如何在C ++中将变量存储在字符串数组中

Question

I am quite in to C++ and have a recent homework assignment which I need to store 1000 most common words into a string array. I was wondering how would I go about this. Here is my example code so far,

if(infile.good() && outfile.good())
    {
        //save 1000 common words to a string 

        for (int i=0; i<1000; i++) 
        {
            totalWordsIn1000MostCommon++; 
            break; 
        }

        while (infile.good()) 
        {
            string commonWords[1000];
            infile >> commonWords;
        }
    }

Thanks!

Answer 1

   #include <cstdio>
   #include <string>

   freopen(inputfileName,"r",stdin); 
   const int words = 1000;
   string myArr[words];
   for(int i=0;i<words;i++){
       string line;
       getline(cin,line);
       myArr[i] = line;      
   }

Answer 2

The for loop above does nothing at the beginning, just breaks at first iteration. It would be better if you'll read how to use loops in C++. Also take a look at the scopes of the variables in C++. In your case commonWords declared in while loop, so will be created each time and destroyed after each loop iteration. What you want is something like this:

int i = 0;
std::string commonWords[1000];
while (i < 1000 && infile.good()) {
    infile >> commonWords[i];
    ++i;
}

I'm living the remaining part for you to complete your homework.
