哪位大神帮忙看下这段程序？

Question

read_num_class_data( const char* filename, int var_count,
CvMat** data, CvMat** responses )
{
const int M = 1024;
FILE* f = fopen( filename, "rt" );
CvMemStorage* storage;
CvSeq* seq;
char buf[M+2];
float* el_ptr;
CvSeqReader reader;
int j, j;

if( !f )
    return 0;

el_ptr = new float[var_count+1];
storage = cvCreateMemStorage();
seq = cvCreateSeq( 0, sizeof(*seq), (var_count+1)*sizeof(float), storage );

for(;;)
{
    char* ptr;
    if( !fgets( buf, M, f ) || !strchr( buf, ',' ) )
        break;
    //el_ptr[0] = buf[0];
    //ptr = buf+2;
    ptr = buf;
    for( j = 0; j <= var_count; j++ )
    {
        int n = 0;
        sscanf( ptr, "%f%n", el_ptr + j, &n );
        ptr += n + 1;
    }
    if( j <= var_count )
        break;
    cvSeqPush( seq, el_ptr );
}
fclose(f);

看怎么看都行，问题是你的问题是什么，你什么都不说没人愿意看
