实验名称：关于数组下标越界的异常操作。 实验要求：自定义String类，当数组下标越界调用异常处理。 初步认识：通过C++的异常处理建立在三个关键字try 、catch和throw实现。(Laboratory name: about array subscript bounds of abnormal operation. Experimental requirements: custom String class, when the array subscript transitions exception handling. Preliminary understanding: by c++ exception handling is based on three key words the try and catch and throw.)

STEGNOGRAPHYIn digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it.
