【求助】istringstream如何在输入一次后获取剩余的流字符串

[thecorr]

istringsream input("-3aaa");
int temp;
input >> temp;

如上代码后，如何获取input里剩余的“aaaa”。

[mujiok2003]

istringsream input("-3aaa");
int temp;
std::string s;
input >> temp >> s;

[图灵狗]

#include <string>
#include <sstream>
#include <iostream>
using namespace std;

int main(int argc, char* argv[])
{
	istringstream input("-3aaa");
	int temp;
	string str;

	input >> temp;
	input >> str;

	cout << temp << endl;
	cout << str << endl;

	return 0;
}

仅供参考

#include <stdio.h>
char s[]="123 ab 4";
char *p;
int v,n,k;
void main() {
    p=s;
    while (1) {
        k=sscanf(p,"%d%n",&v,&n);
        printf("k,v,n=%d,%d,%d\n",k,v,n);
        if (1==k) {
            p+=n;
        } else if (0==k) {
            printf("skip char[%c]\n",p[0]);
            p++;
        } else {//EOF==k
            break;
        }
    }
    printf("End.\n");
}
//k,v,n=1,123,3
//k,v,n=0,123,3
//skip char[ ]
//k,v,n=0,123,3
//skip char[a]
//k,v,n=0,123,3
//skip char[b]
//k,v,n=1,4,2
//k,v,n=-1,4,2
//End.
