter date seperated by commas in following format: \n");
    char text;
    scanf(" %s, &text");

    char* delims = " ,:";
    char* token = strtok(text,delims);
    char** label =  order;
    int r = 0;
    while (token){

        strcpy(date[r],token);
        printf("%-8s: %s\n ",*label,date[r]);
    token = strtok(NULL,delims);
    label++;
    r++;
    }
    return 0;
}

这是我运行代码时的输出

This is my output when I run the code

示例:2017 年 7 月 8 日星期六 22:14:10按以下格式输入以逗号分隔的日期:2012 年 8 月 1 日，星期一，21:12:9

Example: Saturday, July 8, 2017, 22:14:10 Enter date seperated by commas in following format: Monday, August 1, 2012, 21:12:9

进程完成，退出代码 -1073741819 (0xC0000005)

推荐答案

#include <stdio.h>
#include <string.h>

int main(void) {
    char *order[] = {"Day", "Month", "Date", "Year", "Hour", "Minute", "Second"};
    char text[]  = "Saturday, July 8, 2017, 22:14:10";

    char* delims = " ,:";
    char* token = strtok(text, delims);
    char** label = order;

    while(token)
    {
        printf("%-8s: %s\n", *label, token);
        token = strtok(NULL, delims);
        label++;
    }

    return 0;
}

输出:

Success #stdin #stdout 0s 4176KB
Day     : Saturday
Month   : July
Date    : 8
Year    : 2017
Hour    : 22
Minute  : 14
Second  : 10
