How can i play a mp3 file in the background?How can i rule the volume of the mp3 file?why does delay(0.25) doesnt work in this code?
Code:
FILE *datei;
char line[ANZAHL][LAENGE];
int i ;
datei = fopen ("song.txt", "r");
if (datei != NULL){
for(i = 0; i < ANZAHL;i++) {
delay(0.25);
fgets(line,LAENGE,datei);
printf ("%s

In the assignment we are forbidden to use fscanf(). I have been trying to get this to work, but I've started to realize that I do not have a complete understanding of what strtok() actually does. I'm getting this warning when debugging: "assignment makes integer from pointer without cast."
This warning happens when assigning str to goal and assist, and I think it is because they are, when dereferenced, integers. The code below correctly assigns the name into the correct spot, but leaves nonsense data in the goal and assist arrays.
ex:-7880, -7888 file example: NAME GOALS ASSISTS JOHN 1 2
Code:
void readLinesFromFile( FILE* Ptr, int* goal, int* assist, char** name, int lines ){/*
* Reads lines from files and populates the arrays with the corresponding info.
*/
int index;
char hold[ MAX_LINE ] = { 0 };
char* str = NULL;

From what I understand about strtok(), it returns a string, and takes in a character array and a key value that tells it when to stop. In the online examples I've seen, they use NULL in the first field. I'm not sure why.
My code is given below:
cout<<"1. runtim";
cout<<"2.tims";
cout<<"Your selection will be automatically neglected within (function to be inserted for time ) ";/* insert timer here */
cout<<"What kind of process u need to do";
.
.
.
.
I have 2 questions
1.the timer function has to be such that when any key is pressed in between the specified time its has to stop its counting and go to the nest line and functions . i checked sleep function but if any key is pressed its does not break out of the sleep program and execute the next command
2.and if the timer has completely finished running then it has to skip few lines and execute the program .
I am trying to use fgets to read in a string, but keep getting a "no conversion function from std::string to char" error.

The way I have come to understand this is that if you use the following line of code:
PlaySound(TEXT("C:WindowsMedia
otify.wav"), NULL, SND_FILENAME);
The sound file would not play if it is not in the same location on the other computer. Am I correct? Assuming that I am, I have added the file that I wish to play as a resource in my project, but I can't figure out how to make it play. Looking at MSDN (and other resources) I found the following snippet:
#define MAKEINTRESOURCE
PlaySound(
MAKEINTRESOURCE(L"notify.wav"),
GetModuleHandle(NULL),
SND_RESOURCE);
I get no errors when I build the program, but no sound plays when I run it. I have tried for hours now to figure this out (which is usually enough time for me to sort through the problem) but I have met with no success. This leads me to believe I am either completely off in my assumptions, or I am making a silly mistake.
i want to create a program (in c++ or c#) that will play mp3 files but also display a word file with the lyrics of the mp3 song playing. so if i choose a mp3 file from a list, the lyric file for that song should also be displayed. i have all the mp3 and lyric files saved on the computer so my problem is how can i link the files?

View 4 Replies View RelatedWhen you press a key it automatically delays a bit then starts repeating without delay.
The second key pressed action comes with a delay and i want it to start repeating without delay. And could not find anything useful.
I might not be able to tell what i want exactly. Ok press simply a key and don't release it in a text editor. You will realize a delay at second character showing up.
for example i have
int count = t1;
while(count>counter){
Sleep(delay);
Int32::TryParse(textBox2->Text,add);
result = result + add;
counter = counter + 1;
Problem is that sleep stops all program for specified time, Is there an alternative to sleep that would only stop part of code or can i use sleep different way to specify what it pauses?
So I'm in the process of building my 2D game in Allegro5, I'm building a side platform game and at the moment I have a sprite being able to walk left right and jump. What I want to do is put a time delay on the jump function so that when a user presses the jump button and the sprite has carried out the jump function I want there to be a 1 or so second delay before the jump button actually carries out the jump function again.
I have quite a bit of code so not sure what bits to place in here, I'm more looking for a way of doing this, so providing me code isnt really needed just a way it can be done.
Things that might be useful to know:
At the moment I have a timer initialized in allegro which is used with my FPS int to mean that my game runs at 60FPS.
I have a bool bIsOnGround which maybe could be used into this, I'm not sure...
When I use the following handler to handle and mix multiple channels, I get about 1 time unit sound, 5/6 time units silence.
//The volume conversion!
#define VOLUME_PER_SOUND(volume) ((SDL_MIX_MAXVOLUME / 2)*volume)
//Ammount of times to multiply the buffer!
#define MULTIPLIER_BUFFER 1
/* This function is called by SDL whenever the sound card needs more samples to play. It might be called from a separate thread, so we should be careful what we touch. */

(I'm working with 44.1kHz stereo PCM streams)... I've multiplied the stream some times, but to no effect (see the c<MULTIPLIER_BUFFER loop arround the mixing)...
I want to calculate the total some of delay pf receiving Side Packet . Code is as Follow ..
What is weird that even if i invoke a sleep of 2 sec ,than its show delay always zero. Delay will be in microsec ..Is there any problem with logic or anything else..

Currently I am doing the first exercises from Illustrating C. The exercise that I am trying first is the one where someone can input degrees and the program will be able to put those in to sin or cos. Im trying to use fgets to take input from the user. the answer can only be sin or cos. Im having trouble with how to get it to work.
My goal is to have the output of the choice sin or cos. Store that choice. proceed to ask what the degrees are from the user. then i would have the degree input multiplied by pi/180 converting it to radians and having the program compute it that way

View 6 Replies View RelatedI am trying to write a terminal-like chat application in Linux. I would like to use a FIFO queue to print out the messages in terminal. The queue would be populated from 2 sources- stdin and messages sent from the other user over TCP. I have meet an obstacle that I cannot handle...
Lets say I would like to take user input using fgets and put it into a buffer. Then queue it if the buffer is not empty or print if it is. The problem is that when I use fgets or scanf, my input is instantly printed to the terminal..If i do:
Code:
fgets(message, 100, stdin); printf
("%s", message The string under message is printed twice :|. Is there a way to prevent this?
Code:
char line[BUFSIZ];
while ( fgets(line, sizeof line, file) != NULL ){
llen = strlen(line);
printf("%d - %s
",llen,line);
}
I get a full line printed but my llen is the size of my buffer. how do i get the total size om my line from the beginning to " "
Why will this code not work? It cashes the program on me once i get to it...
Code:
memset(&input, 0, sizeof(input));
printf("Enter your firstname: ");
pinput = fgets(pinput, BUFF, stdin);
strncpy((pct + *pctcounter-1) ->firstName,pinput , strlen(pinput) - 1);
Is it possible to fgets() the string (or word) only after a delimiter? I yes then how?
Example: Code: printer, scanner, machine
Also, how can I sscanf() a string with an indefinite number of sizes and assign it to only one variable?
Example:
Code:
str = "I Love C programming 9000";
sscanf(str, "%s %d", strvar, intvar);
Intead of using scanf("%d",&a) to take a input from the user,how to take a input using fgets(buffer, BUFFERSIZE , stdin) and atoi?

1. If the user matches the lottery in exact order , the awards is $100,000.
2. If the user input matches the lottery digits, the awards is $50,000.
3. If two digit in the user input matches a digit in the lottery, the awards is $30,000.
4. If one digit in the user input matches a digit in the lottery,
the awards is $10,000.
Sample:
The winning number is 865.
Your ticket is 865 then 100000
Your tickect is 686, or 568,.. all digits are right but not in order
You get 50000
Your ticket is 860, or 186 .. then 30000
Your ticket is 800, 706, 600.. just one digit much you get
10000
Else
0
Im using if/else statements. Which syntax would I use to figure out the limit between 100-99?
I have a Blackjack game that allows users to create a login account and it keeps track of their bet amount, and total bank,etc. How can I connect the program on 2 or more computers so that people can play together?
(A) How would I code it? (B) Can I just connect a USB or HDMI and use the appropriate code? (C) Do they need to be executables instead of just running out of Visual Studio? (D) Can this maybe done over Wi-fi? (E) Or is this something more complicated like over a VPN?

View 2 Replies View RelatedI have prepared a file through the use of following code
Code:
fprintf(file2, "%i %i %i %i %i %i
",
msg_id,
msg_size,
msg_period,
msg_deadline,
msg_producer,
msg_comsumer
);
As one can see, this file has tab separated integer entries. The file is written correctly, let us call this file "msg.txt".
I face the problem when I read this file, using fgets as follows:
Code:
char singleMessage[100];
while( fgets(singleMessage, sizeof(singleMessage), file ) )
{
puts(singleMessage);
sscanf(singleMessage, "%i %i %i %i %i %i
",
&first, &second, &third, &fourth, &fifth, &sixth);
fprintf(stderr, "first: %d, second: %d, third: %d, fourth: %d, fifth: %d, sixth: %d
",
first, second, third, fourth, fifth, sixth);
}
but fgets only retrieves until the first, i.e, if the first line in the file reads:
788004425
fgets returns only 78.
Does it have to do with how the file was written in the first place.
I'm new to C/C++. I am attemping to use fgets and sscanf to read a line of input, and confirm it is a positive number.My code works great, except for the case of a negative number. When I enter a negative number, my while loop seems to run infinitely, with stdin providng the same input over and over again.
Here's the code snippet:
Code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#define TEXT_LEN 64
void foo() {
char* inStr = (char*)malloc(sizeof(char)*TEXT_LEN);
memset(inStr, 0, TEXT_LEN);
}
