Question

C++

Hey, I really need help with this lab. I don't understand the function part at all. It'll be great way for me to understand. Than you

Functions and loops: Write a program that will ask the user which type of triangle they would like to draw on the characters. The choices are screen with left-top-big left-bottom-big right-top-big right-bottom-big Get the user's choice, ask how big it should be, and then draw the shape. After each successful drawing, ask the user if they would like to draw another one. Continue until they choose not to draw any more. All of the major tasks should be done in tunctions (7 in total The main program should only have a loop, a decision structure based on the menu choice and function calls. The following functions will be required (names can vary): menu0-ask the user for a number between 1 and 4 and read in their response. If their answer is anything outside the desired range, write out an error message and repeat the input. Return the legal integer menu choice. getsize0 ask the user for the maximum number of characters in the shape. The response must be an integer that is in the range of 1-10. If any input is outside this range, write an error message and have the user repeat the input untilavalid input is received. Return the legal integer size value. getRepeatChoice0 ask the user if they would like to draw another shape. Read their response into a char variable. their response is anything other than "Y" or 'N' (upper or lower case) write outan emor and read in a new response until or N is found. Return the char response. leftTopBig0 receives the maximum size as a parameter and draws the specified shape. Returns nothing. leftBotBig0 receives the maximum size as a parameter and draws the specified shape. Returns nothing. rightTopBig0-receives the maximum size as a parameter and draws the specified Returns nothing. rightBotBig0 receives the maximum size as a parameter and draws the specified Returns nothing. Each function must be written with aprototype before the main program and a definition after the main program. name block comment before each function definition stating what it does. The following is a complete example of a sample run including error detection Which triangle do you want to draw? Left-Top-B Left Bottom-Big Big 4 Right-Bottom-Big

Answer 1

Here is the code for you:

#include <iostream>
using namespace std;
int menu()
{
cout<<"Which triangle do you want to draw?"<<endl;
cout<<"1 - Left-Top-Big"<<endl;
cout<<"2 - Left-Bottom-Big"<<endl;
cout<<"3 - Right-Top-Big"<<endl;
cout<<"4 - Right-Bottom-Big"<<endl<<endl;
int choice;
cin>>choice;
while(choice < 1 || choice > 4)
{
cout<<"Illegal choice, try again: ";
cin>>choice;
}
return choice;
}
int getSize()
{
cout<<"Please enter the maximum size (1-10): ";
int size;
cin>>size;
while(size < 1 || size > 10)
{
cout<<"size must be in range of 1 - 10, try again: ";
cin>>size;
}
return size;
}
char getRepeatChoice()
{
cout<<"Draw another? (Y/N) ";
char another;
cin>>another;
while(another != 'y' && another != 'Y' && another != 'n' && another != 'N')
{
cout<<"Please enter Y for yes or N for no: ";
cin>>another;
}
return another;
}
void leftTopBig(int max)
{
for(int i = 0; i < max; i++)
{
for(int j = 0; j < max-i; j++)
cout<<"*";
cout<<endl;
}
cout<<endl;
}
void leftBotBig(int max)
{
for(int i = 0; i < max; i++)
{
for(int j = 0; j <= i; j++)
cout<<"*";
cout<<endl;
}
cout<<endl;
}
void rightTopBig(int max)
{
for(int i = 0; i < max; i++)
{
for(int j = 0; j < i; j++)
cout<<" ";
for(int j = 0; j < max-i; j++)
cout<<"*";
cout<<endl;
}
cout<<endl;
}
void rightBotBig(int max)
{
for(int i = 0; i < max; i++)
{
for(int j = 0; j < max-i-1; j++)
cout<<" ";
for(int j = 0; j <= i; j++)
cout<<"*";
cout<<endl;
}
cout<<endl;
}
int main()
{
while(true)
{
int choice = menu();
int size = getSize();
switch(choice)
{
case 1:   leftTopBig(size); break;
case 2:   leftBotBig(size); break;
case 3:   rightTopBig(size); break;
case 4:   rightBotBig(size); break;
}
char again = getRepeatChoice();
if(again == 'n' || again == 'N')
return 0;
}
}

And the output screenshot is:
