need this in c++

10. Cycle 1. A data structure has to be accepted by a laboratory instructor before implementation. 2. The source code has to be split into header (,h) and source (,cpp) files. 3. All functions have to be commented in the dorygen style. 4. Any permutation of command line switches has to be handled. 5. The program executed without parameters prints a short user's manual. 6. The program has to accept slightly imperfect input data. Write a program for searching cycles in a directed graph. Input file holds edges of a graph in the following format: (startnode)(endnode) The edges are separated with commas, eg: 23,13,33,33 The output file keeps the found cycles (each cycle in its own line) or a message that there are no cycles in the graph. The program is run in command line with switches: -g input file with graph description - output file with cycles Running the program with no parameters prints a short help how to use the program
