C Program crashes after compiling without error

Hello there.

I'm heaving trouble with a C Program that I'm writing to simulate a Multi-Layer Neural Network. It compiles without any issues, but when I run it, it crashes instantanously. I would be very thankful if anyone could give me a hint. The code is below:

/* Multi layer network to classification of data */

#include
#include
#include
#include
#include

#define MAX_SIZE 1000
#define LRATE 1e-5
#define ERR_LIMIT 1e-3
#define MAX_TIME 55

#define INPUTS 2
#define NEURONSLAYER1 4
#define NEURONSLAYER2 3
#define NEURONSLAYER3 1

#define sqr(x) ((x) * (x))

float max1,max2;

void mapping1(float in[][INPUTS+1], int n) {

int i, j;

if(in[0][1]<0) max1 = (in[0][1])*(-1.0);
else max1=in[0][1];

printf("%f
", max1);

for(i=1;i<n-1;i++)
{
if(in[i][1]>max1 && in[i][1] < 0)max1 = in[i][1]*(-1.0);
if(in[i][1]>max1 && in[i][1] >= 0)max1 = in[i][1];
}

printf("%f
", max1);

for(j=0;jmax2 && in[i][2] < 0)max2 = in[i][2]*(-1.0);
if(in[i][2]>max2 && in[i][2] >= 0)max2 = in[i][2];
}

printf("%f
", max2);

for(j=0;j 0) printf("+1
");
if(OLayerOut[m-1] <= 0) printf("-1
");
}

//Training Routine
else
{
//Read Training
read = scanf("%f,%f,%d", &Input[n][1], &Input[n][2], &ExpectedOut[n]);
n++;
//Check condition for initialization of training
if(Input[n-1][1] == 0 && Input[n-1][2] == 0 && ExpectedOut[n-1] == 0)
{

mapping1(Input,n);
c = max1;
mapping2(Input,n);
d = max2;

//Begin Training
do{
//If the program takes too long, break
if((time(NULL) - start) > MAX_TIME)
{
flag = 1;
break;
}

//If the set is over but the training isn't, restart
if(l == (n-1))
{
l=0;
error_sum = 0;
}

//Initiates over the training set
for(l=0;l ERR_LIMIT );
flag = 1;
}
}
}while(read != EOF);

return 0;
}



Comments

  • I have no good debugger for this so I replaced some of your
    // comment....
    with printf("comment....
    ");
    and got this:

    Timer variable
    Initialize weights

    before the crash


    Have you tested any of the neural net programs by karsten Kutza?
    They are in C and works well with my compiler (Borland 5.5)
  • thanks it works
