Help please! I need my code to use an exception handling method to check if the user entered a correct word.
Here is the logic:
When given two words, the child may claim that transformation of the first word into the second is possible. In this case, the program asks the child to demonstrate the correctness of the answer by typing a sequence of words starting with the first and ending with the second. Such a sequence is an acceptable proof sequence if each word is obtained from its predecessor by swapping a single pair of adjacent letters. For example, the sequence
tops, tosp, tsop, stop, sotp, sopt, spot
proves that the wordtops can be transformed intospot. If the proof sequence is accepted, the child earns a point and play proceeds to the next round with a fresh pair of words.
A proof sequence isrejected if a word cannot be obtained from its predecessor by swapping an adjacent pair of letters, or if the first word in the sequence is not the first word of the pair of words being tested, or if the last word is not the second word in the given pair. When a sequence is rejected, play proceeds to the next round, but the child earns no points.
The child may observe that transformation is not possible. If the child'Â’s answer is correct, he or she receives a point and play proceeds to the next round. If the child'Â’s answer is incorrect and the transformation is indeed possible, the child receives no points. In this case, however, the program displays a correct proof sequence before moving on to the next round of the game.
This is my code at the moment. This is Dev C++
