C :: Combinations - Putting Strings Into Array From A File
Apr 4, 2014
The first line of my input file is going to contain some number "T" which will represent the "combination length" of a list of random words. (In this case, they are Taco Bell items). The first number on the second line represents the number of unique items on the menu to get, and the second number on the second line represents the number of unique items that are supposed to be bought.
Basically the input will look like this: 2 3 2 taco burrito nacho
And the output looks like this: burritos nachos nacho taco burrito taco
This is what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
int main(void){
int N, T, K;
char menu[N][20];
[Code] .....
What I am trying to get working right now is just to scan a file and put the strings into an array so then I can work on sorting the array. How can I add strings from a file into an array?
I am at a loss with an assignment. I am supposed to read from a text file, with an input of something like this: alphaproleone,stroke,42 1 and Store it into an array of structures and then output it with each word/number starting on a new line. My current code prints out only the first part, and the "a" in alphaproleone is the actual number "21".
#include <iostream> #include <string> #include<fstream> #include<iomanip> using namespace std; typedef struct drugtype { string name, target; int effectiveness, toxicity;
I am trying to put pieces of a csv file into an array, but i only want to put certain pieces of it. This is the information that i have
Player,Current Team, Age , Nat , Position ,From,To,Transfer fee Gareth Bale, Real Madrid,24,Wales,RW,Tottenham,Real Madrid CF,91000000 Edinson Cavani,PSG,26,Uruguay,CF,SSC Napoli,PSG,64500000 Falcao, Monaco,27,Columbia,CF,Atlético Madrid,Monaco,60000000 Neymar, FC Barcelona,21,Brasil,LW,Santos,FC Barcelona,57100000 Mesut Özil, Arsenal,24,Germany,AM,Real Madrid ,Arsenal,50000000 James Rodríguez,Monaco, 21,Columbia,RW,FC Porto,Monaco,45000000
With this i want to skip the name and team but need age.
I'm trying to pass several integers into the array idAr[10] from an input file using a for loop and then having them output on the console. The output should look like this:
#include <iostream> #include <fstream> using namespace std;
How to find all possible combinations of coordinates on a 2d grid with a given sum. The sum is not fixed!
E.g. N=nxm=25 thats our grid.
The sum=distance between points on a grid.
For two points distance=|(x1-x2)+(y1-y2)| point A(X1,Y1) B(X1,Y1)
My interest is to know how to find the combinations of coordinates with a given sum, it doesn't matter how many points are there.
If i enter the sum e.g sum=7 and the program has to show all possible combinations which gives the sum of 7 the number of point does not play in row they might be two or maybe more.
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)
I am having trouble putting data from a txt file onto a vector of a class. For instance.
class employee{ setname(string) { some code } getname () { some code } setid(int)
[Code] ....
How would use my setname function in my class using my vector? I tried doing vec[num].setname(tempname) but it doesn't work. I know it does not work because I have to use .push back for a vector but I don't know exactly how to pushback using the set name function call.
I am trying to use a combination of windows batch scripts as well a C++ program to put users data into one single .CSV file. Right now, I have a batch file that will output data from the command line into multiple .txt files. These files are mac.txt, serialnumber.txt, computermodel.txt, and computer name.txt. What I want to do, is to have users run the batch file, which will in turn run the .exe C++ file which will concatenate all their data into one file, computerinfo.csv. The file format for this file would be to have the mac address, serialnumber, computer model, and computer name all in their own column.
My main issue is that these individual files don't have the format that I would like, but based on the command prompt functions, there isn't really any good format. For example, the mac.txt file has the following format:
Physical Address Transport Name =================== ========================================================== xx-xx-xx-xx-xx-xx DeviceTcpip_{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} yy-yy-yy-yy-yy-yy Media disconnected zz-zz-zz-zz-zz-zz Media disconnected
but all I really want is xx-xx-xx-xx-xx-xx
The other files have other issues with format, but if I can figure out this one then the others should be a piece of cake.
Also, I want the output of this to all go in one row, and as other users run this file, they will go into new rows without touching the rows above.
In a program, I have a text file (called MyDictionary.txt) which has thousands of words in alphabetical order. I need to make a C program that reads in this text file and then makes an array called char Words[# of total words in the text file][length of longest word].
I am trying to read strings to an char array from an .exe file and then i would check some of the strings, but the problem is that the only thing that is read from the file is the first string (MZ) and an 'square' that is some incorrect character. I am using fread to read from the file. Here is my code:
I am having problems figuring out how to place a list of strings from a text file into a multidimensional array that is something like words[NUM_WORDS][MAX_LEN]. I already run through the file once and count the number of words in it. I have tried a number of loops using fscanf and fgets, but I'm not sure if I am using them right -- this is my first time using them. The text file is a list of words in a dictionary, so the wordCount is about 45340.
Here is my code:
#include <stdio.h> #include <string.h> #define MAX_LEN 46 int main(){ int wordCount = 0; FILE *inputFile, *outputFile;
[Code] ....
Like I said, the wordCount portion works. I added the printf statements at the end to see if anything was being saved, but it just prints two new blank lines. New to file reading and writing.
The code below will generate combinations of numbers from 1 to 25 in an 15 numbers array. The only filter I've applied is that the sum of all the numbers in the vectors divided by 15 needs to be between 13 and 14. I would like to count how many consecutive numbers there are in one combination, so that later i can apply another filter.. for example:
A few days ago I got a "bright idea" to see if I could match a string, with an arbitrary length from 1 to 12, to its formulated sequence by using an algorithm to find all possible combinations of the integer combinations from 0 to 9 at each length (1 to 12).
Example: Desired numerical combinations from integers 1 to 3:
And so on until the nth length (in my case a length of 12).
First off, I would like to say that this is not as easy as I thought. I clearly underestimated the problem seeing as I've spent hours attempting to write a working algorithm, but feel like I've made no progress.
I can't exactly explain this one. It works if the length is 2 or less; however, the order of the output is horrendous.
Attempt 3: I tried using recursion, but only found myself getting more and more lost the further I tried developing my function. Cannot find my work for this attempt.
I would really like to figure this out on my own, but I am very stuck as you can see. I also lack time that I can spend working on this since im a full time student.
On my program I use a counter to count to 10, then i ask for a string, in this case "yes" or "no", during the count, i want to keep the user from putting inputs in, due to the fact that if they put both "yes" and "no" before the program reads the string.
I need to create a function that outputs all possible binary combinations. I'm really stumped on this. I have to do it with nested loops, and am not sure how to go about it. Below is what I tried so far.
I wanted to create a 5, 3 combinations. i know how to calculate to get the number of combinations 5 3 would have (which is ten), but it seem it's a bit harder for me to print those data ...
I am trying to write a program for printing all the combinations of a string. Why this program is giving the error message.
"First-chance exception at 0x761bc41f in word.exe: Microsoft C++ exception: std::out_of_range at memory location 0x0026f6b4.. Unhandled exception at 0x761bc41f in word.exe: Microsoft C++ exception: std::out_of_range at memory location 0x0026f6b4.." when i try to run this in MVS 2010
How to get all the possible combinations for 4 digits from a 5 digit number. I need a pair that has both 5 digits and four digits. their sum must be equal to a five digit user input. i.e.
user input : 14690 output: 14690 has pairs 12345 + 2345 2345 came from 12345 lets say that x = 12345 and y =2345 besides y == x%10000
other formula can i have since if i use % and / i will have a lot of declarations....
how to write a password cracking program that will try all possible char combinations for just two chars (without duplicating any combination guesses). Obviously, there would only be 4 possible truth table combinations for two boolean values, but how would a person calculate the number of all possible combinations for two values with 70 different possible chars?
Note that there are 70 chars in all specified above.
It will require much more than a simple truth table to try every possible char combination (especially if the password to be cracked is 2 or more chars). Using this guy's code: [URL] ..... as a starting point, I'm writing a program that will crack a password with a length of just 2 chars.
