c++编写字符串分割函数之vector<string>的应用
#include<iostream>#include<string>
#include<vector>
using namespace std;
void _strtok(char *s,char *k,vector<string>& str){
char *ss=s;
char *p=strstr(ss,k);
while(p){
if(p-ss>0){
char *tt=new char;
memset(tt,0,p-ss+1);
strncpy(tt,ss,p-ss);
str.push_back(tt);
delete[] tt;
}
ss+=(p-ss)+strlen(k);
p=strstr(ss,k);
}
if(str.size()>0 && *ss!=0){
str.push_back(ss);
}
}
main(){
vector<string> str;
_strtok("q11sdfd11s","11",str);
cout<<str.size();
}其它例子：void main()
{
vector<string> str;
_strtok("*.exe|*.com","|",str);
cout<<"个数："<<str.size()<<"\n";
int i;
for(i=0;i<str.size();i++) cout<<str<<"\n";
} 我来支持一下
