C++头文件怎么编写

就是格式。。。还有怎么再主程序中调用，本人新手，勿喷...

Answer 1

给你一个头文件的例子,#ifndef __RIJNDAEL_ALG_H
#define __RIJNDAEL_ALG_H#define MAXKC (256/32)
#define MAXROUNDS 14typedef unsigned char word8;
typedef unsigned short word16;
typedef unsigned int word32;int rijndaelKeySched (word8 k[MAXKC][4], int keyBits,
word8 rk[MAXROUNDS+1][4][4]);
int rijndaelKeyEnctoDec (int keyBits, word8 W[MAXROUNDS+1][4][4]);
int rijndaelEncrypt (word8 a[16], word8 b[16],
word8 rk[MAXROUNDS+1][4][4]);
int rijndaelEncryptRound (word8 a[4][4],
word8 rk[MAXROUNDS+1][4][4], int rounds);
int rijndaelDecrypt (word8 a[16], word8 b[16],
word8 rk[MAXROUNDS+1][4][4]);
int rijndaelDecryptRound (word8 a[4][4],
word8 rk[MAXROUNDS+1][4][4], int rounds);#endif在主程序中，你需要先包含这个头文件，然后就可以调用里面的内容
