VC++编码实现的（7，4）海明码，程序运行正确，用VC实验得到在硬软判决下的误码率。再用Matlab讲得到的数据进行绘图。-The realization of (7,4)hamming coding under the VC++.The program runs corectly,resulting the BER under several types.Finally, use the matlab to map with datas.

本代码实现了海明码（1错1修正）式编码，可不定长，输出完成的编码。-This code implements the Hamming code (1 error 1 correction) coding, can be variable length, the output to complete the coding.
