I am receiving a max of 50000 bytes from a socket.
char packet1[50000];
recv(Socket, (char*)&packet1, 50000, 0);
What is the best way to read those bytes? Let's say I need to see if bytes 14-15 and byte 16-17 equal each other.
Only thing I can think of is to create a buffer array of 2 chars, and feed the bytes into those and compare them. Is that right?
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.
lets say we have a txt that contains this
| | | | |*| |
| | | |*| | |
and that symbolizes a 2x6 char array and we want to take only the symbols inside the || and place them in a 2x6 char array. how do we do that?
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).
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:
Code:
#include <stdio.h>
#define sizeOf 7
//char personName( char * name[] );
char printName ( char * name[]);

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.
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 wish to read an excel file which contains the table shown at the picture below.
I don't really know how to code the direct storage of the values in the appropriate array.
For example I wish to store the countries in an array of a string type.
could I have some piece of code which illustrates it (I mean the reading of an excel file and the direct storage of his value in an array).
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

And it works , but i need to hit ENTER two times when i have 3,5,7... chars to print result.
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;

I am trying to convert some chars to UTF-8 strings...

Basically i want to keep looping until i enter an a or A (also does this apply to if statements as well?)
I'm trying to put in my messages, in my program, some special chars but when i try something like the following code, i get the output below.
#include <stdio.h>
int main( ) {
printf("Trying this char: %c", 160);
printf("Trying this char: %c", 163);
return 0;
}
Output:
Trying this char: �
Trying this char: �
How can i put those special chars? I would like to use: é, ú, ç, à, Ú, À, ...
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?
I have a problem with my code. I just have to reverse the chars of a string, but it adds a /n that I can't delete.

I found this method
Code:
TCHAR win_getch()
(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() {

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.
View 1 Replies View RelatedFor 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
if (scanf("%d", &n) {
printf(" %d", n);
}
else {
printf("Error);
}
and it sorted correctly.
im trying to read in 1 array and get 2 as outputs from 3 different functions.my read array is easy enough were im getting confused is how to read that array, separate it and take out only the parts i want and place them into a 2nd, then again a 3rd array.i have the following so far:
Code:
#include<stdlib.h>#include<stdio.h>
#include<unistd.h>
#define SIZE 10
}
[code]....
this compiles without a complaint, but when i go to run it no longer responds after taking the 10th element (well 9th if counting from 0).I think i have the if correct for the even odd section, but when i try to populate B or C array with the output of that if statement from A is were i think things are dying...
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.
So in what way should I do it? Loop, array, ...?
current functions are:
char *createEnvironment(int width, int height, int numWoodChips);
void printEvrionment(char *environment, int width, int height);
need to be:
int* createEnvironment(int width, int height, int numWoodChips);
void printEvrionment(int* environment, int width, int height);

#include <stdlib.h>
#include <time.h>
