A)
Relational Operators:
Relational operators are used to compare numeric and character values using the following operators:
- Greater than (>)
- Less than (<)
- Greater than or equal to (>=)
- Less than or equal to (<=)
- Equal to (==)
- Not equal to (!=)
These operators will determine whether specific relationship exists between two values of same type.
Relational Expression:
Relational operators are “binary”, so it needs two operands for comparison. Consider the following expression using the less-than operator:
A < B
- The above expression is called a “relational expression”. It is used to find whether “A” is less than “B”.
- Relational expression is also referred as “Boolean expression”, because the resultant value of all relational expression is either “True” or “False”. But the states of Boolean values are stored as 0 and 1.
- Hence, if the resultant value of relational expression is 0, then the expression is “False”. If the resultant value of relational expression is 1, then the expression is “True”.
Evaluating the given relational expression is “true” or “false”:
The below expressions are evaluated using the values that are given:
x=5;
y=6;
z=8;

Procedure specification: • Prototype: int max3(int a, int b, int c). - Parameter(s): a, b, c = Z. - Return value: the largest number among a, b and c. • e.g, max3(10, 20, 30) = 30, max3(1, 1, 1) = 1, max2(10, -20, -30) = 10 Main procedure specification: • • • Read three integers, a, b and c, using input macro. Call max3 procedure to find the largest. Display the result returned from your procedure using output macro.arrow_forwardBackground: Game Rules The rules to the (dice) game of Pig: You will need 2 dice. To Play: a. The players each take turns rolling two die. b. A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c. During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d. The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns.
