DES加密的MFC实现,主要包括两部分组成，有字符串加密和文件加密两种模式，实现了3DES功能，让加密更安全(including string and files by DES)

说明：  SIFT特征匹配算法的PPT，很适用,是学习SIFT的好资料.(SIFT feature matching algorithm of the PPT, it is applicable, is a good learning SIFT information.)

说明：  msp430单片机的电压表程序。用430的ad转换在用数码管显示电压值(msp430 microcontroller voltmeter program. The ad with the 430 conversion voltage value with a digital LED display)

（1） 分析QPSK调制、解调原理，并画出其系统框图； （2） 产生等概率且相互独立的二进制序列，作为待传输的信号，并画出其波形； （3） 进行8PSK调制，分别画出I、Q两支路信号经过乘法器后的波形以及8PSK调制波形； （4） 产生均值为0，方差为1的加性高斯随机噪声，画出其时域波形及频谱； （5） 将加性高斯随机噪声作为传输信道的干扰，画出接收端信号的时域图； （6） 进行8PSK解调，输出解码序列，画出解调后信号波形； （7） 计算系统信噪比、传输误码率。((1) analysis of QPSK modulation, demodulation, and draw the system block diagram (2) have equal probability and independent binary sequence as a signal to be transmitted, and draw the waveform and (3) 8PSK modulation, Draw the I, Q two way signal multiplier waveform and 8PSK modulation waveform (4) to produce zero mean and variance of an additive Gaussian random noise, to draw the time-domain waveform and spectrum ( 5) the additive Gaussian random noise interference as a transmission channel, to draw the time-domain diagram of the receiver signal (6) 8PSK demodulator output decoding sequence, draw the demodulation of the signal waveform computing system (7) signal-to-noise ratio, the transmission bit error rate.)

60-按键从右至左输入(60- button from right to left input)

交通信号灯控制，可以调红绿黄灯时间，有紧急模式和夜间模式( Traffic lights control, you can adjust the red and yellow light time, emergency mode and night mode)

说明：  c语言用来进行数值计算的相关程序和论文，非常棒棒棒(C language for numerical calculation of the relevant procedures and papers, very good)

在桌面上显示TXT文件内容，实现信息发送功能

it is my first project last year about menu..system i save it in txt file. but it is as runable or executable program in turbo C++ 3.0. JUST open it in note pad then ("save as") removale.cpp.
