Describe and algorithm for converting a string to a floating-point value. Data from a console is initially read in from a string and must be converted to a floating-point format. Be sure to consider scientific notation as well. A string value of -705.7481 x 10^20for example needs to be parsed in some way to interpret it as an a floating point value .

A related (but easier problem) is parsing an integer from a string, and you might want to start there (in c++ this is called atoi ).
