C :: Fscanf Data To Arrays

Apr 17, 2014

I am a very fresh c programme user, in fscanf data to arrays. Somehow it just doesn't gets recorded, wonder what is wrong with my code? When I printf the array it always ends up with random numbers.

Here is my code:

#include <stdio.h>#define SIZE 2
#define count 2
int main()
{
[code]....

and the file i am trying to read from :

Code:
1, 2, 3, 4
5, 6, 7, 8
8, 9, 10, 11

I am trying to scan a list of 3 by 4 numbers and the 4 numbers of each column to the 4 different arrays, so if I read from the data above, i get an array with numbers 1,5,8; another with 2,6,9 and so on. Is it how its done in my code?

C++ :: Using Arrays As Sources Of Data For Arrays In A Structure?

Feb 6, 2014

I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.

I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.

How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)

Code:

int _tmain(int argc, _TCHAR* argv[]) {
int comm = 10;
int targ = 5;
int death;
struct AI_WORDS

[Code]....

C :: How To Count Lines In Dat File Using Fscanf

Sep 15, 2013

I need a way to count lines in a .dat file using fscanf. I must use a regex to check that the characters in the file are alphanumeric. In essence I need to count the ' ' character. I know fscanf ignores this character. I need to exit if it detects anything other than alphanumeric with the digit that is "problem" along with the line number. My .dat file is:

Code:
howard jim dave
joe
(
Maggie My fileCheck.c is: Code: #include "main.h"
int fileCheck(FILE *fp)
{
int ret_val;
int line_count = 0;
char file[BUFF];

[Code]...

The output I am getting is:

Code:
file opened Digit: ( is not an alphanumeric character on line: 5 Program will exit! File closed As you can see, the character "(" is not on the 5th line but the 3rd. It is the 5th "string."

I also wanted to show the regex I am using.

Code:
#define to_find "^[a-zA-Z0-9]+$"

How this can be accomplished?

C/C++ :: Use Fscanf To Obtain A Set Of 14 Or So Strings Per Line?

Feb 25, 2012

I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:

FILE *d;
d=fopen("t.dat","rb");
where a, n are all strings.
fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);

A sample of the Input file looks like this:
USB270.15385-29.63146 270.153847 -29.631455 2.966699e+03 -9.99 1.300391e+03 -9.99 -9.99 A-A-- 6.787463e+01 -9.99 1.555773e+02 -9.99 -9.99 10100 | ----- ------ ------ ------ | 0.373 13.554 12.928 12.670 AAA | ----- -------- - -------- - -------- - -------- - | --- ---------- - ---------- - --------- - --------- - --------- - ---------- -

C :: Fscanf - Segmentation Fault For Larger Project

Apr 19, 2013

I added this snippet of code to a larger project I use to read some numbers in from a file, but for some reason I'm getting a segmentation fault.

Code:
printf("starting main
");
FILE *cutoffs;
double cut1=0, cut2=0, cut3=0;
printf("trying to open file

The cutoffs.in file looks something like

Code: 3.475 3.875 4.025

I ran the gdb debugger, so I know it is occurring at that fscanf; however, it doesn't give any other details (to be honest I don't have much experience with debuggers :x) ..The values are being put into an array. Before I just had numbers initialized in the array by hand, but need to have 20 different runs of this code with different numbers each time...

C++ :: Fscanf And Verifying Correct Input Length

Jan 24, 2012

I am trying to make a program that will read in input in the following format:

| ...text... || ...more text... || ...still more text...|

i.e. every bit of "text" that gets read in is bracketed on either side by the "|" character.

The buffer that i read them into can be of a maximum length of 101 (100 characters plus a terminating null character); this is how I am currently reading in the input:

char readString [100 + 1];
while ( fscanf(infile, "|%1000[^|]|", readString) ){
/*... manipulate readString ...*/
}

How might I design this program so that, should any of the text appearing between the "|" characters exceed 100 in length, it exits and returns a warning?

C :: Storing PPM Data Into Arrays

Mar 29, 2014

I am doing this program where I analyze colors in a ppm file. Now I am having a hard time storing the data into arrays in this order...

P3
600 339
255
44 5 8
44 5 8
43 4 7
42 3 6
42 3 4
44 5 6
...

So far i tried using fscanf()

Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <stdbool.h>

#define DEBUG true
#define CHECK true

[Code] ....

I then realized that the order that the second method gave me will make it very hard for me to calculate the RGBs. Because they will be calculated like wise..

P3
600 339
255
44 5 8 = sum
44 5 8 = sum
43 4 7 = sum
42 3 6 = sum

42 3 4 = sum
44 5 6 = sum
...

but that isn't the issue right now..

C/C++ :: Arrays And Enumerated Data Types

Feb 18, 2014

I am doing a programming assignment. This program asks you to collect statistics on precipitation and temperatures from the four quarters of a year and print the calculated results. It is an exercise in using enumerated types and arrays. The measurements are entered at the end of every quarter.

Major variables (there are other variables) in the program:
Variable called: month of type Summary_Month (the enumerated type)
Arrays of integers called: low_temp, high_temp, precip
Array of doubles called: avg_temp

You will ask the user to enter the precipitation, low temperature and high temperature for each quarter. As you gather this data, you will calculate the average temperature (using avg_temp) for each quarter by averaging the low and high temperature for that quarter.

After you gather the information you will calculate and output : Total Precipitation for Year, Average Quarterly Precipitation, Average Quarterly Temperature, Highest Temperature for any quarter, Lowest Temperature for any quarter.

I am not getting the right output for average precipitation and temperature and I am not sure how to determine the highest and lowest temperature.

# include <iostream>
# include <iomanip>
using namespace std;
enum Quarters { March, June, September, December};
int main() {
const int NUM_QUARTERS = 4;

C++ :: Read N Data Items Into Two Arrays (X And Y) Of Size 20

Apr 1, 2013

Trying to do a homework assignment for a class and how to read a file into an array. I've looked in our book and on several other forums and cant seem to find any examples of this. Below is the assignment I'm working on. I have a shell of the program that I can get to run, but getting a .txt file to read into an array is something I cant seem to figure out how to do.

Write a program to read N data items into two arrays, X and Y, of size 20. Store the product of the corresponding pairs of elements of X and Y in a third array Z, also of size 20. Print a three column table that displays the arrays X, Y, and Z. Then compute and print the square root of the sum of the items in array Z. Compute and print the average of the values in array Z and print all values above the average of array Z. Determine the smallest value in each array using only one function.

Use the two data files named DATAX.TXT and DATAY.TXT.

You must use functions for the reading of the data, computing the average, printing the three column table and printing the values above average.

C++ :: Output Data From Two Sorted Arrays Into One File?

I am trying to output data from two sorted arrays into one file(which should also be sorted). The program works for most of the data, but after it reaches a certain record begins outputting garbage. I'm sure part of the problem is that I don't know what to include in my while loop that outputs to the file.

I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.

Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:

"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"

C++ :: Outputting Data From File Into Structs And Arrays Of Structs

Apr 15, 2013

I am having a lot of trouble being able to get data from a file and input it into given structs and arrays of structs and then outputting the file. We are given a file that contains 96 lines and looks like this:

Arzin, Neil
2.3 6.0 5.0 6.7 7.8 5.6 8.9 7.6
Babbage, Charles
2.3 5.6 6.5 7.6 8.7 7.8 5.4 4.5

This file continues for 24 different people and then repeats with different scores (the second line).
The first number, in this case is 2.3 for both people is a difficulty rating. The next 6 numbers are scores.

We are given this data in order to set up our structs and arrays and my code:

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
#include <cmath>
using namespace std;
int main () {
ifstream inFile;
inFile.open("C://diveData.txt);
