c++ 根据字符串之间的特定的符号,分割出想提取的子字符串，如33°25′18〃分段取出该串中的数据

Answer 1

你看看这个例子吧

// crt_strtok.c
// compile with: /W3
// In this program, a loop uses strtok
// to print all the tokens (separated by commas
// or blanks) in the string named "string".
//
#include <string.h>
#include <stdio.h>

char string[] = "A string\tof ,,tokens\nand some more tokens";
char seps[] = " ,\t\n";
char *token;

int main( void )
{
printf( "Tokens:\n" );

// Establish string and get the first token:
token = strtok( string, seps ); // C4996
// Note: strtok is deprecated; consider using strtok_s instead
while( token != NULL )
{
// While there are tokens in "string"
printf( " %s\n", token );

// Get next token:
token = strtok( NULL, seps ); // C4996
}
}
