我有两个子程序：
// code 1:
short con_sig_model( unsigned char **Fc, short i, short j,
    short x_start, short y_start, short x_end, short y_end, unsigned short subband)
{  
    short h,v,d,hv,temp;
    h=0; // h = 0,1,2
    v=0; // v = 0,1,2
    d=0; // d = 0,1,2,3,4

    if(((j-1)>=x_start)&&Fc[i][j-1]) h++;
    if(((j+1)<x_end)&&Fc[i][j+1]) h++;
    if(((i-1)>=y_start)&&Fc[i-1][j]) v++;
    if(((i+1)<y_end)&&Fc[i+1][j]) v++;
    if(((i-1)>=y_start)&&((j-1)>=x_start)&&Fc[i-1][j-1]) d++;
    if(((i-1)>=y_start)&&((j+1)<x_end)&&Fc[i-1][j+1]) d++;
    if(((i+1)<y_end)&&((j-1)>=x_start)&&Fc[i+1][j-1]) d++;
    if(((i+1)<y_end)&&((j+1)<x_end)&&Fc[i+1][j+1]) d++;

    if(subband==3)
    {
        hv=v+h;
        if(d>=3)       return 8;
        else if(d==2){
            if(hv>=1)  return 7;
            else       return 6;
        }
        else { // d = 1,0
            if(hv>=2)  return 2 + d*3;
            return hv + d*3;
        }
    }
    else // subband = 0,1,2
    {
        if(subband==1) { // subband = 1,2
          temp=h; h=v; v=temp;
        }

        if(h==2)       return 8;
        else if(h==1){
            if(v>=1)    return 7;
            else {
                if(d>=1) return 6;
                else     return 5;
            }
        }
        else { // (h==0)
            if( v>0 ) return v+2;
            else { // (v==0)
                return (d>=2) ? 2: d;
            }
        }
    }   
}
// code 2:
short con_sig_model(
    unsigned char **Fc,
    short i,
    short j,
    short x_start,
    short y_start,
    short x_end,
    short y_end,
    unsigned short subband)
{  short h,v,d,hv,temp;
    h=0;
    v=0;
    d=0;

    if(((j-1)>=x_start)&&Fc[i][j-1]) h++;
    if(((j+1)<x_end)&&Fc[i][j+1]) h++;
    if(((i-1)>=y_start)&&Fc[i-1][j]) v++;
    if(((i+1)<y_end)&&Fc[i+1][j]) v++;
    if(((i-1)>=y_start)&&((j-1)>=x_start)&&Fc[i-1][j-1]) d++;
    if(((i-1)>=y_start)&&((j+1)<x_end)&&Fc[i-1][j+1]) d++;
    if(((i+1)<y_end)&&((j-1)>=x_start)&&Fc[i+1][j-1]) d++;
    if(((i+1)<y_end)&&((j+1)<x_end)&&Fc[i+1][j+1]) d++;

    if(subband==3){
      hv=v+h;
      if(d>=3)       return 8;
      if(d==2){
            if(hv>=1)  return 7;
            else       return 6;
        }
      if(d==1){
            if(hv>=2)  return 5;
            if(hv==1)  return 4;
            if(!hv)    return 3;
        }
      if(!d){
            if(hv>=2)  return 2;
            if(hv==1)  return 1;
            if(!hv)    return 0;
        }
     }
    else{//0,2  
      if(subband==1){ //1
          temp=h;
          h=v;
          v=temp;
        }
      if(h==2)       return 8;
      if(h==1){
          if(v>=1)    return 7;
          else{
              if(d>=1) return 6;
              else     return 5;
            }
        }
      if(h==0){
          if(v==2)    return 4;
          if(v==1)    return 3;
          if(v==0){
              if(d>=2) return 2;
              if(d==1) return 1;
              if(d==0) return 0;
            }
        }
     }
 return 0;//avoid compiler warning!      
 }
 
我用什么方法来验证上述两个代码的功能是否一致呢  ？？

你自己编一个小主程序啊

思路呢 ？
