小程序分享：str1和str2对应的串相等， 但是a.txt和b.txt不相同。

#include <iostream>
using namespace std;
 
int main()
{
	char str1[100] = "ab\0cdddddddddd";
	cout << str1 << endl;
 
	FILE *fa = fopen("a.txt", "wb");
	fwrite(str1, sizeof(str1), 1, fa);
	fclose(fa);
 
	
	char str2[100] = "ab";
	cout << str2 << endl;
 
	FILE *fb = fopen("b.txt", "wb");
	fwrite(str2, sizeof(str2), 1, fb);
	fclose(fb);
 
 
	if(0 == strcmp(str1, str2))
	{
		cout << "yes" << endl;
	}
	else
	{
		cout << "no" << endl;
	}
 
	return 0;
}
