I thought that if I were to access Buffer1 via BufPtrs[0], I would simply just put an * to it before printf()-ing or store it in a char[] (equivalent to a string).
I need to calculate how often each letter appears in a text file from a function that is called from main() with an array of pointers to char and how many pointers there are in the array. The code i have so far is:
I get no errors and it runs but it gives me the wrong output. I know my array is correct because when i print it in main() it is correct but each letter is incorrectly counted. When i give it the input .txt file of:
This is one line of a string This is another This is the third one Wow heres another one It counts a as 8 b as 1 c as 3 etc.
I have hand traced it and cant figure out why it isnt giving me correct values
I am trying to write a program for a library system that allow stuff to add, remove, view and delete customer. i try to use file to store data and i open the file in mode read then i store then i put the content of the file into a structure. now the problem started it is only showing me haft of the content and here is the coding.
#include <stdio.h> # include <windows.h> # include <stdlib.h> #include<string.h> #include<conio.h> void search(int s,struct books eli[20]); void view(int x,struct books eli[20]);
how could i allocate memory is only needed for every string(as long as it is)? Cause in my code i allocate memory for 100 strings and for 10 characters for every string.
I have wrote the code below that compares to strings and sees if they are equals doesn't matter the order of the words . In the question we where asked not to use any library functions like the string functions in <string.h> and we have to do that all with pointers . I debugged my code and for some reason the first loop in the function keeps looping ...
#include<stdio.h> int IsEqual(char* str1,char* str2); #define SIZE 20 void main() { char str1[SIZE]="my name is monaya",str2[SIZE]="name monaya is my"; if (IsEqual(str1,str2))
This is my program and i dont know what is the better strategy to display the output perfectly align with the title, when i input a long variable or short the variable move and it does not align with its title. what can i do.
#include <iostream> #include <string> #include <string.h> #include <cstdlib> #include <cstring> #include <iomanip> using namespace std; struct book {
why when I print out "array[2]" nothing prints? It just prints blank space. My file definitely has text in it, but when I try to assign "text" into the array of pointers it won't show any text. I know fgets() appends a newline at the end of the string, not sure if that has anything to do with it, but I've tried printing everything that should be in "array" with a for loop and I get nothing.
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];

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?
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.
I have written this code, and at first glance it does what I want, however I am worried that
a) I am overwriting the array that is apssed from chord.getPattern() b) Im getting a memory leak that I want to get rid of, and c) is there generally a /what is the neater way to do it:
Code: uint8_t* ChordBuilder::invert(uint8_t count, Chord chord) { temp = chord.getPattern(); chord.invert(true); //TODO count is how many times to invert. Moves root aswell however
for (uint8_t i = 0; i < count; i++){
[Code] ....
temp is a member variable of ChordBuilder - and is expressed as: Code: uint8_t* temp; I dont want the pattern that chord stores, and passes with getPattern() to change - I fear it is at the moment?
I would rather not use the "new" but I cant think how to get rid of it, however Im not sure where I would need to put the "delete"?
#include<iostream> #include<string> using namespace std; int main(){ char char_array[10]; int ascii_array[10];
[Code] ....
I have been trying for a while to copy a string to an array, i know i can copy an char_array element to a string but its with a two dimension. How can i do this? i want it to be user entered.
I am trying to figure out copy constructors for a dynamic array and I am definitely missing something. If I go into the copy constructor routine during debug, the values appear to be correct but they don't percolate up to the newly created object. I'll post a portion of the code below:
Code:
// include header files for the classes that are being used #include "stdafx.h" //
NOTE: THis reference must be added to all cpp files in Visual Studio Express 2013
#include <iostream> #include <string> #include <cstdlib> #include <map> using namespace std; const int ARRAY_SIZE_DEFAULT = 32; class vectorOfInt { public:
[code]....
The size of c is 0. Values of a were not copied to c, although they appear to do so within the copy constructor routine.
my question is located as a comment beside the last printf ! ? check the comment near the last printf the comment is ==>here i get a sequence of numbers the question is how can i copy this sequence to an array and the print the array out ?
Code: #include <stdio.h> #define N 30 #define n 100
[Code]....
here i get a sequence of numbers the question is how can i copy this sequence to an array and the print the array out ?
I am trying to compare 2 strings of characters The users input containing 5 chars is compared to a table If the input is already be existent in the table the index of those chars in the table is printed Quest: how to copy the result of a printf() into an array ? The last printf() gives a sequence of numbers and I am trying to save that sequence to another array for further operation ! I have not been able to do that so far even with tmp[]=i ;
Code: #include <stdio.h> #include <string.h> #define N 30 #define n 100 int main (void) [code]....
