//将字符串按空格分割
#include<bits/stdc++.h>
using namespace std;
int main(){
string str;
// getline(std::cin, str);
str = " 123 abcd 789 0";
vector<string> lis;
string::iterator myBegin = str.begin();
string::iterator myEnd = str.begin();
//按空格分割
while(1){
myEnd = find(myBegin, str.end(), ' ');
if(myBegin >= str.end()){ //退出条件
break;
}
if(myEnd != myBegin) //若要忽略多余的空格就加上这行:非空格时才存
lis.push_back(string(myBegin, myEnd));
myBegin = myEnd+1;
}
//按空格分割
for(int i = 0; i < lis.size(); i++){
cout<<lis[i]<<endl;
}
return 0;
}思路:while循环,循环内find找指定的字符,找到后就存入vector
c++ string 切割字符串, 按空格分割
