C :: Scanning A File With Words And Int / Float Numbers
Dec 1, 2013
scanning a file with both words and INT's/Float numbers. This is the file data here.
15 25 200
3 10
17.99 22.99 109.99
100 2 4
5.99 99.99 20.00 49.99
10 10 10 10 10 10 10 10 10 10
3.99 5.99 7.99 8.00 5.00 5.00 5.00 6.00 7.00 9.99
[Code]...
What I'm focused on is reading in the first three numbers which I already have with fscanf and then reading in BUY TICKET with the digit afterwards. My problem is that I don't know how to reach that part of the file without scanning in something I don't want to. Also, how would I scan the number after scanning BUY TICKET? Would it be something like using %s and %d right afterwards?

This is the first time I have encountered a "no stack." error giving me a seg fault. Anyhow, I am scanning words into a binary search tree and it is giving me a seg fault.
Here is the file (words.txt):
4
bravo
alpha
gamma
delta
Code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
typedef struct node_t{
char *word;
struct node_t *left;
struct node_t *right;

I'm new to programming and I have a question about scanning numbers from a .txt file into a .c file. I have an array that has 50 integers and I want to read in 50 numbers from a .txt file. What would I type in on the command line to get the array to read in the .txt numbers?

I need to write a program that reads four float numbers from the input.txt file, then it prints out the greatest of the four numbers into the output.txt file. I did everything, but the numbers don't print out.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;
float number1, number2, number3, number4;

I have a code able to import a file containing words and numbers to a linked list, but I also need to sort this linked list alphabetically. I've done research on this involving bubble sorting, but no explanationcan achieve this objective.
Below is the code that can only put the file into linked list:
Code:
#include<iostream>
#include<conio.h>
#include"U:C++WordClass2WordClass2WordClass.cpp"
#include<fstream>
#include<vector>
#include<string>
using namespace std;

I need to scan a .csv file that contains the following info:
programming,03,60,141,01,W,2015
programming,03,60,141,30,W,2015
Algebra,03,62,102,02,S,2013
Religion,08,98,938,20,F,2014
So i made a struct:
typedef struct CourseInfo {
int courseID;
char courseName[50];
char courseCode[13];
char term[7];
} courseinfo;
Where course code is the 4 numbers after the name together and the term is the letter and year in the last two pieces of info. I got this to work:
int main() {
FILE *p;
p = fopen("input.csv", "r+");
if(p == NULL) {
puts("The file could not be opened");
[Code] ......
But lets say i dont know how many lines i have in my file and i want to count them and then use that size for my array so i tried this by:
int main() {
FILE *p;
int lines = 1;
char ch;
p = fopen("input.csv", "r+");
if(p == NULL) {
[Code] .....
But the second program is not working for unknown reasons. I do not get any errors but its not scanning the info because when i print the info later on it prints out random symbols.

I'm trying to read from a header file to take the image dimensions and other variables but I don't understand how to iterate through the "key" so it saves each line.
This is what the header file will always look like:
!INTERFILE :=
!imaging modality := nucmed
!version of keys := 3.3
;
!GENERAL DATA :=
[Code].....
Ideally it would just skip the keys that aren't wanted and keep moving through the lines. Should there be a for loop for the key (and if so, how does that work with pointers?) or should this method just be scratched...

I need to make a program in which the output must be like:
I=0 J=1
I=0 J=2
I=0 J=3
I=0.2 J=1.2
I=0.2 J=2.2
I=0.2 J=3.2
.....
I=2 J=?
I=2 J=?
I=2 J=?

So I have a double array, where I'm inputting float numbers to certain points in an array. Sometimes, the numbers that are printed out are completely different from what I put in.Here is the part of the code:
Code: .
while( token != NULL ) {
num = atof(token);
test[j][i] = num;
printf( "
%s, i is %d, j is %d
", token,i,j );
printf( "number is %f
value test of i,j is %f
[code]....
Why the float num prints out fine, but when put into an array becomes garbage?I'm taking string values from a csv file and turning them into floats, but no problems seem to crop up there.I reset i when appropriate and increment j when needed, so I don't think my problems are from incorrect array values (though they might be)

How to convert numbers into words using ragged dynamic arrays? this is my solution:
int main()
{
char *Units[]={"ZERO", "ONE", "TWO", "THREE","FOUR","FIVE", "SIX","SEVEN", "EIGHT", "NINE"};
char *teens []={"TEN", "ELEVEN", "TWELVE","THIRTEEN", "FOURTEEN", "FIFTEEN", "SIXTEEN", "SEVENTEEN", "EIGHTEEN","NINETEEN" };
char *hundreds []= {"HUNDRED"};
char *tens []={ "ZERO", "TEN", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY", "SEVENTY", "EIGHTY", "NINETY"};
char *currency []={"Dollars"};

I am trying to read into a file that has something like
I have 5 apples and 9 bananas.
Sam has 8 apples and 6 bananas.
and I need to replace the numbers with words. For example I need to change the "5" to five and so on. The problem is that im not sure how to access and then replace just the numbers.
#include <iostream>
#include <cmath>
#include <fstream>
#include <cstdlib>
#include <iomanip>
using namespace std;
int main() {
ifstream in_stream;

Write a c++program that asks the user to enter positive integer numbers without points between 0 and 999. Then check the amount and print in words. You need to use dynamic ragged arrays..
This is my solution but I'm not sure if this is the right way for dynamic ragged array???:
int main()
{
char *Units[]={"ZERO", "ONE", "TWO", "THREE","FOUR","FIVE", "SIX","SEVEN", "EIGHT", "NINE"};
char *teens []={"TEN", "ELEVEN", "TWELVE","THIRTEEN", "FOURTEEN", "FIFTEEN", "SIXTEEN", "SEVENTEEN", "EIGHTEEN","NINETEEN" };
char *hundreds []= {"HUNDRED"};
char *tens []={ "ZERO", "TEN", "TWENTY", "THIRTY", "FOURTY", "FIFTY", "SIXTY", "SEVENTY", "EIGHTY", "NINETY"};

I was working on float and double data types and to see the results i wrote this program:
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
int main() {
ofstream outputF("output.txt");
double a = 1;
double outcome;
[Code] ....
Well I understand the part it cannot store infinite numbers. but if you take a look at the output for example (since it is too long i just added some of the outputs)
//---------------------
for the value of : 001
1
//---------------------
for the value of : 002
0.5
//---------------------
for the value of : 003
0.3333333333333333148
[Code] ....
if you look carefully at the value "5" and "10" results. it is awkwardly abnormal. which is something i couldnt understand. also it is the same with value "20", "25", "40", "50" and so on.

I have to complete a project that i want to read float numbers from keyboard and store them into an array of 10 elements.! Every time that a number stored into array i want to compare with previous one if they have +-10 difference .. I want to keep only 10 elements into my array so every time that i give value a[0] replace a[1], a[1] replace a[2],a[2] replace a[3]. . . .and a[10] deleted.. So when all elements of the array are similar with +-10 values print out the array.!

I am trying to read user input for recipe ingredients which must include a ingredient name, and may include a quantity and a unit. Example: Stone ground flour 2 cups or Sugar 1 Tbsp or Milk. The problem I am having is that the string gets cut off after a space when multiple words are used for the ingredient name.
cin.ignore();
string line;
getline(cin, line);
istringstream record(line);
string name;
string name2;
int quantity = 0;
string unit;
record>>name>>quantity>>unit;

I've reached a point in "Jumping into C++" where I need to make a program that converts input numbers into their word equivalent.
So far I've made it work for numbers 0-9999. I've tried implementing 10000-99999 but there are problems with the order of the words printed (57865 would print fifty thousand seven thousand eight hundred sixty five). But besides that, the program is absolutely enormous (for me) and I'm wondering if it can be shortened. Keep in mind I can only use loops and if statements so far. Here it is:
Code:
#include <iostream>
#include <string>
void extras(int e);
void digits(int x);
void tens(int xx);
void hundreds(int xxx);
void thousands(int xxxx);
//void tens_of_thousands(long xxxxx);

I wrote a code that counts numbers of words in a sentence, simply by counting spaces... but instead of showing a true number it shows a wrong number.

#include <conio.h>
int check(char eh[10000]) {
int he=0;
for (int i=0; i<=10000 ;i++) {

I can do the folowing:
float var1 ;
var1 = 9.12345 ;
printf("%.2f",var1) ;
the output will be 9.12. What if I wanted to save that as another separate float with displaying it on screen?
