第十六周--阅读程序

#include <iostream>
#include <cstdlib>
#include <fstream> // (1)
using namespace std;
int main()
{
fstream file;
file.open("abc.txt", ios::in); // (2)
if(!file)
{
cout<<"abc.txt can’t open."<<endl;
exit(1);
}
char ch;
int i=0;
while(file.get(ch)) // (3)
{
++i; // (4)
}
cout<<"Character: "<<i<<endl;
file.close();// (5)
return 0;
}
