in c++ with result please

Summary analyze a set of DNA strands for validity, CG percentage, and overall stability Write a complete C++ program to analyze a set of DNA strands input from the keyboard. For each strand, output the strand followed by validity, CG percentage, and overall stability For example, given this input sequence CCGA ACTGATGC ACTGATTX TTCAA Your program should output the following ccca: valid, cc-75, highly stable ACTGATGC: valid, CG-50%, stable ACTGATXc: invalid TTCAA: valid, co-20*, unstable In terms of overall stability, if the CG percentage is 75 or greater, than the DNA strand is considered 'highly stable' If the CG percentage is e 75 but 50 or greater, it's considered "stable Less than 50 but 25 or greater is considered 'less stable': And a CG percentage
