Can anyone help with these coding questions
4. Nested Logic Use program TicketPrice for exercises 6-7. // Program TicketPrice prints the price for a ticket to // the Wonderland park based on an age input from the keyboard #include <iostream> using namespace std; int main () int age; cout <« "Welcome to Wonderland Park! Please enter your age:" <« endl; cin >> age; if ( age <= 3 ) cout << "Children under 3 can enjoy free admission. <« endl; /* TO BE FILLED IN FOR EXERCISE 6 */ else cout << "Your ticket price is $50. " « endl; return 0; Exercise 6. Add two else-if statements so that children 4 to 12 years old (including 4 and 12) only need to pay $20 for ticket and senior citizens 65 or above only need to pay $30 for ticket. Run your program using the following values as input: 2, 4, 12, 37, 65, 71. Show the statements you added and the results for the input values in the report. Note: Remove any redundant condition in the logical expressions you wrote for this exercise, otherwise you may only earn partial credit even if the results are correct. Exercise 7. Replace the following statement in Exercise 6 cout << "Your ticket price is $50. " << endl; with compound statements to check if the guest is eligible for other discounts. Display the following message: Are you a student or veteran? Please enter Y for Yes and N for No. If the answer is "Y", then display the following message: You may be eligible for discounted price. Please show your ID to our staf. Otherwise (the answer is “N"), display the original message of price $50. Show your compound statements and the results of a few testing cases.

Expert Solution
Exercise-6

We just have to add some of the else if statements so that there are more conditions for other age groups-

if(age<=3)

cout<<"children under 3 can enjoy free tickets. "<<endl;

else if(age>=4 && age<=12){

cout<<"your ticket price is $20. "<<endl;

else if(age>=65)

cout<<"your ticket price is $30. "<<endl;

else{

cout<<"your ticket price is $50. "<<endl;

Program-

#include <iostream>

using namespace std;

int main()
{
    int age;
    
    cout << "welcome to wonderLand park! Please enter your age:"<<endl;
    
    cin >> age;
    if(age<=3){

cout << "children under 3 can enjoy free tickets."<<endl;}

else if(age>=4  && age<=12){

cout << "your ticket price is $20."<<endl;}

else if(age>=65){

cout << "your ticket price is $30."<<endl;}

else{

cout << "your ticket price is $50."<<endl;}

    return 0;
}
