C语言读取文件时如何统计函数个数

使用fopen函数打开文件，使用fgetc()一个字符一个字符的读取，然后计数统计就可以啦，fget()从文件指针stream指向的文件中读取一个字符，读取一个字节后，光标位置后移一个字节，这个函数的返回值，是返回所读取的一个字节。如果读到文件末尾或者读取出错时返回EOF。

#includestdio.h

int main()

{

FILE *fp;

char filename[50];

int num=0;

printf("输入一个文件名: ");

gets(filename);

if((fp=fopen(filename,"r"))==NULL)

{

printf("文件打开失败..\n");

return ;

}

while(!feof(fp))fgetc(fp)num++;

printf("%s 文件中共有字符个数: %d\n",filename,num);

fclose(fp);

return ;

用C语言编写一个简单的图书管理小程序

源代码如下：

#includeiostream

#includeiomanip

#includestring

#includefstream

#includestdio.h

using namespace std;

const   int   maxb=10000;   //最多的图书

class   book//图书类

{

int   tag;   //删除标记1:已删0:未删

int   number;   //isbn书号

char   name[20];   //书名

char author[10]; //主编

char number2[10];//版次

char position[20];//出版社

char time[20];//出版年

void   addbook(int n,char *na,char *au,char *n2,char *da,char *ti,int pr)   //增加图书  

{

tag=0;

number=n;

price=pr;

strcpy(name,na);

strcpy(author,au);

strcpy(number2,n2);

strcpy(position,da);

strcpy(time,ti);

onshelf=1;

}  

扩展资料

1、源程序中，很多符号都是成对匹配出现的，为避免遗漏必须配对使用的符号。

2、用花括号括起来的部分，但从程序结构清晰，便于阅读、理解、维护的角度出发，建议在书写程序时应遵循以下规则，以养成良好的编程习惯。

3、一个说明或一条语句占一行，与该结构开始处的左花括号对齐。
