Let's write a C program to open a file from a hard disk whose name is entered by a user and to display its contents on the screen. Opening a file means we bring the file contents from disk to RAM to perform operations (read/modify/append a file) on it. The file must be present ...
int fprintf(FILE *stream, const char *format, ...); 用于向文件写入格式化数据。它是 printf() 函数的文件操作版本,允许将格式化的输出写入指定的文件流中,而不是标准输出。 函数原型 int fprintf(FILE *stream, const char *format, ...); stream:指向 FILE 对象的指针,该对象标识了将要进行写操作的流...
int fread(void *buf, int read_size, int read_count, FILE *fp); 其中buf为任意已经分配的内存空间,read_size为每次读取的空间大小,read_count为读取read_size大小空间的次数,也就是fread是分多次读取文件,每次读read_size个字节,反复读取read_count次,所以buf的大小至少为read_size*read_count字节,而且fread...
voidreadfile(string filename){ifstreamfin(filename);string s;if(!fin)//检测文件输入是否正常{cout<<"文件不能打开"<<endl;}else{while(fin>>s){cout<<s<<' ';}cout<<endl;}fin.close();} C语言打开文件读取数据 C语言中要打开一个文件,需要调用fopen函数。 一、函数名:fopen 二、头文件:stdio...
