C :: Putting Float Numbers Into Double Array
Jan 29, 2014So 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)
C :: Combinations - Putting Strings Into Array From A File
Apr 4, 2014The 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?
C++ :: Putting Text File Into Array Of Structures
Feb 14, 2015I am at a loss with an assignment.

My current code prints out only the first part, and the "a" in alphaproleone is the actual number "21".

C :: Program To Get Series Of Integers From A User And Storing Those Values Into Array
Feb 10, 2013The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.
I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.

C/C++ :: Compare Values Stored In First Array To User Inputted Values In Second Array
Oct 19, 2014Goal: Write a program that compares the values stored in the first array to the user inputted values in the second array.
In order to fix this error: [URL]...
I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:
cin>>a2[i];

C :: Linked List - Putting Info In A Struct
Feb 8, 2015I'm having a little problem where after reading a file I'm unable to update my struct with some particular info. It is actually a linkedlist. This is my struct:
Code:
struct node{
int id;
char name[50];
struct node *next;
}*head;
And in my Main function:
Code:
int main(){
int i, t_id, num;
struct node *temp;
char name[50], t_name[50], input_name[50], line[LINESIZE], *value;
struct node *head = NULL;
FILE * ifp = fopen("AssignmentOneInput.txt", "r");
[Code] .....
Basically in the while loop when I input something like this for updating numbers:
Code: temp->id = num; //These are numbers separated by a comma. or this:
Code: strcpy(temp->name,value); //These are names The program crashes
C :: Putting Functions / Headers In Separate Files?
Aug 2, 2013I have just learned about how one can put functions and headers in different files from the main() function. I was wondering if there is a rule of thumb of when and when not to separate the two, or if it's merely preference. Is there perhaps an "industry standard" regarding this, for those who program in C for a living?

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.
C/C++ :: Putting Computer Info Into CSV File - Batch Files
Dec 8, 2014I 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.
C++ :: Create Array Of Playing Cards / Assign Values And Suits Then Shuffle The Array
Nov 24, 2014I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';
} for(int a = 0; a <= numCards; a++) {

C :: Print Values Of Array From Function By Passing Array?
Nov 1, 2014I wanted to print the values of a array from a function by passing the array as well as the number of elements to be read. For a single dimensional array, this is how i have written it. It's pretty straight forward. I want to read 5 elements from the 5th element in the array.
Code:
#include<stdio.h>
void display(int array[],int size) {
int i;
[Code]....
With this code I want to print the five elements from the element present in [0][4].
But shows an error that
Code:
D:BennetCodeblocks CLearning CSingleDimentionalArray.c||In function 'main':|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|18|warning: passing argument 1 of 'display' from incompatible pointer type [enabled by default]|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|2|note: expected 'int (*)[10]' but argument is of type 'int *'|
||=== Build finished: 0 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|
I know when you pass a array as an argument it gets decomposed into a pointer, but with a multi-dimensional array this is not the case. how this works for mult- dimensional array's?
C/C++ :: Take Values From One Array And Searches For Their Index Position In Another Array

Aug 27, 2014Write a menu driven program that will fill grid with values between 1 and 100. Begin the program by declaring a array of type int. Then present the user with the following menu
Enter 1 to add

Flag an error when try to add to a cell that is not blank
Display the complete and nicely formatted grid when option 5 is selected
