Question

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: valid,CG-758,highly CCGA: ACTGATGC: ACTGATXC invalid TTCAA: stable valid, CG-50%, stable valid, CG-208,unstable n 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 75 but 50 or greater, it's considered "stable. Less than 50 but 25 or greater is considered "less stable". And a CG percentage> DNA; 11 read first DNA strand: while (DNA !.. "#") // if not end of input marker #, process input :
