读文件

//读文件
int main(){
    char * path ="";
    //打开路径
    FILE *fp =fopen(path, "r");

    char buff[50];
    while (fgets(buff, 50, fp)) {
        printf("%s",buff);
    }

    fclose(fp);
    return 0;
}

写文件

//写文件
int main(){
    char * path ="";
    FILE *fp =fopen(path, "w");
    if (fp==NULL) {
        printf("failed ....")
    }
    char *text ="test write file";
    fputs(text, fp);
    fclose(fp);
    return 0;
}

读写二进制文件

int main() {
    char * read_path = "G:\\0_preClass\\NDK\\class\\Ls_C5\\files\\LogViewPro.exe";
    char * write_path = "G:\\0_preClass\\NDK\\class\\Ls_C5\\files\\LogViewPro_write.exe";

    //read
    FILE * read_fp = fopen(read_path, "rb");
    //write
    FILE * write_fp = fopen(write_path, "wb");
    char buff[50];
    int len = 0;
    while ((len = fread(buff, sizeof(char), 50, read_fp)) != 0)
    {
        fwrite(buff, sizeof(char), len, write_fp);
    }
    fclose(read_fp);
    fclose(write_fp);
    system("pause");
    return 0;
}
