C :: Possible To Mix Characters And Integer Values In A Text Document
Jul 23, 2013
I was just wondering whether or not it is possible to "mix" characters and integer values in a text document that is to be read by C.
I am to read and use values for length around the hip, neck and such, however, most of the tutoring examples I am finding online seem to strictly deal with either integers or characters alone.
Basically my text file looks a bit like:
Abdominal length: 90.000
Neck length: 26.500
and so on
So, before I move further into this subject, is it possible at all to isolate and use only the double values or will I have to format my text file differently?

I'm trying to passing values from a text file to an array. The values in txt file is;
0 2 3 5
1 2 5
0 1 3 6
1 3 5
I need to store these values in an array like that
Code:
int array[?][?]={{0,2,3,5},{1,2,5},{0,1,3,6},{1,3,5}};

make a text file full of vocabulary wordsRead in that file and allow the user to specify the .doc file (should be simple)Go through the .doc file and highlight all the words that appear in the .txt file green.Open the .doc after the process is complete.
After I accomplish that, I can try to make more tweaks by maybe using a database instead for my vocabulary words and implementing error checking to be sure there are no duplicate entries, specify a different color for certain words instead of using just one color, etc. First and foremost, however, I want to know if the bare basics would be possible. I'm new to C++, but I have about 2yrs of Java under my belt, so I should be able to catch on relatively fast.

so the data file is a .txt that is going to be pre-written like this:
numbers:
562
444223.123321 312233.31222 3232323.31122
332231.323223 333232.32323 3232322.32233
am i reading the txt correctly? why are the numbers so weird when i "cout" to check?
#include <iostream>
#include <cmath>
#include <cstdlib>
#include <fstream>
#include <sstream>
#include <ctime>
#include <stdlib.h>
using namespace std;
int main() {
double mb1; //mass body 1

I'm trying to make a program that reads data from a text document and allows me to modify it. I am stuck with the display() function. I can get the printf statement to display all my array values except the char AD value. When I include flight[i].AD it causes the program to crash. When I run the program to only display the AD variable I get a bunch of weird symbols. I'm not sure where the program is going wrong because it seems to be storing values properly except for the AD variable.
#include <fstream>
using namespace std;
//named constants
const int MAX=100; //maximum flights
const int SIZE=20; //maximum characters
//struct definition
struct FlightType
{
char name[SIZE];

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

You should implement the following function:
int is_phone_number(char* string)
This function will take in a string and return 1 if it looks like a phone number 0 otherwise. A phone number takes the form (xxx)-xxx-xxxx where the xs are digits 0-9. So for example (123)-456-7890 is a valid phone number while 123 456-7890 is not.
You should also write a main function that parses a text document and prints out all of the phone numbers found. Hint, look up the strtok function.
Sample input:
Please call me at (123)-456-789 sometime tonight.
Sample output:
Phone number : (123)-456-7890

I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2

I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?

Q1. Recursive function that receives an integer x and prints the alternating alphabetic characters.
Write a main function to test the function;
ENTER NUMBER : 4
A C E G
Q2. Define a void function that finds the smallest value in the array and number of its occurrences. Also, it finds the largest value in the array and number of its occurrences.
ENTER 4 NUMBERS:
1 12 5 41 41
THE BIGGEST IS 41 AND IT OCCURS 2 TIME
THE SMALLEST IS 1 AND IT OCCURS 1 TIME

i am having trouble finding a way to detect integers from an external text file. i currently have this code:
while(inputfile.get(wc))
{
char character = inputfile.get(wc);
if (character + 1 != NULL)
{
cout << character << endl;
}
}
this does not work as if (character + 1 != NULL) comes up with errors.
is there a way to detect ints?

I'm supposed to write a program to read a text file and display the following:
a) alphabetic letters //finished with
b) digits // finished with
c) other characters that are not alphabetic letters and not digits //finished with
d) total characters read
The bold part above confused me, by total characters, does it mean the alphabetic letters + other characters? how would I put that in my code?
Code:
#include <stdio.h>
int main (void)
{
int curCh;
int countCh = 0;

I'm challenged to write a code for the following:
write a text up to 1000 characters, and get it back. the end of the text is detected though EOF on a new line or reaching 1000 characters.(EOF=ctr-Z on a new line)
I mainly have problem how to bring the EOF work probably. it doesn't react when I press ctrl-z directly?
Code:
int i;
char Text[1000];
printf("write the text:
");
gets(Text);
for(i=0;i<=1000;i++){

I need to assign unique integer values to words in a dictionary that have the same alphabets, for example 'act' and 'cat' should have the same integer value. Would just adding the ascii values of the letters be sufficient?

How to get a txt Outfile to display a Checksum.
Code:
ChecksumFileDisplay = fopen(ChecksumFileDisplayPath, "r");
fprintf(ChecksumFileDisplay, BigEndianChecksum);
That's what I have but it doesn't like the fprintf function because BigEndianChecksum is an unsigned int and it wants a pointer to a const char. Is there a function similar to this that will display an 8 digit integer in a txt outfile?

I have a report that's generated by a piece of software, and (I'm assuming because it was intended for Linux/Unix) when I open to read it in notepad, it has a bunch of funky symbols in it, and incorrect line feed characters instead of returns that windows uses.
I looked at the txt file with a hex editor and can see all the hex codes for the symbols I want deleted. One of the symbols 0A.
How can I do a "find and replace" command but do it with hex codes? These symbols cant be simply placed into my code file because VS does not know how to interpret it.

I would like to extract and analyse the data but the data behind the NUL entry is not accessible for me maybe due to the fact that NUL normally marks the end of a line. Is there a method to remove the NUL entries in this text file?
