Suppose you just recieved a shipment of twelve televisions. Two of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work? Suppose you just recieved a shipment of twelve televisions. Two of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work? Solution.

1. Tffff
The program needs to be in C++ and part 1 of the assignment is already done. The only
difference is that the appropriate text files that will be used for this program... some of them are
large txt files (chapter of a book for example to almost a complete book).
Part 2 is the Question!!!
The code for part one is shown below:
#include // required header files
#include
#include
using namespace std;
int main() // driver method
{
string myArray[100]; // array to store the data
string filename; //required initialisations
ifstream file;
int count = 0;
cout << "Please enter the input file name: "; // prompt for the user to enter the filename
cin >> filename;
filename = filename+".txt";
file.open( filename.c_str() ); // opening the filename
if(file.is_open()) // checking for the opening of the file
{
while ( !file.eof() ){
count++; // incrementing the count for the lines
for(int x = 0; x < count; x++){
file >> myArray[x]; // saving the data to the array
cout << "The Array Data is : " << myArray[x] << endl; // printing the output to console
}
}
file.close(); // closing the file
} else {
cout << "Error Opening the File!!" << endl; // catching the exception

2. }
cout << " The total Words in the file are : " << count << endl; // getting the count from the
lines
return 0;
}
OUTPUT :
Please enter the input file name: input
The Array Data is : John
The Array Data is : Carter
The Array Data is : Harry
The Array Data is : Mornie
The Array Data is : Michael
The Array Data is : Mary
The Array Data is : Newton
The total Words in the file are : 7
Now from this code, how can we adjust it so part 2 from the assignment fits in.
Solution
Please follow the code and comments for description :
CODE :
#include // required header files
#include
#include
#include
using namespace std;
int main() // driver method
{
string myArray[100]; // array to store the data
string filename, line; //required initialisations
ifstream file;
int count = 0, index = 0, occurrence = 0, foundOcc = 0;
cout << "Please enter the input file name: "; // prompt for the user to enter the filename
cin >> filename;
filename = filename+".txt";

3. file.open( filename.c_str() ); // opening the filename
if(file.is_open()) // checking for the opening of the file
{
while ( !file.eof() ){
count++; // incrementing the count for the lines
for(int x = count; x <= count; x++){
index = index + 1;
file >> myArray[x]; // saving the data to the array
cout << "The Data is : " << myArray[x] << " found at index value : " << index <<
endl; // printing the output to console
}
}
file.close(); // closing the file
} else {
cout << "Error Opening the File!!" << endl; // catching the exception
}
for (int i = 1; i <= count; i++) {
// checking to the data in the array if it was used before
int found = 0;
for (int j = 0; j < i; j++) {
if (myArray[i] == myArray[j]) {
found++;
}
}
// continuing if it's the first occurrence
if (found == 0) {
// starting the count with initial value
occurrence = 1;
// checking the data in the array for other occurances
for (int j = i + 1; j < 8; j++) {
if (myArray[i] == myArray[j]) {
occurrence++;
}
}
cout << " Occurrences of the Word " << myArray[i] << " is : "; // printing the number
of occurances

4. cout << myArray[i] << " : " << occurrence << endl; // printing the data of the array
float percent = (float)(occurrence*100)/count; // calculating the percent of the occurances
cout << "Percentage of Occurrence of the Word " << myArray[i] << " is : " << percent
<< "%" << endl; // printing the data and the percent of occurrence
if(occurrence > 1){
foundOcc++; // calculating the total occurrences in the file
}
}
}
cout << " Number of Occurrences Found in the data read are : " << foundOcc << endl; //
printing the results
cout << " The total Words in the file are : " << count << endl; // getting the count from the
lines
return 0;
