问身边的人也都改不掉这些错误。。只能到这里求救了！

C语言vc6环境。关于图像算术编码的。这是其中那个关于解码的头文件，求大神改错！
/*ARITHMETIC DECODING ALGORITHM.*/
#pragma once
#include"accode.h"
/*CURRENT STATE OF THE DECODING.*/
static code_value value;
static code_value low,high; //本行有错
/*START DECODING A STREAM OF SYMBOL.*/
start_decoding()
{
int i;
value=0;
for(i=1;i<=Code_value_bits;i++)
{
value=2*value+input_bit(); //本行有错
}
low=0;
high=Top_value;
return 0;
}
/*DECODE THE NEXT SYMBOL.*/
int decode_symbol(cum_freq)
int cum_freq[]; //本行有错。。还报了两个错
{
