The following program implements all features of Data Structures STACK, QUEUE and LIST using generic functions (templates in C++). User have choice for selection the data type float,integer or character to use the data structures. Also there is a game which takes 3 positive integers as input a,b and c. a represent the number of digits, b represent the maximum sum of digits and c represent the maximum total sum of all the numbers formed during the game. The score of the game is the highest number formed. The user after inputting the parameters will sequentially enter the digits, and the game will automatically stops when the sum of the numbers formed exceeds c. For example is user enter 3,13,200 as parameters and the digits entered sequentially is 1,1,9,5,9,6,5,4, 8,9.... the numbers that will be stored in the stack will be 119,5,9,11,12,9.... using the restrictions. The stack is then sorted using another stack and the top element is your score. The Game is generalized for decimal numbers also i.e., input can be 1,1,.,9,5,.9,...... so on.
Here is an sample output:
