I am trying to use to save the current date and time into a char array using this code:
char current_time(char *date){
time_t result = time(NULL);
date = ctime(&result);
return *date;
}
main{
[Code]...
now when I output the date char array into a txt file I only get gibberish.
lets say I have a char array with four elements but only one char is used, does it write four elements or just one?

View 5 Replies View RelatedI am trying to fill an array with blank spaces and instead i get the number 32 over and over, i think this is the ANSI code for that character. how do i get the character itself?
char values[max];
for(o=0;o<=max;o++)
{
values[o]=' ';
printf("%2d ", values[o]);
}
printf("

How do I convert just the number from position 4 to 15 from this char array and convert to int and save to variable
char numbers[]="54155444546546545643246543241465432165456";
the real char got 1000 digits this is just example how do i convert chars from numbers[4] to numbers[15] and save them as one number ? in this case i will get int x = 5444546546545643 as u can see char numbers as a example above
I'm working in a web aplication in c#, vs 2008, framework 3.5, I need to assign a value to a var, in this case "problemas", when I tried to save the value that I have in the checkboxlist, it does, but if don't selected, can't show 0, besides if I change the value "problemas = 9" to problemas = 111111" doesn't works.
protected void ckblProblemas_SelectedIndexChanged(object sender, EventArgs e){
int problemas = 0; {
if (ckblProblemas.SelectedValue.Equals("9")) {
problemas = 9;
} else {
problemas.Equals("0");
}
I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.
this is the entire code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
[Code]....
at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.
I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?
joe bob joe bob
seg fault*/
/****************************************************************/
//This is here to show my struct/playerInit

View 1 Replies View RelatedI am trying to develop a GUI using MFC, but I am having trouble using CFiledialog to save a file. The problem is, the file is not getting saved to the folder when I use the CFiledialog. Below is the code I am using.
Code:
CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)

After the file dialog opens up, I enter the name of the file and select OK button. But the file does not show up in the directory I am saving to.

So I try to sort an array with qsort and then save the new order, so this means if I have a list like:
4 3 7 2
[0] [1] [2] [3],
after sorting it becomes:
2 3 4 7
[3] [1] [0] [2] <== this is what I want to have!
Code:
void qsort_my(int *a, int l, int r, int *array_order) {
int j;
if( l < r ) {
j = split( a, l, r, array_order);
qsort_my( a, l, j-1, array_order);
qsort_my( a, j+1, r, array_order);
[Code]...
But my problem is that the list gets sorted, but the indexes do strange stuff. When I run with this list:
4 8 14 1 2 1 22 12 2 14
Pos: 0 1 2 3 4 5 6 7 8 9
I get:
1 1 2 2 4 8 12 14 14 22
Pos: 1 0 1 0 0 5 7 6 5 6
And with some printfs I noticed, the first two calls of split it is fine but then strange things start to happen, what I do wrong?
I have this file that I would like to read into a multidimenstional array in c#: file. If I take the first set of lines as a first example, I would like the print_r to look something like this:
Array (
[SiiNunit] => Array (
[0] => Array (
[nameless.2BB8.4FB8] => Array
[0] => Array (
[bank] = _nameless.2917.43B0
[player] = _nameless.2813.6928
[companies] = 312
[code].....
this (as I expected it to) wrote each line of the file into a 1d array however, I would like it to write it to a multidimensional array.
I am trying to store each value of a column from a text file into an dynamically allocated array, which needs to be globally declared for further usage in the program.The input textfile contains the following:
34932 13854 13854 2012-01-07
172098 49418 53269 2012-01-07
I have written the following code:
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
}
[code]....
The commented printf line gives the entire values of the column, which proves that the file is correctly being read.But on compiling this program I get both compiler warnings and finally segmentation fault.
I wrote a Simon game, and wanted to save the top 10 scores. I was working right, until I decided I wanted to still be able to read the file if someone enters a name containing spaces. Now, the results aren't right.
void FillScoreList(string Simon_Names[], int Simon_Scores[]) {
ifstream Simon_HiScores("Simon_Data.txt");
if (Simon_HiScores.is_open()) {
for( int x=0;x<10;x++){

Even without trying to read names with spaces, I'm getting
dad 1

... either a long number or a zero. No names
I have most of the code working properly, but I'm having trouble with a certain area. Currently I have multiple 2D arrays. One is a char array and the other is an int array. In the int array I have to find the max number in each column, which I've done. The problem is, I need to print the max number's row in relation to the char array's row.
For example,
Code: int array[2][3] = {60 50 30 0 100 1}
The max numbers are 60, 100, 30.
char array[2][length+1] = {nameOne nameTwo}
How it needs to print:
nameOne has max score of 60.
nameTwo has max score of 100.
nameOne has max score of 30.
I just can't understand how to compare the two arrays in the right way, so it'll know that nameOne is associated with the numbers in row 0 and nameTwo in row 1, etc.
What I'm trying to do is have the user input a hex number this number will then be converted to a char and displayed to the monitor this will continue until an EOF is encountered.I have the opposite of this code done which converts a char to a hex number. The problem I'm running into is how do i get a hex number from the user I used getchar() for the char2hex program. Is there any similar function for hex numbers?
this is the code for the char2hex program
#include <stdio.h>
int main(void) {
char myChar;
int counter = 0;
while(EOF != (myChar = getchar())) {
if (myChar == '')
[Code] .....
This is what i want to the program to do except it would do this continuously
#include<stdio.h>
int main() {
char myChar;
printf("Enter any hex number: ");
scanf("%x",&myChar);
printf("Equivalent Char is: %c",myChar);
system("pause");
return 0;
}
I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.
decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.
whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?
Code:
/* * File: main.c
* Author: david

* Created on May 23, 2013, 11:57 AM

I have the following code which attempts to assign a u_int8 array of 256 to an unsigned char[256]:
Code:
unsigned char testData[256]=pSample->data;
I get the compilation error:
error C2440: 'initializing' : cannot convert from 'const uint8_t [256]' to 'unsigned char [256]'
What is the safe way to cast or convert here?
I am writing code to multiply two int arrays and in my one function i am trying to convert the char array into an int array. I have tested many parts however i can not find the problem.
Code:
struct integer* convert_integer(char* stringInt){
struct integer *converted = malloc(sizeof(struct integer));
int length, i, *ints;
ints = (int *)malloc(10001 * sizeof(int));
length = strlen(stringInt);
printf("stringInt: %s with length of %d
", stringInt, length);
converted->size = length;

Is it possible to do?
I have an int array with the binary value of a char. How to to turn it into a char? I can transform it to an int but then I'm stuck.
Code:
#include <stdio.h>
int main() {
int a[260] = {0,1,1,0,0,0,0,1};
char buf[260];
int b=0;
for(int i=0; i<8; i++) {
b=10*b+a[i];
}
itoa(b, buf, 10);
