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;}
