Im not sure how to use strtok to separate tokens


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

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

I have this so far:

#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;
}

This is my output when I run the code

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

Process finished with exit code -1073741819 (0xC0000005)

What Am I doing wrong. Please help!


Solution

  • #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;
    }
    

    Output:

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