C++ break和continue

#include <iostream>
using namespace std;
const int my_size = 80;
int main(){
    char line[my_size];
    int spaces = 0; 

    cout << "Enter a line of text:\n";
    cin.get(line, my_size);
    cout << "Complete line:\n" << line << endl;
    for (int i = 0; line[i] != "\0"; i++)
    {
        cout << line[i];    // display character
        if (line[i] == ".") // quit if it"s a period
            break;
        if (line[i] != " ") // skip rest of loop
            continue;
        spaces++;
    }
    cout << "\n" << spaces << " spaces\n";
    return 0;
}
