C++ :: Verifying If The Number Is Special And Not Scary
Feb 22, 2012
Code:
Exercise. 1.5 A number is special if it is divisible (no remainder) by 15. A number is big if it is greater than 999. A number is weird if it is divisible by 5 and 6 but not 18. A number is scary if it is big or weird.
Write a program to check which of the following, 450, 540, 600, and 675 are special but not scary.
Declare four variables called special, big, weird, and scary and make suitable assignments to these variables as a number is tested.
I want to do it with a function, but it just output that everything is Special and Scary, and that everything values 4199536.
Code:
#include <stdio.h>
#include <stdlib.h>
/* Function */
int test(int);
int test(int a) {
int sc, sp;

I was trying to implement Floyd's cycle finding algorithm to find loops in linked list. I implemented my code using 2 pointers but I am not able to figure out why my output is always is 0 even though a loop exists in the code.

How can I view the number of bytes that have been allocated by using the malloc function?I tried:
mem = (float*)malloc(num*sizeof(float));
printf("The amount of memory allocated using malloc is %d.", mem);
Note: The variable "num" in my program is equal to 7.But every time I run the program, this value changes.

I am trying to make a program that will read in input in the following format:
| ...text... || ...more text... || ...still more text...|
i.e. every bit of "text" that gets read in is bracketed on either side by the "|" character.
The buffer that i read them into can be of a maximum length of 101 (100 characters plus a terminating null character); this is how I am currently reading in the input:
char readString [100 + 1];
while ( fscanf(infile, "|%1000[^|]|", readString) ){
/*... manipulate readString ...*/
}
How might I design this program so that, should any of the text appearing between the "|" characters exceed 100 in length, it exits and returns a warning?

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, ...

There are many libraries in C++, but how are they made?
For example: SDL, SFML, Open CV, STK
There are no special functions in C++ from which we can create such libraries, If I wanted to create a library that processes sound signals, how would I do that? How can I access the mic, speakers and process the signals.
Open CV processes videos but which functions does it use?

I have an array in a class with some numbers in a specific order. Now I want to create a set with references to that array ordered after the arrays content. I thought a solution could be something like
class Holder {
int o[10]= {1,5,7,2,3,8,4,9,6,0};
public:
set<int,my_order> m_s;
Holder() {
for(int i=0; i<10;i++) {
m_s.insert(i);
[Code] ....
How to create the my_order.

how to rearrange lists in an special manner.
I have heard about the hashset but I do not fully understand how that thing works or if it is the best option for this issue.
Basically I have 3 lists: LIST1, LIST2 and LIST3.
LIST1 is a set of xyz points and LIST2 shows how the points are connected (clockwise, counter clockwise, coolinear).
For example the fact that in the first line of LIST2 appears 0, 1, 2,-1 means that the points in LIST1 are connected as follows:
(0 0 128.588459085565)->(25 0 134.979628462965)->(0 0 134.979628462965)
Same for line2 of LIST2: 1, 4, 2,-1
(25 0 134.979628462965)->(25 0 140.100717207301)->(0 0 134.979628462965)
etc...
The value -1 at the end of each line does not mean anything but I need to keep it.
Finally LIST3 tells me if the points are connected counterclockwise (-1), clockwise (1), or coolinear (0).
The thing is that I want to get things as follows:
If the values of list 3=1 then I need to extract all the points in the list 1 that correspond to the value 1 in order. However the values in LIST2 cannot keep being 1, 4, 2,-1 they need to be reorganised starting by zero. Expected result in LIST2= 0,3,1,-1.
We need to do this for each value in list3 (1,-1 and 0).
The idea is to get 3 groups of values:
- Group 1 including all the values that are clockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 2 including all the values that are counterclockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 3 including all the values that are coolinear (list3) with the points in order in list1 and showing connections starting from zero on in list2.
The idea is to be able to print 3 files in the following way:
FILE1:
Points which are clockwise in LIST 1
...
Connections of those points in LIST 2
...
FILE2:
Points which are counterclockwise in LIST 1

Let assume that there is an array of integer numbers in the range from 1 to N that are located in the ascending order. For example
#include <iostream>
#include <numeric>
#include <iterator>
int main() {
const size_t N = 20;
[Code] .....
How can it be converted using some one standard algorithm such a way that the resulted sequence would look like
1 3 5 7 9 11 13 15 17 19 20 18 16 14 12 10 8 6 4 2

I have a file that contain different content, some lines inside that file looks like that :
Time : xx:xx:xx
Time : xx:xx:xx
So, I want to grab lines that start with "Time : " and put them inside a list<string> for later use. I am using windows so I don't know if the newline character is '
' or '
' also I don't want my grabed line contain any special character.
I have this code, but didn't work well because some special characters remain inside the string.
Code:
string buf;
list<string> ls;
ifstream read("test.txt", ios_base::binary);
while(!read.eof())
{
getline(read,buf,'

In my app the user can select the pages to print by typing in a start and an end page. I think this is the standard dialog.
How can I give the user the possibility to select e.g. page "1,2,6-9" like in Word?

My code is currently reads in a string of lower case letters, identifying the occurrence of each letter.
Code:
#include <stdio.h>
#include <string.h>
int main()
{
[Code]....
My issue is that I want my code to read uppercase and special symbols. showing the occurrence of both.
Code:
else if(str[x] >= 'a' && str[x] <= 'z');
else if(str[x] >= '0' && str[x] <= '9');
However I struggle to implement it

I am a beginner and I ALWAYS have the toughest time doing I/O files. It's extremely frustrating. It "seems" it should be so simple. The program should find a code from a list of numbers. These numbers are from 0 - 9, and after each number is a space in the file. Your job is to extract a special code containing only 10 of those numbers. For the number to be part of the code, it should be divisible by 2. After extracting 10 numbers divisible by 2 for the code, write those 10 numbers to the file to form the expected code.
Input file is ("question.txt")
Output should be ("code.txt")
Should this contain a "for loop" or If/else ?
Here's what I did . .
/
// int numbers, total, counter;
ifstream inFile;
inFile.open ("question.txt");
outFile.open ("code.txt");
if (!inFile)

How can I pass ":" or " " as an argument to a process?
I start a process which takes an IP and port number (ex 222.240.224.131:80) as argument. Another character that I want to pass is white space character. Both of these characters cuts the argument string and sends only the part that leads them.

I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.

In this program what i'm doing is to search for a number when the vector is in order, and count how many times that number appears, the problem is that count how many times the number does not appear, but when its appear the program stays in an "standby mode" and the cursor does not move.
int buscarNumOrdenado (int x [MAX]) //MAX is the define {
int num,d, LimiteInferior, LimiteSuperior,mitad;
d=0;
LimiteInferior = 0;

I am attempting to write code that receives a number from the user and outputs the largest prime number underneath the user's number. There are no errors in my code, but no matter what number is imputed, the program says the largest prime number is 1. I cannot find where the issue is in the code. Here is the code I wrote:
#include <cstdlib>
#include <iostream>
#include <cmath>

I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:
Code:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int Generate() {
int r= rand();
int s= r%7;
