Linear search

[littlegirl]

hi guys can some one help me here
i have to accept a number
and preform a linear search for the numbers

and if its not one of the number it has to say its invalid
#include <iostream>
using namespace std;
int searchlist (int[],int,int);
int main()
{
const int Num_Account = 18;
char Account[Num_Account]=
{"5658845, 4520125", "7895122, 8777541",
"8451277, 1302850",
"8080152, 4562555", "5552012, 5050552",
"7825877, 1250255",
"1005231, 6545231", "3852085, 7576651",
"7881200, 4581002" };

cout << "enter Number\n";
cin >> num;

int searchlist(int list [],int num,int value)
{
int index = 0;
int position = -1;
bool found = false;

while (index < num &&!found)
{
if (list == value)
{
found = true;
position = index;
}
index++;
}

return 0;
}

Try first of all to move the definition of the 'searchlist' function to
/above/ the 'main' function: C++ does not support direct nesting of
function definitions.

When you've moved the definition, remove the declaration of 'searchlist'
that you now have after your 'using' directive, and in general, avoid
declaring functions that you define later on.

In 'main' you need to call 'searchlist', and present the result of that
call.

You promised to return an int. Remember? There is no way for the caller to
determine what happened.

An int works fine, but the more modern way is to return a bool, it has
better self-documenting properties than an int.
return 0;
}
