求助统计字数的小程序

[亚洲来客]

本人想编一个程序，用来统计一篇短文的字数

汉字、英文（不分大小写）、数字共三种符号

入口地址是 一个文本文件名字 比如story.txt。然后得到

汉字：？个
英文：？个
数字：？个

求助大家：
读文件用什么好，getline（），还是read（）。。。？

能读汉字的类有哪些？

如何统计数量？

\Program Files\DEV-CPP\Statistics.cpp C:\Program Files\DEV-CPP\C stream: No such file or directory.

int main(int argc, char* argv[])
{
   // const char* content = "1一A2二B3三C4四D五EF";
   
   ifstream ifs("static.txt");
    TCount count;
    string line;
    while(getline(ifs, line))  
       {
	   CountString(line, line.length(), count);
       }
    printf("chinese : %d\nenglish : %d\nnumeric : %d\n", count.chinese,count.english, count.numeric);
            
    system("pause");
       ifs.close();
    return 0;
}

我把你的code改了一下结果编译出现上述故障，请问是为什么?

int main(int argc, char* argv[])
{
   // const char* content = "1一A2二B3三C4四D五EF";
   
    ifstream ifs("statistics1.txt");
    TCount count;
    string line;    
    while(getline(ifs, line))  
       {
	   CountString(line, line.length(), count);
        }          
    printf("chinese : %d\nenglish : %d\nnumeric : %d\n", 
           count.chinese, count.english, count.numeric);           
    system("pause");
    	ifs.close();
    return 0;
}

读文件用fscanf 就行了

通过ascii码的值来判断 是那个字符

记住 单个汉字占两个字符

这种方法只能统计ascii编码的文件

Unicode编码的不适用

[高性能架构探索]

读文件当然用 ReadFile了

[chainyu]

我弄了个统计日文字符的
::GetWindowTextW(pWnd->m_hWnd, lpString, 500000); //读取到文本框内容

[亚洲来客]

ReadFile是VC自带的
fscanf是c语言自带的

哪个用途广一点？

.txt文件里汉字和unicode转换是否遵循国家标准？哪个标准？

[samson_fan]

你的编译不能通过吧，我的代码是
void CountString(const char* content, int length, TCount& count)

你的 line 是 string 类型，应该这样才行吧
CountString(line.c_str(), line.length(), count);

抛砖引玉，供lz参考

#include <memory.h>
#include <string.h>
#include <process.h>

struct TCount
{
	int chinese;
	int english;
	int numeric;
};

#define BYTE unsigned char
#define WORD unsigned short
#define ByteToWord(h,l) ((BYTE)h<<8|(BYTE)l)
void CountString(const char* content, int length, TCount& count)
{
	memset(&count, 0, sizeof(count));

	int i;
	WORD tmp;
	for ( i=0; i<length; i++ )
	{
		if ( 'A' <= content[i] && content[i] <= 'Z' 
			|| 'a' <= content[i] && content[i] <= 'z' )
		{
			++count.english;
		}
		else if ( '0' <= content[i] && content[i] <= '9' )
		{
			++count.numeric;
		}
		else if ( i + 1 < length )
		{
			tmp = ByteToWord(content[i], content[i+1]);
			if ( 0x8140 <= tmp && tmp <= 0xFEFE )
			{
				++count.chinese;
				++i;
			}
		}
	}
}

int _tmain(int argc, _TCHAR* argv[])
{
	const char* content = "1一A2二B3三C4四D五EF";

	TCount count;
	CountString(content, strlen(content), count);
	printf("chinese : %d\nenglish : %d\nnumeric : %d\n", count.chinese, count.english, count.numeric);
	system("pause");
	return 0;
}

附个中文编码

再供lz参考

int main(int argc, char* argv[])
{
    //const char* content = "1一A2二B3三C4四D五EF";

	// 初始化文件
	ofstream ofs("statistics1.txt");
	if ( !ofs.bad() )
	{
		ofs << "1一A2二B3三C4四D五EF" << endl;
		ofs.close();
	}

	// 读文件数据并统计数据
	ifstream ifs("statistics1.txt");
	if ( !ifs.bad() )
	{
		TCount count, line_count;
		memset(&count, 0, sizeof(count));
		string line;
		while( getline(ifs, line) )
		{
			CountString(line.c_str(), line.length(), line_count);
			count.add(line_count);
		}
		printf("chinese : %d\nenglish : %d\nnumeric : %d\n", count.chinese, count.english, count.numeric);
		ifs.close();
	}
	system("pause");
    return 0;
}

你新的main（）内
新增了
count.add(line_count);
我的dev 5.0编译通不过


报错：
