Write a program to read in a sequence of examination mark from a text file named as input.txt and produce the mean, and standard deviation of the marks. Your program should also produce a bar chart for each grade where the range of mark is given as below.
GradeMarks Range
A80-100
B70-79.9
C50-69.9
D40-49.9
F0-39.9
Output the result to another text file named as output.txt.
Here is what i have so far:
#include<fstream>
#include<iostream>
#include<string>
[Code].....
I also need to do a loop that scan the count array and check if the element is bigger than the previous one.
i have a question, i'm studyng the string library type and i have to write this program :
Code:
std::string word;
while (std::cin >> word) {
std::cout << word << std::endl;
}
why if my input is :
hi my name is ^Z
the output is :
hi
my
name
is
why the program doesn't fall out from the while loop ?
why my program does not recognize my sequence of end of file ?
My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.

write a program in c to read a sequence of N integers and print the number that appears the maximum number of times in the sequence.
View 1 Replies View RelatedI have been working on a program to read in a tab deliminated text file of xyz coordinates of atoms/particles and store the values in three seperate arrays. This is my code so far:
Code:
#include<stdio.h>
#include<stdlib.h>
void fileinput(FILE *ifp) {
int N, column, atom;
int c;
column = 1;
[Code]...
Supposedly this should assign the values in the text file to the cooresponding arrays but when I run the code on a simple test file all I get is:
Code:
$ ./input.o -i ./test.txt
Atom one coodinates x 0.000000, y 0.000000, and z 0.000000 Where test.txt is: Code: 1.0000 2.000 1.5
3.0000 5.000 1.4
4.0000 3.000 1.3
I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
known_vector frame1 151 65 0 frame2 151.000763 64.538582 0.563737
known_vector frame1 152 65 0 frame2 152.000702 64.542488 0.560822
known_vector frame1 153 65 0 frame2 153.000671 64.546150 0.558089
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000
0.000000 0.000000 0.000000 0.000000 0.000000 0.000000

The program needs to be able to read the middle names within the text file named Info2.txt
Simply adding the Mname or any related value where the other to name values doesn't do anything and only the 1st line appears on the output.
Don Jon111012
Jack Bo Todd151015
Jill Jo Jane161011
Bob Jack Chuck 131513
Da Fu111012
That is the correct way it appears in the text file. Also I know it's commented out, but that just to keep the program from crashing.

I am trying to get text file and read only first 100 lines of the text content using c/c++. how can i do it?
is it something like string line;
getline(stream,line);
??
The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Code:
readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}
[code]....
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.
I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?
I want to sort the lines based on the FIRST value.
Example text file contents:
values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324
Output: Text file containing
2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43
It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?
Basically I am to create a program that will read two saved text files; one is [2x4] ~ (matrixA.txt) and another is [4x2] ~ (matrixB.txt). The program is supposed to read both text files, multiply them, and generate an output that will be saved as ~ (matrixC.txt).
So here is my horrible attempt at it:
Code:
#include <stdio.h>
int main() {
FILE * fileA;
FILE * fileB;
FILE * fileC;

And these are the compile errors...

View 4 Replies View RelatedI'm a beginner at programming and I'm not sure how to read in information from a text file. What I want to do is take a text file which contains around 20 rows and 3 columns of numbers, and put these into an array which can then be used for performing calculations. How do I do this? Would I need to declare the size of the array beforehand? When accessing my file, do I include the full address?

How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.
Here I want to connect to website every 60 minutes and fetch only first 100 lines of the run.txt file as mentioned above. How can I do this using C++ and asynchronous winsock ???

I have been given an assignment that has to do with permutations. I am suppose to read a text file that contains the permutation rules and the text to be "permutated", and then output the rules and the new text into an output file.
So far, I've gotten this:
Code:
# include <stdio.h>
void printArray(FILE* file, char* array, int maxSize)
{
int i;
for (i = 0; i<maxSize; i++)
fprintf(file, "%c", *(array + i));
[Code] ....
Here is what the input file looks like:
Code:
0 1 2 3 4 5 6 7 8 9
4 5 6 0 9 7 8 1 2 3
Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
Here is what the output file is suppose to look like:
Code:
0 1 2 3 4 5 6 7 8 9
4 5 6 0 9 7 8 1 2 3
ratMnioodetem rpein al,ywa isvirsetu a t m;eod
buon r inaticipp,lerina s cpeis of icvies - Temho.

The first two lines are the permutation rules. Currently I have figured out how to read the file into an array and then print it back out into a text.
What I want to do is figure out how to read only the first two line of the input file and store that as a permutation rules, and then continue reading the rest of the input file and store that separately as the text to be "permutated". And then eventually figure out how to apply the permutation to the text.
