Hebbian and C++

Hi , i have a project in neural network (hebbian learning rule) i just want to apply it (AND gate) , I wrote a simple program but i get it to work just like it should can some one help me tracing the program .
Input pattern 1 (0,0) corresponding output -1
Input pattern 2 (0,1) corresponding output -1
Input pattern 3 (1,0) corresponding output -1
Input pattern 4 (1,1) corresponding output 1

here is the program :-

Code:

#include <iostream>
using namespace std;
int main()
{
int x[4][3],w[3],y[4][1],i,j,p;
for(i=0;i<=2;++i)
w[i]=0;
for(p=1;p<=4;++p)
x[p][0]=1;
for(p=1;p<=4;++p) {
cout<<"Enter the input Pattern number "<<p<<" : \n";
for(i=1;i<=2;++i)
cin>>x[p][i];
cout<<"Enter the corresponding output \n";
for(j=1;j<=1;++j)
cin>>y[p][j];
for(i=0;i<=2;++i)
for(j=1;j<=1;++j){
w[i]+=x[p][i]*y[p][j];
cout<<endl;

}
}
cout<<"The final weights = [ "<<w[0]<<" "<<w[1]<<" "<<w[2]<<" ]"<<endl;
clrscr();
return 0;
}

the weird thing is after enter the input patterns i get weight =[1 2 2] which supposed to be w=[1 1 1] .Thanks

Use your debugger to help you trace the program.

Good to see that you posted your code in code bbcode tags, but please indent the code properly. You provided the expected output and actual output, but you might also want to tell us the exact input that you tested.

First thanks for replying , After building and compiling the code i got no error at all I dont know if that what you mean by using your debugger

OK I will next time , Input I want to test

Code:

 { 0 0 0 , 0 1 0 , 1 0 0 , 1 1 1 }

after each number use enter , Is that clear enough ?

You did get an error, according to you, except that the error was some kind of logic error, not a compile error. A debugger can help you debug such errors. Such a tool is available with Visual Studio, and you can configure a debugger named gdb for use on some other IDEs like Code::Blocks.
