1+2!+3!+........+12!
修正一楼的
#include <iostream>
using namespace std;
void main() {
int n = 12, s = 0, x = 1;
for(int i = 1; i <= n; i++)
s += x *= i;
cout << " s = "<< s << endl;
cin.ignore();
}
s = 522956313
Press any key to continue
main() {
int n = 12, s = 0, x = 1;
for(int i = 1; i <= n; i++)
s += x *= i;
cout<<" s = "<<s<<endl;
}
