Little help with fstream outFile
Hey all,
Have a slight problem I can't seem to figure out. First, I am a beginner in C++ and this is an assignment due 4/2/2010. Forgive me if the solution is simple...it's just evading me at the moment.
OK, my problem is in the FSTREAM portion of my code (near the bottom). I am trying to read 5 numbers from an inFile. I got this working, however, the 2nd part is writing the stored numbers from the inFile into a SECOND file....which I named "outFile_Reverse.open" is my dilemma.
It does not read the correct numbers. I suspect it's reading numbers from the portion of the code titled "ARRAY OF INT" because I pasted the "for loop" into the FSTREAM logic. It displays "5 4 3 2 1" So, how can I make inFile_1 read the stored numbers_1 text file and display them in reversed order?
Here is my code:
Code:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
int number[5];
int input;
int counter;
string words[6];
const string end = "end of array";
cout <<"\n=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-ARRAY OF INT-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=" <<endl;
cout <<"\n\nThis portion of the program will ask you to type in 5 numbers." <<endl;
cout <<"It will then display them back to you in reverse order." <<endl;
cout <<"\nPlease enter 5 positive numbers with a space between each: ";
for (counter = 0; counter < 5; counter++)
{
cin >> number[counter];
}
cout <<endl;
cout <<"\nThe numbers in reverse order are ===> ";
for (counter = 4; counter >= 0; counter--)
{
cout <<number[counter] << " ";
}
cout <<"\n\n\n\n=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-ARRAY OF STRING=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=" <<endl;
cout <<"\n\nThis portion of the program will ask you to type in 5 words." <<endl;
cout <<"It will then use a do while loop and display the 1st and 3rd letter of each" <<endl;
cout <<"word using the substring function." <<endl;
cout <<"\nPlease enter 5 words:\n"<<endl;
for (counter = 0; counter < 5; counter++)
{
cin >> words[counter];
}
counter = 0;
cout <<"\n\nThe 1st and 3rd letter of each word you entered are:\n" <<endl;
do
{
if(words[counter].size() >= 3)
{
cout << words[counter][0] << words[counter][2] << "\n\n";
}
else
{
cout <<"\n\n\tUH-OH ===> One or more words you entered have less than 3 characters." <<endl;
cout <<"\tOnly words containing 3 OR MORE characters will display a result.)" <<endl;
}
counter++;
}
while (counter < 5);
cout <<"\n\n\n=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-FSTREAM=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=" <<endl;
cout <<"\nThis portion of the program will:\n\n" <<endl;
cout <<"1. Read 5 numbers FROM a text file" <<endl;
cout <<"2. Write the numbers in reverse order to a SECOND file" <<endl;
cout <<"3. Read 5 words in from a THIRD file" <<endl;
cout <<"4. Display results of words to the CONSOLE\n\n" <<endl;
ifstream inFile_1; // File we are reading the numbers from
ifstream inFile_2; // File we are reading the words from
ofstream outFile_Reverse; // File to use for output
string numbers_1 ; // Name of number txt file
string words_1; // Name of words txt fileLi
int num1, num2, num3, num4, num5; // Declaring variables to read numbers from stored file
string w1, w2, w3, w4 ,w5; // Declaring variables to read words from stored file
inFile_1.open("numbers_1.txt"); // File stream variable to open numbers_1.txt file to read
inFile_2.open("words_1.txt"); // File stream varibale to open words_1.txt file to read
outFile_Reverse.open("outFile_Reverse.txt"); // File stream variable to display reversed numbers into this outFile.
/***********************************************************************************************
outData file to display words_1 is not needed; displaying directly to console from inFile_2.
***********************************************************************************************/
inFile_1 >> numbers_1;
outFile_Reverse << numbers_1;
for (counter = 4; counter >= 0; counter--)
{
cout <<number[counter] << " ";
}
// inFile_2 >> words;
// cout <<"The words stored in the words.txt file are: "<<words<<;
inFile_1.close(); // Closes numbers_1.txt file
inFile_2.close(); // Closes words_1.txt file
outFile_Reverse.close(); // Closes outfile
cin.get();
cin.get();
return 0;
}
