You are required to build a system that can generate a random winning scenario for the T20 cricket world cup. There12 teams which will play knock-out matches in the first round. losing team is out and the winning team moves on. From the twelve teams, six winning teams will play another knock-out match. From these six teams, three winning teams will play against each other on the round robin basis (i.e. team A plays against team B, team B plays against team C, and team C plays against team A). The top two teams from this round will move to the final match. In case all the teams win one match each at this stage, then there will be a toss to move one team to the final while the other two teams will play against each other and the winner moves to the final. The winner of the final match is champion. generate random numbers for matches and toss You are required to use if-else (if-else-if) structure to run the tournament and generate one complete winning scenario randomly.

You are required to build a class to represent the a cup of coffee. Call your class CoffeeCup. A coffee cup will have following characteristics 1. type (sting) // can be mocha, cupaccino, etc 2. temperature (float): represents the measure of temperature in degrees 3. volume (float):// the volume of coffee in the cup in ml liters 4. sugar (int):// no of teaspoons of sugar added to the coffee Provide these methods 1. parameterized constructor CoffeeCup(string t, float temp float vol, int sug) 2. Provide setters for temperature, and sugar and volume. 3. Provide getters of temperature, sugar, volume and type. 4. void heatUp(): //this method represents the process of heating the coffee, the current temperature of coffee goes up by one degree if it is below 100 and stays the same otherwise 5. void cooldown(): the process of cooling down. The temperature goes down by one degree but will not go below 0 6.
