c++ - 使用 strtok 分割字符串

Question

 char *strings[30];
 char Policystr[4096] = "the|string|to|split"; 
 char delims[] = "|";
 int i = 0;

 strings[i] = strtok( Policystr, delims )
 while( strings[i] != NULL  ) 
{
        MessageBoxA(NULL,strings[i],"stringsComparison",MB_OK);
        strings[++i] = strtok( NULL, delims );          
}
for ( int j = 0; j < i; j++ ) 
 {
     MessageBoxA(NULL,strings[j],"strings",MB_OK);
 }

我是 C++ 的新手，如果我能够在第二个循环中打印相同的字符串，我会在第一个循环中获取所有字符串，我不知道，我没有得到

提前致谢

Answer 1

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

int main(void)
{
    char *strings[30];
    char Policystr[4096] = "the|string|to|split"; 
    char delims[] = "|";

    int i = 0;
    strings[i] = strtok( Policystr, delims );
    while( strings[i] != NULL  ) 
    {
        printf("%d '%s'\n", i, strings[i]);
        strings[++i] = strtok( NULL, delims );          
    }

    for ( int j = 0; j < i; j++ ) 
    {
        printf("%d '%s'\n", j, strings[j]);
    }
}

输出:

0 'the'
1 'string'
2 'to'
3 'split'
0 'the'
1 'string'
2 'to'
3 'split'
