Question

Implement the following logic in C++, Use appropriate data types. Data types are represented as either numeric (num) or string.

start
string name
string address
num item //use int
num quantity
num price //use double as data type
num SIZE = 6
num VALID_ITEM [SIZE] = 106, 108, 307, 405, 457, 688 //use int as data type
num VALID_ITEM_PRICE [SIZE] = 0.59, 0.99, 4.50, 15.99, 17.50, 39.00 //use double as data type
num i
bool foundIt = false
string MSG_YES = "Item available"
string MSG_NO = "Item not found" get name, address, item, quantity
i = 0
while i < SIZE
if item == VALID_ITEM [i] then
foundIt = true
price = VALID_ITEM_PRICE [i]
endif
i = i + 1
endwhile
if foundIt == true then
print MSG_YES
print quantity, " at " , price, " each"
print "Total ", quantity * price
else
print MSG_NO
endif
stop

Follows are the modified code in c++ language:

#include<iostream>//header file

#include<string>//header file

using namespace std;

int main()//main method

{

string name,address, MSG_YES, MSG_NO;//defining string variable

int item,quantity,size=6, i=0;//defining integer variable

double price;//defining double variable

int VALID_ITEM[]={106,108,307,405,457,688};//defining integer array and assign value

double VALID_ITEM_PRICE[]={0.59,0.99,4.50,15.99,17.50,39.00};//defining double array and assign value

bool foundIt=false;//defining bool variable

MSG_YES="Item available";//use string variable to assign value

MSG_NO = "Item not found"; //use string variable to assign value

cout<<"Input name: ";//print message

cin>>name;//input value in string variable

cout<<"Input Address: ";//print message

cin>>address;//input value in string variable

cout<<"Input Item: "<<endl;//print message

cin>>item;//input value in string variable

cout<<"Input Quantity: "<<endl;//print message

cin>>quantity;//input value in string variable

while(i <size)//defining while that checks i less then size

{

if (item ==VALID_ITEM[i]) //use if block to match item in double array

{

foundIt = true;//change bool variable value

price = VALID_ITEM_PRICE[i];//hold item price value in price variable

}

i++;//increment the value of i

}

if (foundIt == true)//use if to check bool variable value equal to true

{

cout<<MSG_YES<<endl;//print value

cout<<"Quantity "<<quantity<<" at "<<"Price "<<price<<"each"<<endl;//print value

cout<<"Total"<<quantity*price;//calculate the total value

}

else//else block

cout<<MSG_NO;//print message

}

Step-by-step explanation:

In the above given C++ language modified code, four-string variable " name, address, MSG_YES, and MSG_NO", four integer variable "item, quantity, size, and i", and "integer and double" array is defined, that holds values.

In the string and integer variable "name, address, and item, quantity", we input value from the user-end and use the while loop, which uses the if block to check the "item and quantity" value from the user end and print its respective value.
