help me plz in C++

Plz help me to find the solution of two programs in C++:
1. program to creat array and save the values in it , and save the factorial of those values into another one (Using Array) .
2. program to creat a binary search.

Although this souds very much like homework you can try to do a search for some pseudo code. That should help greatly in the implementation of the actual application.

If you only need some language semantics google is also a great help.

Re: help me plz in C++

Ok here goes for the first question I'm going to assume that the user enters several values. Say 5. The values are stored in an array and then the factorial is computed and stored in another array.

#include <iostream>
using namespace std;

//declare factorial prototype
//no implementation is provided.
long factorial (int number); //maybe needs to be float etc.

//start of main program

void main (void)
{
 int i = 0;  //initialize a loop counter
 int user_values[5] = 0; //define input array
 long user_factorial[5] = 0; //define outut array

 for (i = 0; i < 5; i++)
 {
  cout<<"Enter some number ";
  cin>>user_values[i]; //read the user value
  cout<<newline;
  user_factorial[i] = factorial(user_values[i]); //calculate and store factorial
 }
return;
} //end main

Than should solve the problem however some remarks,
1. Assumed that only 5 values are entered -> if unknown assign dynamic
2. NO error or range checking are performed.

Hope this helps

P.S - Code may contain errors but logically it is OK

Re: help me plz in C++

AFAIK the second problem of the binary search requires that the data be sorted eiter ascending or decending. The basic concept then becomes starting at the centre determine if the desired value is above or below that. In either case move your reference point by half way and repeat until the desired information is found. Just make sure that the loop can exit if the data is indeed not in the list.

If you need some more help, just ask.
