write a full c++ programto find the smallest value amongst the following numbers {10,98,87,16,88,46,100} and display the results in terms of positive /index of smallest value and the smallest values itself { hint use arrays}

1. Write a program using Function Concept to Calculate Perimeter of Circle, Square, Triangle and Rectangle.

i. Function calPerimeterCircle that do not accept arguments and do not return value.

ii. Function calPerimeterSquare that do not accept arguments and return value.

iii. Function calPerimeterTriangle that accept arguments and do not return value.

iv. Function calPerimeterRectangle that accept arguments and return value

2. Please refer the following formula as guidance :

a. Perimeter of Circle = 2 π r : r = radius , use π= 22/7

b. Perimeter of Square = 4a : a = side

c. Perimeter of Triangle = a+b+c : a=side1, b=side2 and c= side3

d. Perimeter of Rectangle = 2 +(l+w) : l=length, w= width 

Write a program that determines the frequency of each char in an input le. Your program

should

• read in an unknown number of chars from an input le named input.txt,

• using a function written by you, determine the frequency of occurrence of each char in

the list

• write each char followed by the frequency to the output le output.txt.

• The chars should appear in the output le in the same order as they rst appeared in

the input le.

First draw a 

ow chart and then attempt the code.

Example 1

Example input and output les can be seen in Listings 9 and 10.

In traditional way, there are three classes: TRUCK (number, name , NoOfWheel, Price, Capacity, 

EnginePower, TypeOfConsump), BUS (number, name , NoOfWheel, Price, NoOfSeat, 

EnginePower, TypeOfConsump, Color, Speed), CAR (number, name , NoOfWheel, Price, 

NoOfSeat, EnginePower, TypeOfConsump, Color, Speed).

Divide the above three classes into two base classes and three derived classes. Each class will 

contain two member functions, getdata() to get that class data from user and putdata() to display that 

class data on the screen. How the above member data of three classes will be distributed into five 

classes as shown in the following diagram.

Write the Boolean expression (in Sum of Products form) for the logic circuit that will have a 1 output when A = 0, B = 0, C = 1 and A = 1, B= 1, C= 0, and a zero (0) output for all other input states. Draw the logic diagram for this circuit. 

You need to take a matrix of any size, doubles all the elements that are positive and add 10 to all

the elements that are zero or negative. Then you need to add all the elements of the array and

display the results as follows, with the total value displayed to 3 decimal places:

The sum of the matrix elements is 75.322

i. Write a function called matrixfx

Use the input matrix xin[n,m] sent by the script,

 Initialise your out variable xout [n,m]

 to perform the above calculations on the positive and negative numbers, depending on

the values of each element of the matrix – Tip use one logical array mask to build the

matrix xout [n,m]. No loops!

ii. Write a script called matrixAdd

 Use the function matrixfx to manipulate the test data as indicated above (y).

 Initialise the necessary variables to use nested loops to add up the elements of the matrix

y.

 Your display should be formatted to display the final total as indicated above.

Use the aggregation (composition)

concept to define and implement the

class line(pl.x, pl.y, p2.x, p2.y) by using

two points variables P 1, and P2 of type

point2D class defined in QI. Beside the

two points Pl and P2, the line class has

the following functions: print(),

MoveRel(Dx,Dy) (use the point2D's

MoveRel(Dx,Dy) function of the two

points to achieve that), line(),

Use the point2D class as base class

to derive a new class called

Point3D(x,y,z). In addition to the

derived variables and functions

(methods) the new class has the

variable z with the functions setZ(z1),

getZ(), MoveRel(Dx,Dy,Dz), print(), and

the constructers point3D(),

point3D(x1,y1,z1,pColor), the destructor

-point3D(). Determine which function

is an override function and which one

is an overloaded function of the base

class.

Define the class point2D(x,y) for

the x, y coordinates. The class has x, y

and color as member variables and as

member function has setXY(x1,y1),

setColor(pColor), MoveRel(Dx,Dy),

getX(), getY(), getColor(pColor), Print(),

the constructers point2D(),

point2D(x1,y1,pColor), the destructor

-point2D(). The MoveRel(Dx, Dy)

function changed the x, y coordinates

by the amount of Dx, and Dy,

respectively (ex: x=x+Dx, y=Y+Dy).

Determine which function is accessor

and which one is mutator.
