C + + divides the string into two dimensional word groups, 2 kinds of segmentation methods __c++

This experiment is to read a string in the INI file, the string is the form of a two-dimensional array. Method One

First I use the strtok_s;
Note:

The use of 1.strtok_s
Function prototypes:char *strtok_s (char *strtoken, const char *strdelimit, char **buf);
This function guarantees security by storing the remaining strings in the BUF variable rather than in the static variable.
The use of 2.strtok
Function Prototypes: char * strtok (char str, const char delimiters);
Parameters: str, string to be segmented (c-string); delimiters, delimiter string.
3. Difference:
strtok_s support Multithreading , Strtok can only be a single thread .

The files in INI are:

[Matrix]
data = 0, 0.3, 0.35, 0.40, 0.45, 0.5, 0.55, 0.60@ 20, 0.378, 0.421, 0.46, 0.496, 0.529, 0.559, 0.585@ 30, 0.261, 0.294, 0. 326, 0.357, 0.388, 0.419, 0.448@ 40, 0.183, 0.208, 0.232, 0.258, 0.285, 0.311, 0.339@ 45, 0.155, 0.177, 0.198, 0.22, 0.245 , 0.272, 0.295@ 50, 0.135, 0.154, 0.172, 0.192, 0.214, 0.236, 0.261@ 60, 0.106, 0.121, 0.136, 0.152, 0.166, 0.189, 0.210@ 70, 0.086, 0.098, 0.111, 0.123, 0.316, 0.154, 0.172@ 80, 0.074, 0.085, 0.096, 0.106, 0.117, 0.133, 0.149@

The code to run under VS2013 is:

#include <windows.h>
#include <string.h>
#incldue <iostream.h>

    Char data[500];
    Char ii1[15][100] = {0};
    Double C[colum_data][row_data] = {0};//row_data, Colum_data is its own defined
    int icount = 0,jcount = 0;
    char *ptr1;
    Char *ptr


    :: Getprivateprofilestringa ("Matrix", "Data", "" ", data, sizeof (data)-1," INI storage location ");
    PTR = strtok_s (data, "@", &p);     strtok_s can generate dynamic link libraries
    while (PTR!= NULL)
    {
        strcpy_s (Ii1[icount], ptr);
        Division The data again
        ptr1 = strtok_s (PTR, ",", &P1);     
        while (ptr1!= NULL)
        {
            strcpy_s (ii1[jcount), ptr1);
            C[icount][jcount] = atof (Ii1[jcount]);
            jcount++;
            PTR1 = strtok_s (NULL, ",", &P1);
            if (Jcount = = row_data) jcount = 0;
        }
        icount++;
        ptr = strtok_s (NULL, "@", &p);
    }

Method Two

Because strtok_s cannot operate on VC6.0, VC6.0 only supports strtok, while Strtok only supports single-threaded . Therefore, we have to read it in a different way.

[Matrix]
data = 0, 0.3, 0.35, 0.40, 0.45, 0.5, 0.55, 0.60@ 20, 0.378, 0.421, 0.46, 0.496, 0.529, 0.559, 0.585@ 30, 0.261, 0.294, 0. 326, 0.357, 0.388, 0.419, 0.448@ 40, 0.183, 0.208, 0.232, 0.258, 0.285, 0.311, 0.339@ 45, 0.155, 0.177, 0.198, 0.22, 0.245 , 0.272, 0.295@ 50, 0.135, 0.154, 0.172, 0.192, 0.214, 0.236, 0.261@ 60, 0.106, 0.121, 0.136, 0.152, 0.166, 0.189, 0.210@ 70, 0.086, 0.098, 0.111, 0.123, 0.316, 0.154, 0.172@ 80, 0.074, 0.085, 0.096, 0.106, 0.117, 0.133, 0.149@

Solving method

#include <windows.h>
#include <string.h>
#incldue <iostream.h>

    Char data[500];
    Char iii[15][100] = {0};
    Double C[colum_m][row_m] = {0};
    int icount = 0,jcount = 0;
    char *ptr1;
    Char delims[] = "@";


    Load the M_c from Agd.ini
    :: Getprivateprofilestringa ("Matrix", "Data", "" ", data, sizeof (data)-1," INI stored directory ");
    char* buf = data;
    char* result = NULL;
    while (result = Strstr (buf,delims))!=null)
    {
        result_c[0] = ';
        PTR1 = Strtok (buf, ",");
        while (ptr1!= NULL)
        {
            strcpy (iii[icount), ptr1);
            C[icount][jcount] = atof (Iii[icount]);
            jcount++;
            PTR1 = Strtok (NULL, ",");
            if (Jcount = = row_m) jcount = 0;
        }
        icount++;
        BUF = result + strlen (delims);
    }

This method has a good effect on solving the VC6.0 of strtok_s. Thus recorded in this.
