a. To identify and correct the error in the given codes.

Explanation of Solution

The error is in the first line of the code. The “if” statement shouldn’t end with a semicolon.

The correction involves the removal of the statement terminator (;) at the end of the first line of code because if there will be semicolon the puts statements won’t get executed.

The correct code will be −

if(age>=65)
puts("Age is greater than or equal to 65\n");
else
puts("Age is less than 65\n");

b. To identify and correct the error in the given codes.

Explanation of Solution

There is as such no error with the syntax or logical of the given code segment.However, it is always recommended to initialize the variables with some initial values in order to avoid problem of garbage value. Therefore, the variable “total” should be initialized with 0.

The correct code

int x=1, total =0;
while(x<=10)
{
    total+=x;
++x;
}

c. To identify and correct the error in the given codes.

Explanation of Solution

There are two errors in the given code.

The first correction involves the correction of name of the keyword while from “While” to “while”.

The second correction involves the enclosing the second and third statement withincurly braces.

So, the correct code will be as follows-

while(x<=100)
{
    total+=x;
++x;
}

d. To identify and correct the error in the given codes.

Explanation of Solution

The given code has the error in the while statement. The given statement is an infinite loop because y will keep on increasing (provided base value of y is positive) and will always be greater than 0.

The above problem can be solved by decrementing the y-value instead of incrementing.

The correct code will be as follows-

while(y>0)
{
printf("%d\n",y);
--y;
}

I would like to get help to resolve the following case
Last Chance Securities The IT director opened the department staff meeting today by saying, "I've got some good news and some bad news. The good news is that management approved the payroll system project this morning. The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid possible fines and penalties for noncompliance. The bad news is that the system must be installed by January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in advance, the system should have a modular design if possible, and the vice president of finance would like to announce the new system in a year-end report if it is ready by mid-December." Tasks 1. Why is it important to define the project scope? How would you define the scope of the payroll project in this case? 2. Review each constraint and identify its characteristics: present versus future, internal versus exter- nal, and mandatory versus desirable. 3. What…
2. Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.
