C语言 fread 以二进制形式读取文件中的数据

函数原型：
#include <stdio.h>
int fread( void *buffer, size_t size, size_t num, FILE *stream );

#include <stdio.h>
#include <string.h>

int main(void) {
	FILE *file1;
	char name[32];
	int age;
	int ret;
	
	file1 = fopen("student.txt", "rb");
	
	
	fread(name, sizeof(name), sizeof(char), file1);
	fread(&age, 1, sizeof(int), file1);
	
	printf("%s, %d\\n", name, age);
	
	fclose(file1);
	return 0;
}
