Answer 1

i)

#include<iostream>
using namespace std;

int main()
{
    int i,j;
    //loop to print first 4 lines
    for(i=0;i<4;i++)
    {
        //for every line it prints the '*' (2*i)+1 times
        for(j = 1;j <= (2*i)+1;j++)
        cout << "*";
       
        cout <<"\n";
    }
    //loop to print last 3 lines
    for(i=2;i>=0;i--)
    {
        //for every line it prints the '*' (2*i)+1 times
        for(j = 1;j <= (2*i)+1;j++)
        cout << "*";
       
        cout <<"\n";
    }
    return 0;
}

ii)

#include<iostream>
using namespace std;
int main()
{
    double shares = 750,price = 35.00,total,stock_alone,commission;
    //calculates the total amount paid for stock
    stock_alone = shares * price;
   
    //calculates the commission for of 2 percent
    commission = (stock_alone * 2)/100;
    //calculates the amount paid
    total = stock_alone + commission;
    //displays the amount paid for stock alone
    cout << "The amount paid for stock alone: $"<<stock_alone;
    //displays the amount for commission
    cout << "\nThe amount of commission: $"<<commission;
    //displays the total amount paid
    cout <<"\nThe total amount paid: $"<<total;
    return 0;
}

III)

#include<iostream>
using namespace std;
int main()
{
    char name[5] = "Ram",address[20] = "Gandhi nagar";
    char city[20] = "Hyderabad",state[20]= "Telangana";
    int zip = 501001;
    char major[10] = "Major";
   
   
    cout << "Name: "<<name<<"\nAddress: "<<address<<",City: "<<city<<",State: "<<state<<",Zip code: "<<zip<<"\nMajor:"<<major;
