c++ 字符串和数字拼接
方法一:
#include <iostream>
#include <string>
#include <sstream>
using
namespace
std;
int
main()
{
int
a = 2;
string b =
"abc"
;
stringstream ss;
ss << a << b;
cout << ss.str() << endl;
return
0;
}
方法二:
#include <iostream>
using namespace std;
int main()
{
int a = 6;
char b[10];
sprintf_s(b, "abc%d", a);
cout << b << endl;
system("pause");
return 0;
}
