Ive printed 3 smiley faces so far. How can I use arrays to print out 50 smiley faces to screen with the use of for loops? Here is where im at.

 

void setup ()
{
  size(500,500);
  smooth();
}

void draw()
{
  background(200);
  smileyface(100,250); //giving three smiley faces their coordinates
  smileyface(225,250);
  smileyface(350,250);
}

void smileyface(int x, int y)
{
  pushMatrix();
  translate(x,y);
  //stroke(0);
  //strokeWeight(70);
  ellipse(0,-35,120,-120); //the body
  ellipse(-19.5,-65,30,30); //left eye
  ellipse(19.5,-65,30,30); //right eye
  arc(0,-30,40,40,0,HALF_PI); // smile
  popMatrix();
}
 

 

 

I have an exam tomorrow and im clueless. I cant even get print out 5 random numbers between 1-10 onto the screen. Please help. This is what I have so far.

 

float[] x= new float[5];

void setup()
{
  size(200, 200);
  smooth();
  for (int i=0; i<x.length;i++)
  {
   // x[5]= random(256);
    text(x[i], 20, 10+i*20);
  }

//  x[i]= random(200);
}
//void draw()

How do we make our cirlces look 3d like this?

I tried making 3d spheres but all i have is this:

  //for( int i=120; i<=520; i+=100)
  //{
   // line(140, i, 600, i);
    //line(i, 100, i, 560);
  //}
  //for( int i=220; i<560; i+=100)
  //{
  //  line(i, 60, i, 620);
  //}
}

void draw()
{
  background(0, 0, 255);

Im having trouble printing out things to the console. my code is supposed to average out a students 2 test average and print it out to the console. I cant seem to find out what i did wrong. Please help. Thanks. Below is my code. 

 

void setup()
{
 new student("ben", 75, 60, 5);
 
}

 

 

void printStudent(student name)
{
  println("Name:" +name.getName());
  println("Exam 1 Grade:" + name.getExam1());
  println("Exam 2 Grade:" + name.getExam2());
  println("Bonus:" + name.getBonus());
  println("GPA:" + name.calcGPA());
}

 

 

class student
{
  String name;
  float e1, e2;
  int bonus;

  student(String n, float ex1, float ex2, int b)
  {
    name=n;
    e1=ex1;
    e2=ex2;
    bonus=b;
  }
  float calcGPA()
  {
    float gpa= (e1+e2+bonus)/2;
    return gpa;
  }

  float getExam1()
  {
    return e1;
  }
  float getExam2()
  {
    return e2;
  }
  float getBonus()
  {
    return bonus;
  }
  String getName()
  {
    return name;
  }
  void setExam1(float e)
  {
    e1=e;
  }
  void setExam2(float e)
  {
    e2=e;
  }
  void setBonus(int b)
  {
    bonus=b;
  }
}

 

When I pressed the required key, the color changes but when I let go, the color go back to black. How do we get the color to stay? Heres my code.

 

void setup()
{
  size(400,400);
}
void draw()
{
  for(int x=40;x<200;x+=20)
  {
    //for(int j=40;j<200;j+=20)
    {
    //ellipse(x,j,5,5);
    line(x,250,150,10);
    line(x*2,250,150,10);
    //strokeWeight(2);
    line(40,250,40,400);
    line(360,250,360,400);
   
    }
    if(keyPressed)
    {
      if(key=='r')
     {
       rect(40,250,320,160);
       triangle(150,10,140,40,160,22);
       fill(255,0,0);
     }
     if(key=='b')
     {
       rect(40,250,320,160);
       triangle(150,10,140,40,160,22);
       fill(0,0,255);
     }
     if(key=='g')
     {
       rect(40,250,320,160);
       triangle(150,10,140,40,160,22);
       fill(0,255,0);
     }
    }

Write a program that multiplies three numbers together and prints the results to the screen. Do this for 5 sets of numbers. Use a function that returns the product of the three numbers to do this.

You may have lines like this in your code:

GIve me an example please so I can understand better. I missed class due to a snow day.

My assignment is to write 10 numbers in a row in active mode. Is there a way to use new float to get random numbers to show up on the screen? Heres my code.

 

 

//Declaring, assigning, and creating array
float[] x= new float[10];
void setup()
{
  size(400,400);

}
void draw()
{
   //Using a for loop to intialize array
  for(int i=0; i<10; i++)
  {
    text(x[i],10,10+i*20);
   // x[i]= random(200);
  }

Is there a way to use for loops to make an array of number appear on the screen. Hard to explain but ill show you the code. How can I use for loops so I wouldnt have to use the text function 10 times?

 

int[] x= {5,88,76,54,63,89,15,66,84,155};
 
void setup()
{
  size(200,200);
  //for(int i=20; i<100; i+=20)
  {
    text(x[0],10,10);
    text(x[1],10,30);
    text(x[2],10,50);
    text(x[3],10,70);
    text(x[4],10,90);
    text(x[5],10,110);
    text(x[6],10,130);
    text(x[7],10,150);
    text(x[8],10,170);
    text(x[9],10,190);
  }
}
