I am trying to read numbers stored in a txt file to populate an integer array. The problem is that the numbers read from a file have to be treated as strings and then I am not able to put them in an integer array.
I tried the stoi function to convert the string in 'box' into an integer but I am getting an error.
Code:
#include <iostream>
#include <stdlib.h>
#include <fstream>
#include <string>
using namespace std;
int main() {
int amount=10;
int k[amount];

I am working on a project for school that has us read in a text file that contains 8 lines of SSN and grades. I am not sure how to go about reading in the lines and differentiate between the SSN and grades in the calculations.

My code is working all except one part I'm just completely stuck on and it's probably something simple. There are 14 numbers in the file. The way I have the code now it will tell me there are 14 which is correct but it displays my low number as 0 and it should be 6. If I change if(infile) to if(infile >> num) it will read the correct low number as 6 except now it says there's only 13 numbers and it's not reading the first number in the file which is 23 so it skews the whole program.

I would like to program a simple finite element solver in c++ (I'm a relatively new programmer by the way). This is the issue, I have a text file with all the information of the model arranged in matrices; an input file would look something like this:
*nodes
1 0 0 0
2 10 15 0
3 17 2 0
4 -4 -1 0
*elements
1 1 2
2 2 3
3 3 4
*material
1 2.0e5 0.30 7.85e-9
2 7.0e4 0.21 2.11e-9
*loads
1 0 0 0
4 0 0 0
So, i want to read this text file and get each of the "*" matrices in its own array. The size of the matrices is not know.
I am trying to read lines from a .txt file like this:

This is the second line.

The output I want is:
This is the first line.
This is the second line.
However, all I am getting is:

Reading in a maze into a 2D array. The first two reads will give me the dimension of the maze(ex. m x n maze). So in order to create the 2D array i need the first two reads. Then after it is created it will read the rest of the data which are 1s and 0s. I have to create a program that will solve the maze but i cant test my movement code if i cant read in the data first. the entire program compiles but to test if i read the file i have a function to print it. But it says "There are: 0 rows and 0 columns " so it didn't read anything since rCount and cCount are initialized to 0. and basically the maze has nothing in it.

read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2
139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
while(getline(input, line)) {
istringstream ss(line);
ss >> match_code >> team1;
string temp;
while(ss >> temp) {
[Code] .....
In that missing part, I need to get the second word of team name if there is one; and the three odds that are odd1 odd0 and odd2.
Each line of the text file has first name, last name, and a salary. Something along the lines of this:
john doe 4000
bob miller 9000
I want my program to take the first name, last name, and salary of each line and assign them to strings. I have tried this so far:
while (inFile){
inFile >> firstName;
inFile >> lastName;
inFile >> grossPay;
cout << firstName << " " << lastName << " " << grossPay << endl;
}
When it outputs the names and the salary, the last line of the text file gets output twice by the program.
My project includes opening and reading a text file ("customers.txt"). This is my text file:

I am working on my final project for my intro to c++. Its a simple program where you buy a car, choose parts for it, see the price of it in total, buying option, and to view past records.
So my problem lies with displaying the records. For some reason(doesn't many how many records there are) the very last record displays again without the "Model" part, but displays the rest of them fine. In other words, there are 2 problems, the last record is displayed twice, 2nd that added record displayed is missing the "model"(this problem doesn't matter really if you can solve the first problem, but would still like to know why it does that).
I tried debugging it and I believe the problem lies with the --------while(fName.good()). It just decides to repeat it again even though in the text file, it does not have that extra record.

I think it comes from having to align the data in the output file. How to start this is to use a function to read in all the characters using a while loop. Then read in all the digits in a separate function. When it comes to outputting the data in the correct format I'm lost, so for now if I could figure out the functions that would be awesome. A final note we have not gotten to using strings so the I'm trying to use getc, fgetc, and ungetc.
Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a students first name, then one space, then the students last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be the same as the data in the input file except that there will be one additional number at the end of each line: the average of the students ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings. Use formatting statements to make the layout clean and easy to read.
I need to open a file that has multiple lines that look something like this, " black box 100.01 33.5 78.93". What this shows is the coordinates of the black box. Lines will have different objects with different coordinates. I need to create a loop that will read this file and tell me when a black box is found by displaying a message. I don't need to know how to create this file. I don't need to display the entire file but rather have it search for black boxes.
