    Very simple for someone who knows C++. Please answer all of them 12. (Continuing 10) What is the arity of the conditional operator? ? Hint Recall, the arity of an operator is the number of operands the operator requires. For example, the + operator requires 1 operand (a unary operator) and the % operator requires 2 operands (a binary operator). A: 0 B: 1 C: 2 D: 3 E: 4 13-14. Write a single nested if/else-statement (1) to display the string literal Zero and set y to3 when the integer x is equal to 0; (2) to display Negative and set y to 2 when x is less than 0; and (3) and to display Positive and set y to 1 when x is greater than 0. Hint Will you need to use blocks (compound statements)? 15-16. How many times will the body of the while-statement shown below execute? How many times will its boolean expression ( i <- 11) be evaluated? generalization about the relationship of these 2 counts which holds for all while-statements. times times.

    What is the arity of the conditional operator? ? Hint Recall, the arity of an operator is the number of operands the operator requires. For example, the + operator requires 1 operand (a unary operator) and the % operator requires 2 operands (a binary operator). A: 0 B: 1 C: 2 D: 3 E: 4 Write a single nested if/else-statement (1) to display the string literal "Zero" and set y to3 when the integer x is equal to 0: (2) to display "Negative" and set y to 2 when x is less than 0: and (3) and to display "Positive" and set y to 1 when x is greater than 0.

    12. D=3 , ternary takes three operands.
    13-14.
    if(x==0)
    {
    cout<< “zero”;
    y=3;
    }
    else if(x<0)
    {
    cout<<“Negative”;
    y=2;
    }
    else
    {
    cout<<“Positive”;
    y=1;
    }
    There is a insufficiency to correction combination statements.

    15-16.

    1.i=1, loop exexutes
    2.i=3, loop enacts
    3.i=5, loop enacts
    4.i=7, loop enacts
    5.i=9, loop enacts
    6.i=11, loop enacts
    7.i=13, loop effort is terminated.

    The loop enacts 6 times and the loop situation is checked 7 times.

    Count(loop condtion)=1+ Count(Loop effort)
