    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.

How many times will its boolean expression (i = 0) && (n > = 0)) is satisfied. Express both sets of answers using powers of 2. What range of integer values does the 32-bit unsigned int C/C++ data type represent? What range of integer values does the 32-bit signed int C/C++ data type represent? Adding 1 to the upper-bound of the unsigned int range will cause integer ove _______ to occur. T or F? Un-initialized local variables contain "RAM garbage" (that is, contain undefined values). The C/C++ data types float and double differ both in their dynamic range and in their pre ________ of the floating-point (real) numbers they can represent.

    12. (Continuing 10) What is the arity of the restricted operator? ? Hint Recall, the arity of an operator is the reckon of operands the operator requires. Ce specimen, 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. Transcribe a separate nested if/else-statement (1) to show the string exact Zero and regular y to3 when the integer x is resembling to 0; (2) to show Negative and regular y to 2 when x is short than 0; and (3) and to show Positive and regular y to 1 when x is superior than 0.

    ANSWERS-

    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 want to verification junction 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 attempt is terminated.

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

    Generalization
    Count(loop condtion)=1+ Count(Loop attempt)

    17-18.
    int sum=0;
    while(n>=0 && x>=0)
    {
    sum+=n;
    if(sum>x)
    break;

    n=n-1;
