about using input file (File I/O stream)
I got a problem about File I/O stream. I have created a text file which is called input.txt which contains 80 characters in each line. The follwoing codes I did typed, but, I don't know how to use the input file to calculate the numbers of upper cases and the numbers of lines. Please help me!

#include <iostream>
#include <string>
using namespace std;
#include <fstream>
int main()
        ifstream fin1 ("input.txt");
        if (!fin1)
                cout << "Cannot open infile: input.txt\n";
                cout << "Infile: input.txt opened.\n";
                cout << "Number of spaces: ";
                char ch[1000];
                int numchar = strlen(ch);
                int count1 = 0;
                for (int i=0;i<numchar;i++)
                                if (ch[i] == ' ')
                cout << count1;
                cout << endl;
                cout << "Number of upper cases: ";
                int sum1 = 0;
                for (int i=0; i<numchar;i++)
                        if (isupper(*ch))
                cout << sum1;
                cout << endl;
                cout << "Number of lines: ";
                cout << endl;
        return 0;

Thanks a lot!!!
