Coding Practice

Write the function printCakeInfo, which prints the cake’s information in the format “This is a color, diameter inch diameter cake with/without icing.” If name does not have the value “n/a”, printCakeInfo prints out “Happy birthday name! Your cake is color, has a diameter inch diameter, and comes with/without icing.” Select the Parsonsprob tab for hints for the construction of the code.

#include <iostream> using namespace std; struct Cake { string name; string color; double diameter; bool has_icing; }; // Write your code for the printCakeInfo function here. int main() { Cake c1 = { "n/a", "red", 12.5, true }; printCakeInfo (c1); Cake c2 = { "Tom", "white", 10, false }; printCakeInfo (c2); }

Write the function printCakeInfo, which prints the cake’s information in the format “This is a color, diameter inch diameter cake with/without icing.” If name does not have the value “n/a”, printCakeInfo prints out “Happy birthday name! Your cake is color, has a diameter inch diameter, and comes with/without icing.” Use the lines to construct the code, then go back to complete the Activecode tab.

        void printCakeInfo (Cake c) {
---
string printCakeInfo (Cake c) { #paired

    if (c.name == "n/a") {

        if (c.has_icing) {

Write the function changeCakeDiameter, which takes a Cake and a double as a parameter. changeCakeDiameter then multiplies the original diameter by the double and modifies the cake to have this new diameter. Select the Parsonsprob tab for hints for the construction of the code.

#include <iostream> using namespace std; struct Cake { string name; string color; double diameter; bool has_icing; }; void printCakeInfo (Cake c); Cake makeCake (); // Write your code for the changeCakeDiameter function here. int main() { Cake original = { "John", "green", 8.5, true }; changeCakeDiameter (original, 2); printCakeInfo (original); } ==== void printCakeInfo (Cake c) { if (c.name == "n/a") { if (c.has_icing) { cout << "This is a " << c.color << "," << c.diameter << " inch diameter cake with icing." << endl; } else { cout << "This is a " << c.color << "," << c.diameter << " inch diameter cake without icing." << endl; } } else { if (c.has_icing) { cout << "Happy birthday " << c.name << "! Your cake is " << c.color << ", has a " << c.diameter << " inch diameter, and comes with icing." << endl; } else { cout << "Happy birthday " << c.name << "! Your cake is " << c.color << ", has a " << c.diameter << " inch diameter, and comes without icing." << endl; } } } Cake makeCake () { Cake input; string name, color; double diameter; char icing; cout << "Name: "; cin >> name; input.name = name; cout << "Color: "; cin >> color; input.color = color; cout << "Diameter: "; cin >> diameter; input.diameter = diameter; cout << "Icing? (y/n) "; cin >> icing; if (icing == 'y') { input.has_icing = true; } else { input.has_icing = false; } return input; }

Write the function changeCakeDiameter, which takes a Cake and a double as a parameter. changeCakeDiameter then multiplies the original diameter by the double and modifies the cake to have this new diameter. Use the lines to construct the code, then go back to complete the Activecode tab.

        void changeCakeDiameter (Cake &c, double scale) {
---
void changeCakeDiameter (Cake c, double scale) { #paired
---
string changeCakeDiameter (Cake c, double scale) { #paired
---
    c.diameter *= scale;
---
    c.diameter; #distractor
---
    c.diameter = c.diameter * 2; #distractor
---
}
        

Write the struct Shirt, which has the instance variables color and size. Select the Parsonsprob tab for hints for the construction of the code.

#include <iostream> using namespace std; // Write your code for the struct Shirt here. int main () { Shirt t = { "blue", 'L' }; }

Write the struct Shirt, which has the instance variables color and size. Use the lines to construct the code, then go back to complete the Activecode tab.

        struct Shirt {

Write the struct Outfit, which is a nested structure that has a Shirt, Pants, and has_hat. Select the Parsonsprob tab for hints for the construction of the code.

#include <iostream> using namespace std; struct Pants { char size; string material; }; struct Shirt { string color; char size; }; // Write your code for the struct Outfit here. int main () { Shirt t = { "blue", 'L' }; Pants p = { 'S', "denim" }; Outfit o = { t, p, true }; }

        struct Outfit {

    Pants p;
---
    bool has_hat;
---
    int has_hat; #distractor
---
};
        

Write the changeShirts and changePants functions, which both take an Outfit as a parameter. changeShirts also takes a Shirt as a parameter and changePants also takes a Pants as a parameter. Each function modifies the Outfit and changes the shirt or pants to the new input. Select the Parsonsprob tab for hints for the construction of the code.

#include <iostream> using namespace std; void printOutfit(Outfit o); struct Shirt { string color; char size; }; struct Pants { char size; string material; }; struct Outfit { Shirt s; Pants p; bool has_hat; }; // Write your code for the changeShirts function here. // Write your code for the changePants function here. int main() { Shirt t = { "blue", 'L' }; Pants p = { 'S', "denim" }; Outfit o = { t, p, true }; printOutfit (o); Shirt newShirt = { "red", 'M' }; Pants newPants = { 'M', "khakis" }; changeShirts (o, newShirt); changePants (o, newPants); printOutfit (o); } ==== void printOutfit (Outfit o) { cout << "Shirt: " << o.s.color << " and " << o.s.size << "; Pants: " << o.p.size << " and " << o.p.material << "; "; if (o.has_hat) { cout << "has hat" << endl; } else { cout << "does not have hat" << endl; } }
