C :: Take Integer And Splits It Into Individual Numbers
Oct 9, 2013
I'm supposed to write a code that takes an integer and splits it into individual numbers e.g. 234 becomes 2 3 4 .the individual numbers are then passed on to a function that accepts only one number at a time
All i could think of was this,but its a very bad method coz i dont know how long a number would be inputed into "Angle_in_degree"
Code:
int Angle_in_degree,a,b,c
c= Angle_in_degree %10;
b=Angle_in_degree/10 %10;
a=Angle_in_degree/100 % 10;
function(a);
function(b);
function(c);

Write a full C++ program that inputs three-digit integer, separates the integer into its individual digits and prints the digits separated from one another. For example, if the user types 549, the program should print;
5 4 9

In my program, I am fed a string that contains integers such as Code: *str = "45678" and my program is simply supposed to read the number in and store each given number in a separate spot in an integer array. So basically, when my program has finished running it should be stored like:
Code:
arr[0] = 4
arr[1] = 5
arr[2] = 6
arr[3] = 7
arr[4] = 8
The way I have been attempting to do this was just copying it to the array like so:
Code:
arr = malloc(sizeof(int) *(strlen(str));
for (i=0; i<strlen(str); i++) {
a->digits[i] = str[i];
}
however, this just seems to return an impossibly high garbage value when I do. I'm assuming the way I'm trying to store it is 'illegal', but I cant seem to find online a proper way to do it.

My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";
[Code] ....

I am writing trying to store a list of numbers into an integer as bits. So far I have this:
n=n & 0x0f
integer = integer<<2
integer = integer | n;
convert(integer));
I want it to store the integers as bits so that I am move them over and store them farther down the row as more numbers are added, but instead each new number is being added to the previous and I'm just getting a larger integer. Is this even a feasible way to store integers within an integer?

Alexandra has some distinct integer numbers a1,a2...an.
Count number of pairs (i,j) such that:
1≤ i ≤ n
1≤ j ≤ n
ai < aj
Input
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. The first line of each test case contains a single integer n denoting the number of numbers Alexandra has. The second line contains n space-separated distinct integers a1, a2, ..., an denoting these numbers.
Output
For each test case, output a single line containing number of pairs for corresponding test case.
Constraints
1 ≤ T ≤ 4
1 ≤ n ≤ 100000
0 ≤ ai ≤ 109
All the ai are distinct
Example
2
2
2 1
3
3 1 2
Output:
1
3
Explanation
Case 1: Only one such pair: (2,1)
Case 2: 3 possible pairs: (2,1), (2,3), (3,1)
as I understand the problem is just counting how many Ai's are 1 <= Ai <= N and then apply ((R*(R-1))/2), R is the count of valid Ai's
My actual code is
#include <stdio.h>
using namespace std;
#ifndef ONLINE_JUDGE
#define getNumber getchar()
#define getString getchar()
[Code] ....

Write a C program that sorts an unsorted array of 5 integer numbers in ascending order by swapping numbers repeatedly. Specifically, first prompt the user to input 5 numbers and store the numbers in an array. Then, if the numbers in the array are not in ascending order, ask the user to provide the indices of two numbers in the array that the user wants to swap. If the user does not enter valid indices (i.e., outside 0 to4), then re-prompt the user to enter new indices. Continue prompting the user to provide indices of numbers to swap until the array becomes sorted in ascending order. Finally, when the array becomes sorted, the program should print "The array is now sorted in ascending order".
Implementation Requirements
Use the #define directive to define the size of the array.
Implement a function called "checkArrayOrder" to check whether an array is in ascending order or not. The prototype of the function is
"intcheckArrayOrder(int arr[], int size);". The function should return
1 if the array passed to the function is in ascending order0 if the array passed to the function is not in ascending order
Define the function prototype in your program.
Implement a function called "swap", whose prototype is "int swap(int arr[], int size, int i, int j);" which swaps the numbers in positions "i" and "j" of the array passed to the function and returns
1 if the indices"i" and "j" are within bounds (i.e., between 0 and 4) and the swap operation is performed correctly.
0 if the indices"i" and "j" are outside bounds so that the swap operation cannot be performed.
Define the function prototype in your program.
Use the function "checkArrayOrder" whenever your program needs to check whether an array is in ascending order or not; and the function "swap" to swap the numbers the user specifies (Note that, you should check whether the user provided indices are valid inside the function "swap" and not inside "main").
here is my code so far
Code:
#define ARRAY_SIZE 5
void main()
{
int i, array[ARRAY_SIZE];
printf("Enter %d numbers
", ARRAY_SIZE);
for(i=0; i<ARRAY_SIZE; ++i)
scanf("%d", &array[i]);
[Code] .....
I'm just not sure how to proceed. I'm not really sure how to progress the checkArrayOrder function to the swap function (in the if statement).

Write a program asks the user for a positive integer value and then prints out all perfect numbers from 1 to that positive integer. I have been trying for some time, i found a way to check if its a perfect number or not but could not find a way to prints out all perfect numbers from 1 to that positive integer. I am here so far.
#include<iostream>
#include<iomanip>
using namespace std;
int main(){
int n,i=1,sum=0;
cout<<"Enter a number: ";

Why this class doesn't work for Subtraction, Division and Square Root. When I try to get results for Subtraction, it output right answer, but with any trash. And When I try to get answer for Division and Square Root, it just brakes and don't output anything. For Addition and Multiplication class work correctly.

I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
Code:
#include <iostream>
using namespace std;
void resize(int *[], int);
int main() {
int *listDyn;
int size=2;

void main() {
FILE *fp;
fp=fopen("read.txt","r");
double *read_feature = new double*[3];

I haven't actually learned how to use arrays yet but I know the basic principle of it and decided to try and implement one to improve my code. I'm sure the thing is a bug ridden mess but I would particularly like to point your attention to the function sortDenomination(). Is what I am trying to do in the loop possible?
The reason why I want to do it this way and not with if statements for each denomination is because I can then easily apply this to the second part of the assignment which sees us split a double into dollars and cents and then process each separately. All I would have to differ for each is change the money_loop variable to include the last two denominations in the array.
Code:
#include <stdio.h>
/*Reads cents input from the user.*/
void getCents(int &read_cents) {
printf("Please enter the amount of cents between 5-95:

I'm a C beginner. I have questions, let say if I have a structure of message containing of Id, Length, and 3 bytes of data, and I want to manually saved in individual bits of data, how can I do that? I confused on how to use typedef struct and union. Below is the sample code:
typedef struct {
uint8_t Id;
uint8_t Length;
uint8_t DataField[3];
}AA;
[Code] .....
By the way, the DataField is declared as above. It's not necessary for a data to be 24 bits. It can be bit 0 - bit 8, it can be bit 10 - bit 15 and so on. So, for each case, I want to ignore the other bits.

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;

However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.

i am developing a multi-lingual application allowing users to change language as well as keyboard layouts (through combobox). I am able to change the culture of application successfully but i'm unable to change the individual keyboard layouts e.g. for English (United States), im unable to change layouts from QWERTY (default) to Dvorak - Left hand etc... I don't just want to change the input language, i was also want to be able to type in different keyboards. Here's the code (e.g. for English language), the imports etc are added already..
CultureInfo TypeOfLanguage = CultureInfo.CreateSpecificCulture("en-US");
System.Threading.Thread.CurrentThread.CurrentCulture = TypeOfLanguage;
InputLanguage l = InputLanguage.FromCulture(TypeOfLanguage);
InputLanguage.CurrentInputLanguage = l;

I have code working, but that is largely because a vector that I am using as part of a structure that is the first of two elements of a MAP (with the second being an integer that is assigned later) is serving in its original, purely vector form, to fill out a set of selections on a DOS screen (option 1, 2, 3, etc.).
I do use the MAP, because it is a simple means of referencing the integer value using a word that is part of the structure, and is probably appropriate, saving me a search through the vector of words and calling up the value at the same location in the vector of words in a vector of corresponding numerical values. I DO feel that what I'm doing to produce the selection list is something of a "cheat" because I do not know how to access the same data within the structure component of the MAP by simply using a similar numerical reference (e.g. "MAP[1].structure.word", or would that be "MAP.structure.word[1]" ????) to print out the words in the structure in the map as choices on the screen.
I don't want to change or expand the contents of the map, just access and print each one in a simple loop with a number from the loop counter to the left of each word.

typedef struct{

I dont even know where to start. I spend the last 7h infront of my computer and i'm so frustrated cause my professor gave us no information what so ever. At the moment its more of a trial and error process than anything else.
How would i set the color of an individual pixel for examplel or how would i save the file ?

I am currently working with win32 API , for image processing, one of the windows function returns RGBA ( colors ) as unsigned int , I then split it into individual bytes by creating a union ,
Code:
union colour {
unsigned int value;
unsigned char RGBA[4];
}
to spit the int into individual bytes, my Question is there a better or my convenient way of doing this.

In the program I'm writing, I'm creating a linked list of students with individual data read from a file. At the moment, I have written two functions to accomplish this; one that creates a student node and fills it from a line file, and a second that calls on the first to create a linked list. It seems to work fine except for one thing; It seems that EOF is being reached first, but the function continues on anyways? Here is my code so far...
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct student
// Declaring student structure globally.
[Code] .....
And here is what the input file would look like...
Thui Bhu, 100, 90, 80, 100, 89, 99, 88
Ariana B. Smith, 90, 90, 100, 100, 99, 100, 95
Emily Gonzales, 100, 90, 100, 70, 78, 78, 80
Jennifer L, 80, 90, 90, 100, 89, 99, 85
Maria Jones, 65, 72, 77, 68, 62, 70, 65
Bill Gates, 60, 54, 38, 62, 65, 60, 50
Escobar Morris, 83, 77, 88, 76, 79, 72, 76
Anne Latner, 80, 80, 85, 95, 90, 95, 98
John Doe, 45, 87, 88, 89, 67, 96, 79
And here is what the output is...

EOF in create_record
Thui Bhu: 100 90 80 100 89 99 88
Ariana B. Smith: 90 90 100 100 99 100 95
Emily Gonzales: 100 90 100 70 78 78 80
Jennifer L: 80 90 90 100 89 99 85

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);

Output of the code is
3 J JD
k
but I want
3
J
