I'm trying to separate number num-by-num but according to the example it must show 501 but it shows 510.
Code:
#include <stdio.h>
#include <math.h>
int power(int base,int expo)
{
if ( expo!=1 )
return (base*power(base,expo-1));

Write a function called breakThree that will accept a 3 digit integer and returns each of the numbers individually. This function will take four paramaters. The first parameter is the three digit number to break apart. Parameters 2 through 4 are passed by reference and will be used to return each of the numbers back to main.
You should make sure that the input into the function is a 3-digit number. If it is not a three digit number the breakThree function should simply return false. If it is a three digit number the breakThree function should break the number apart, and store each of the numbers in the parameters passed by reference.
In main you should get the number from input and then output each of the numbers on a separate line.
What not to use
global variables
cin in breakThree function
cout in breakThree function
goto statements
#include <iostream>
using namespace std;
void separate(int a, int b, int c, int d);
int main(int argc, const char * argv[]) {
int num;

What is the benefit on separating the abstraction and implementation.
The below code
Code:
class FileProcessor {
public:
virtual void processFile();
};
class DocProcessor : public FileProcessor
[Code] ....
Till now it is fine. suppose DocProcessor and ExcelProcessor uses two big algorithm to process these file types then I still can have subclasses like :
class Algorithm1 : public DocProcessor
{
public:
void algorithm(); //which will be called as per the algorithm class instantiated for to process
};
[Code] ....
same for ExcelProcessor class
Here everything looks fine to me. [ I have not used the bridge pattern to separate the abstraction and implementation]. The only thing i can achieve using bridge is that the number of classes will be reduced if new class like jpgProcessor is introduced or new algorithim is introduced.
Then why it is recommended that always separate the abstraction and implementation...
I currently need separating my Prime numbers in group for my assignment. I absolutely do not know how to do this. I am able to find out if the number I used is prime and see how many prime number there are between 1-100 and then 1-1000 (168 primes) and so on. The thing that I need to do is find the number of prime numbers between 101-200, 201-300, 301-400, and so on until 901-100 and have it show on screen. Here is the exact assignment that I’m supposed to find out:
Assignment:
Write a C++ program to calculate and display the number of primes from 1 to 100,000, separated in groups of 100, 10 groups per line. To be more precise, on the first line of output, display the number of primes between 1 and 100, 101 and 200, etc., up to 901 to 1000. Then display the average primes per group. For example, there are 168 primes from 1 to 1000, so the average number of primes per group of 100 (or percentage) is 16.8. Then repeat the process for the groups of 100 between 1001 to 1100, 1101 to 1200, etc., for all groups of 1000 all the way up to 100,000. Your results should be as presented below, under testing.
Testing:
The output of your program should be the following, according to my calculations. Each group (g1, g2, etc.) is the number of primes in a group of 100 numbers. For example in line 1, g1 is the group from 1 to 100, g2 is the group 101 to 200, etc. For line 2, g1 is the group 1001 to 1100, g2 is 1101 to 1200, and g10 is the group from 1901 to 2000.
g1 g2 g3 g4 g5 g6 g7 g8 g9 g10 Average Primes
----------------------------------------------------------------
25 21 16 16 17 14 16 14 15 14 16.8 for 1 to 1000
16 12 15 11 17 12 15 12 12 13 13.5 for 1001 to 2000
14 10 15 15 10 11 15 14 12 11 12.7 for 2001 to 3000
12 10 11 15 11 14 13 12 11 11 12.0 for 3001 to 4000

8 11 8 8 7 9 8 10 10 8 8.7 for 99001 to 100000
Total number of primes from 1 to 100000: 9592
Average primes per 1000: 95.92
Percentage of primes from 1 to 100000: 9.59

using namespace std;
bool isPrime(long candidate);

I am trying to separate out particular sets of routines into a separate implentation and header file which can be compiled independently to the main program such that the program source consists of a file called customers.h, customers.cpp, and exercise_1_5.cpp

customers.h should contain the definition of the customer structure and the declaration of print_customers.
customers.cpp should contain the implementation (or definition) for print_customers.
exercise_1_5.cpp should contain an include of customers.h and the main program.
This is my original code from a single .cpp file
#include<iostream>
#include<string>
using namespace std;

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;
LimiteSuperior = MAX-1;

I'm taking a C++ computer science course right now, and one of the questions on my latest assignment is this:
"A partition of an integer n is a way of writing n as a sum of positive integers. For example, for n=7, a partition is 1+1+5. Write a program that finds all the partitions of an integer n using r integers. For example, all the partitions of n=7 using r=3 integers are 1+1+5, 1+2+4, 1+3+3, 2+2+3."
I've been struggling with this problem for a couple days now, and how to do it. I understand I need a recursive function to grab variables, and probably an array or vector to store them, but where to begin.
I've been reading documents on partition generating and the concept still eludes me, and any other questions on here or other programming sites using partitions don't seem to have a constraint on them.
I have to write a program that will ask you to put in a number between 0 and 9 and multiply it by pi. If the number put in is between 0 and 9 then pi is multiplied but if it isnt between 0 or 9, it will say the number is not between 0 and 9 and asks you to put it in again and will repeat until a number between 0 and 9 is put in.
I have got the program working to the extent that it the number is between 0 and 9 it will multiply it by pi but if its not between 0 and 9 it will say the number is not between 0 and 9 and ask to put in a new number.
I can't work out how to get the program to repeat itself if the number entered isnt between 0 and 9.
I have enclosed the code below .....
I am working with C++ in Visual Studio. It's my first semester doing anything like this ever. Still, I am embarrassed that I am having trouble with this simple "coin flipping" program. The user tells the program how many times to "flip the coin" & then the program tells the user the results of each flip. You'll see I am randomly generating a 1 or a 2 within the function coinFlip to represent heads or tails. However, the problem is that if the user wants more than one coin flip, the "random" number stays the same for all of them, resulting in all heads or all tails. I am thinking this is an issue with the for loop that I have within the function coinFlip.

Try not to make too much fun of me for my logic, but I'm having trouble with this. I am trying to make it so the program takes a 1 dimensional array and a 2 dimensional array, and checks to see what row in the 2 dimensional array is the closest to the 1D array.
To compute the value of the 1D array you take the first row first element in the 2D array, and the first element in the 1D array, subtract and the absolute value.
Example: | 4 - 3 | = 1;
1Darray = 1.
Full 1 Dimensional Array:
3 1 6 9
Full 2 Dimensional Array:
4 9 1 5
6 1 7 3
0 8 2 6
To compute the value of the first row in the 2D array,
| 4 - 3 | + | 9 - 1 | + | 1 - 6 | + | 5 - 9 | = 18.
| 6 - 3 | + | 1 - 1 | + | 7 - 6 | + | 3 - 9 | = 10.
| 0 - 3 | + | 8 - 1 | + | 2 - 6 | + | 6 - 9 | = 17.
Thus row 1 being the closest row to the 1 dimensional array.
The code I've written so far seems to be going down the right path. Have a look below...
Code:
int i,j,tempRow,tempTotal = 0,firEle,cloRow;
firEle = abs( x[0][0] - y[0] );
for( i = 0; i < size; i++ ) {
tempRow = 0;
for( j = 0; j < size; j++ ) {
tempRow += abs( x[i][j] - y[j] );
[Code] ....
The whole temp part is kind of confusing myself. What I'm thinking is that I can add all row values up using
Code: tempRow += abs( x[i][j] - y[j] ); , then I need to compare that value to see if it is close to the "firEle" which is value I need to get closest to.
