I'm working on a homework project, and it requires me to read in a file of chars into an array, and then do stuff with that array.
Anyways, I have the first part written, where I'm just trying to read in my data.txt file, and I thought I had it written well. It compiles, but then it seg faults, and I'm not sure why. I used calloc for the array, but maybe I misused it? Or is it in my EOF statement? I'm still not sure if that's coded correctly. I need to get past this so I can start testing the other parts of my code.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char* argv[] ) {
/* Local Declarations*/
int i;
int *ptr;
char tempc;
I am trying to write a function to save the state of a tic tac toe game. It seems to be working well except the loop to read the chars in from a .txt file is running 18 times instead of 9 and thus overwriting the array with blank boxes. The code below is the part of the function I am having an issue with. Counter is being increased every time the second for loop runs which should be 9 times. However, it is apparently running 18 times with the first 9 runs filling newBoard correctly and the second 9 times overwriting it with boxes. how to fix it?
ifstream inputFile("file.txt"); char newBoard[3][3]; char a; int counter = 0; while(counter<=9) { for(int r = 0; r<3; r++)
I'm looking for a algorithm to search portions of string that have the same caracter. The only possible values are: a,n and g
Char index: 0 1 2 3 4 5 6 7 8 9 RESULT ------------------------------------------ Example 1: a g g g a a 0,4 Example 2: g g g a n n a 0,3 Example 3: a g g g g g g a 0,7 Example 4: g g g g g g g 0,6 Example 5: g g a a g a a a g 0,2,3,5,7,8
I am trying to convert some chars to UTF-8 strings...
Example:
std::string gethex(char c) { /* EXAMPLE if (c == 'é') return "%c3%a9"; I need a function that converts chars like "á, é, í, ã" to UTF-8 hexadecimal strings... */ }
[Code] .....
[URL] .... does it. Choose UTF-8, type some character and click 'Url Encode'.
I'm writing a school assignment that writes/reads user input into and out of a binary file.
I've gotten the write part to work, but now I need to be able to read that file back in and display it as a string.
I think I should be using fread() and read my file into an array of int's right? But when I try printing out that array I get a whole bunch of numbers that don't match the hex code in my file.
How do I read in a binary file and print it out as a string?
(below) on a website which is used for printing the characters as the keys on keyboard are hit i-e without hitting the ENTER key. This method is used in a while loop like this
Code: while ((c = win_getch()) != 13) {}
I wanted to know why is the character compared to
Code: 13 i-e Code: if((c = win_getch()) != 13) then do something
Code: /** * This function will simulate the getch() function from conio.h. * Note that this does not work for special keys like F1-F12, arrow keys, * even the ESC key does not seem to work with this function. * @return TCHAR read from input buffer. */ TCHAR win_getch() { DWORD mode; TCHAR theChar = 0;
As a part of a program I am supposed to write, I would like to receive a string from the user (for example: "Hi my name is Joe").
obviously, the string is inserted to an array of chars (arr[0]='H', arr[1]='i', arr[2]=' ',... and so on).
What I would like to do, is to put each word separately in each array cell (for example arr[0]='Hi', arr[1]="my"..., and so on). How can I do this? (I can not use any functions, unless I write them myself).
How to give input with text for this function.i already create function for this but i dn't know give input as non ASCII value(0-32) that Cobain with string or simple text.
For some reason my code is not couting right. My function is supposed to decipher some code that if it has multiple same chars then it drops one. Example aabbyfkk --------> abyfk. But it couts abyffkk . For some reason it is not getting rid of the extra f and k chars.
string decrypt (string encrypted) { string deleted, tmp; int i, pos, n, j=0, z; tmp=encrypted;
I was supposed to sort out an input, getting rid of chars and only using the numbers. So 5a6g7we87hj9 would become 567879. I might be wrong in some way, but I used
Program background: Ticket Sales Details You will sell tickets in advance and at the door. Prices for buying in advance and at the door will be given. Also, the total number of tickets sold in advance will be given. Each guest will have a unique number. If there are n tickets sold in advance, then these guests will be numbered 0 through n-1. As the event starts, requests to buy tickets at the door may be made and these guests will be numbered sequentially, starting at the lowest unassigned number. The maximum number of guests will be 1000. The first line of the file contains the following three values, separated by spaces: Cost of the presales tickets (in dollars), Cost of the tickets at the door (in dollars), and the number of presale tickets. The first two values will be positive real numbers to two decimal places and the last will be a positive integer.
The second line of the file will contain one positive integer representing the number of auction items followed by a positive real value to two decimal places (at most) representing the minimum bid increment, in dollars. The first value is guaranteed to be 1000 or less and the second will be in between 1 and 50, inclusive.
The third line of the file will contain all the prices of the auction items, in dollars, separated by spaces, in order. Thus, the first price is the price of item 0, the next price is the price of item 1, and so on. These values will be real numbers represented to up to 2 decimal places.
The fourth line of the file will contain the three following positive integers pertaining to the raffle: the number of raffle tickets available, the cost of a raffle ticket in dollars, and the number of raffle prizes. (It's strange to have raffle tickets that don't cost a whole number of dollars.)
The fifth line of the file will contain each of the values of the raffle items, in dollars, separated by spaces, in order. Thus, the first price is the price if item 0, the next price is the price of item 1, and so on. These values will be real numbers with upto 2 decimal places.
The sixth line of the file will contain ten positive integers representing the number of each of the drinks 0 through 9, in order, that are in stock.
The seventh line of the file will contain ten positive real numbers with upto 2 decimal places representing the price of each of the drinks 0 through 9, in order.
The eighth line of the file will contain a single positive integer, numEvents, representing the number of events that occur at the charity ball. These events are split into two groups: actions by guests at the ball and awards given (raffle, auction, person, totalrevenue). All of the actions precede all of the awards. You will produce exactly one line of output for each event described. Here are the formats of each event that could occur:
If a patron buys a ticket at the door, a command will be on a line by itself:
BUY TICKET k
where k is a positive integer indicating the number of tickets bought at the door. These guests will be numbered as previously mentioned. You are guaranteed that the total number of tickets bought, including presales, will not exceed 1000. This is what I have so far and I cannot figure out why it wont calculate the total revenue. I am not completely sure if it is even accessing the if statement in main.
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> #define N 1000
I am trying to make a for loop that will print out chars in an array while using a #define before main. My problem is that each name has a different amount of chars in it. How do you account for that when you are trying to define a size? For example, I am playing around with the numbers and I just put 7 in for size:
I'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:
Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word int CompareLetter(char array[], char guess, int numLetters) { int i;
[Code....
However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.
That code should make the size of the pointer (how many chars it can store) bigger but when i run it it show always 3 char positions while it should show N*M.
Code: #include <stdio.h>#include <stdlib.h> int main(void) { int M, N, P, i; scanf ("%d %d", &M, &N); P = M * N; char *c = malloc(P * sizeof(char));
Write a program that reads a group of chars till $. Then, compute # of vowels, # of digits, # of word and # of special chars. Your program should display all required results.
How do I detect garbage chars in a CString. Actually I'm reading some data from COM port. In some certain condition it will give some garbage as a version no. Now I need to show _T("N/A") in case of there is any garbage.
My solution is to check for a Valid char or integer. If found its correct else Garbage.
I'm supposed to create a program that will find the min/max values of two ints, doubles, and chars, It's not completely done but here's what I have so far.

I'm trying to write a program which prints a table of ASCII chars, I'm not really done with my thoughts on it but I already ran into the following error:
Error: cannot initialize a variable of type 'char' with an rvalue of type 'char (*)[16]'
Here's my code so far:
# include <iostream> using namespace std; int main() { char asciiTable = new char[8][16]; int nextSign = 0;
