What are the file reading and writing functions in C language?

对文件的读和写是最常用的文件操作。

在C语言中提供了多种文件读写的函数:

字符读写函数  :fgetc和fputc

字符串读写函数:fgets和fputs

数据块读写函数:freed和fwrite

格式化读写函数:fscanf和fprinf

下面分别予以介绍。使用以上函数都要求包含头文件stdio.h。

示例:

#include<stdio.h>
main(){
    FILE *fp;
    char ch;
    if((fp=fopen("d:\\jrzh\\example\\c1.txt","rt"))==NULL){
        printf("\nCannot open file strike any key exit!");
        getch();
        exit(1);
    }
    ch=fgetc(fp);
    while(ch!=EOF){
        putchar(ch);
        ch=fgetc(fp);
    }
    fclose(fp);
}
