Customer Decipher program c++ Trouble reading in - c++

Question

So I have a custom decipher program that reads in an input file and deciphers it based on the keys that are input.
Text file:
23
11
Java 2 linux 3 fear 0 pool 2 do 0 red 1 lock. 1 I 0 random 2 computers, 0 not 0 the 0 open 2 car! 2 C, 0 lack 0 of 0 dog 1 green 2 C++ 0 bottle 2 wrong, 2 them. 0
5 1 10 21 9 6 21 11 13 16 20
This file is represented as:
[Number of Words]
[Number of Keys]
[Word] [Jump] [Word] [Jump] ... [Word] [Jump]
[Key] [Key] ... [Key]
I have managed for the program to read in the number of keys and amount of words, however I have having trouble reading in the words and the numbers next to them as well as the last numbers and registering those as keys. This is what I have so far:
#include <iostream>
#include <fstream>
using namespace std;
struct pieces {
char word;
int jump;
} ;
// Main Function
int main ()
{
// declare variables
int keyCount = 1;
int wordCount = 8;
int wordAmount[8];
int keyAmount[8];
pieces cipher[5];
char decoded[20][20];
char filename[10];
int keys[keyCount];
char tArray[20][20];
ifstream inData;
//prompt user for input file
cout << " Enter file name: ";
cin >> filename;
inData.open(filename);
if(inData.is_open());
{
// read list of names into array
for ( int i = 0; i < keyCount; ++i){
inData >> wordAmount[i] >> keyAmount[i];
for(int j = 0; j < wordCount; j++){
inData >> cipher[j].word >> cipher[j].jump;
}
}
cout << " Key Count: " << keyCount << "\n";
// print out
for ( int i = 0; i < keyCount; ++i){
cout << " KeyAmount: ";
cout << keyAmount[i] << "\n";
cout << " WordAmount: ";
cout << wordAmount[i] << "\n";
for(int j = 0; j < wordCount; j++){
cout << cipher[j].word << " " << cipher[j].jump;
}
}
}
inData.close();
return 0;
}
I did try putting the char word as an array but then I got a segmentation file. Any advice would be appreciated!

IMHO, your project would be simpler if you used std::string and overloaded the formatted input operator >>:
struct Word_Jump
{
std::string word; // Using std::string because it has space for more than one character.
int jump;
friend std::istream& operator>>(std::istream& input, Word_Jump& wj);
};
std::istream&
operator>>(std::istream& input, Word_Jump& wj)
{
input >> wj.word;
input >> jump;
return input;
}
Your input could look something like this:
std::vector<Word_Jump> database;
for (unsigned int i = 0; i < number_of_words; ++i)
{
Word_Jump wj;
my_data_file >> wj;
database.push_back(wj);
}
Similarly, you input for reading keys:
std::vector<int> key_database;
for (unsigned int j = 0; j < number_of_keys; ++j)
{
int k = 0;
my_data_file >> k;
key_database.push_back(k);
}
So the above are two possible methods for reading in the word & jump pairs and also the keys.
