hello 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
but i keep getting and error for to many int

#include <iostream>
using namespace std;
int searchlist (int[],int,int);
int main()
{
const int Num_Account = 18;
// Error here 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 [index] == value)
{
found = true;
position = index;
}
index++;
}

return 0;
}

char is most likely given 1 byte by your compiler. 1 byte is capable of holding numbers max 0..255. Obviously 5658845 is slightly bigger than that. You should consider numeric types that provide more space.

now i get this error C:\Program Files\Microsoft Visual Studio\MyProjects : error C2109: subscript requires array or pointer type



#include <iostream>
using namespace std;
int searchlist (int[],int,int);
int main()
{
double list,
value,
num;
const int Num_Account = 255;
[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)
{
// Error if (list [index] == value)
{
found = true;
position = index;
}
index++;
}

return 0;
}

& why nobody in this forum programs in java?? i'd also choose a pink nick, put a sexy avatar & ask u solve all my assignments!!

[Silver]

imjustagirl, what is this?

const int Num_Account = 255;
[Num_Account]=
{5658845, 4520125, 7895122, 8777541, 8451277, 1302850,
8080152, 4562555, 5552012, 5050552, 7825877, 1250255,
1005231, 6545231, 3852085, 7576651, 7881200, 4581002; };

moonlight, give it a try Seriously. I might even learn Java!

Silver, too late, i finished the class.vsyu jizn' opazdivayu!((

[imjustagirl]

the account numbers that have to be searched. any number can be typed in but if that number is not on the list you get an invalid number error. those are the numbers that will display number valid.
{5658845, 4520125, 7895122, 8777541, 8451277, 1302850,
8080152, 4562555, 5552012, 5050552, 7825877, 1250255,
1005231, 6545231, 3852085, 7576651, 7881200, 4581002; };

imjustagirl, don't you think you must supply a name and a type for your array before filling it with values?

[Num_Account]=

what is this array's name? what is its type?

[imjustagirl]

double num;
int 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 [index] == value)
{
found = true;
position = index;
}
index++;
}

return 0;
}


i guess array name could be Account

[Silver]

imjustagirl, static array size cannot be variable (Num_Account), it should be const.

[imjustagirl]

but i keep getting an error
c:\program files\microsoft visual studio\myprojects : error C2065: 'i' : undeclared identifier



#include <iostream>
using namespace std;
int searchlist (double [],int,double);
const int Num_Account = 18;
int main()
{
double num;
double 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;

if(searchlist(Account,Num_Account,num))
cout << "Account Exists\n";
else
cout << "Account does not Exist\n";

return 0;
}

int searchlist(double list [],int num,double value)
{
for(i=0;i<num;i++)
if (list [i] == value)
return 1;
else
return 0;
}

Because you did'nt declare the i variable befire or in the for loop

...
for(int i=0;i<num;i++)
...

And by the way, you got a bug in your code. It will check only first array element and quit searching. Here is the correct verstion

...

for(int i=0;i<num;i++)
if (list [i] == value) return 1;

return 0;

...

BTW, use bool for boolean type if you are using C++.
