When I was a reptile, I always used a very simple and rude method to analyze the page and find the law directly. Later on the internet saw the gumbo, tried a bit, found that really good, so recommend to everyone.The following transfers are from:

In writing a C + + program, there is always the case of finding a small string from a string, for in C we often use either strstr () or STRCHR (). For C + + strings, we tend to use find ().C + +: #inlcude C: #include Find (): finds a specified

In C + +, the system has overloaded the left-shift operator ">", respectively, to make it available for input and output, but the input-output processing object can only be a data type built into the system. System overloading these two operators
