Femur and Humerus problems

#1  Modify the program so that it converts the output values from inches to feet. The input would still be entered in inches. Use a single value for the output, such as 6.5 feet.

#include <stdio.h>
#include <math.h>
int main(void)
{
/* Declare variables. */
double femur, femur_ht_f, femur_ht_m, humerus, humerus_ht_f,
humerus_ht_m;
/* Get user input from the keyboard. */
printf("Enter Values in Inches. \n");
printf("Enter femur length: \n");
scanf("%lf",&femur);
printf("Enter humerus length: \n");
scanf("%lf",&humerus);
/* Compute height estimates. */
femur_ht_f = (femur*1.94 + 28.7)/12;
femur_ht_m = (femur*1.88 + 32)/12;
humerus_ht_f = (humerus*2.8 + 28.2)/12;
humerus_ht_m = (humerus*2.9 + 27.9)/12;
/* Print height estimates. */
printf("\nHeight Estimates in Feet \n");
printf("Femur Female Estimate: %5.2f \n",femur_ht_f);
printf("Femur Male Estimate: %5.2f \n",femur_ht_m);
printf("Humerus Female Estimate: %5.2f \n",humerus_ht_f);
printf("Humerus Male Estimate: %5.2f \n",humerus_ht_m);
/* Exit program. */
return 0;
}

#2 Modify the program so that it asks the user to enter the values in feet. The program would then need to convert the values in feet to inches before doing the computations. The output would also print the output heights in feet, as in 6.5 feet.

#include <stdio.h>
#include <math.h>
int main(void)
{
/* Declare variables. */
double femur, femur_ht_f, femur_ht_m, humerus, humerus_ht_f,
humerus_ht_m;
/* Get user input from the keyboard. */
printf("Enter Values in feet. \n");
printf("Enter femur length: \n");
scanf("%lf",&femur);
printf("Enter humerus length: \n");
scanf("%lf",&humerus);
/* Compute height estimates. */
femur=femur*12;
humerus=humerus*12;
femur_ht_f = (femur*1.94 + 28.7)/12;
femur_ht_m = (femur*1.88 + 32)/12;
humerus_ht_f = (humerus*2.8 + 28.2)/12;
humerus_ht_m = (humerus*2.9 + 27.9)/12;
/* Print height estimates. */
printf("\nHeight Estimates in Feet \n");
printf("Femur Female Estimate: %5.2f \n",femur_ht_f);
printf("Femur Male Estimate: %5.2f \n",femur_ht_m);
printf("Humerus Female Estimate: %5.2f \n",humerus_ht_f);
printf("Humerus Male Estimate: %5.2f \n",humerus_ht_m);
/* Exit program. */
return 0;
}

#3 Modify the program so that it reads the input values in inches and then estimates the output heights using feet and inches. (Note that you are printing two output values for each height estimate.)

 #include <stdio.h>
#include <math.h>
int main(void)

humerus_ht_m_i = (humerus*2.9 + 27.9);
/* Print height estimates. */
printf("\nHeight Estimates in Feet \n");

printf("Humerus Male Estimate: %5.2f \n",humerus_ht_m_i);
/* Exit program. */
return 0;
}

#4 Modify the program so that it reads the input values in feet and inches, and then estimates the output heights using feet and inches. (Note that you are reading two input values for each bone and you are printing two output values for each height estimate.)

#5 Modify the program so that it reads the bone values in centimeters and outputs the height estimates in centimeters. (Recall that 1 in = 2.54 cm.)

#include <stdio.h>
#include <math.h>
int main(void)
{
/* Declare variables. */
double femur, femur_ht_f, femur_ht_m, humerus, humerus_ht_f,
humerus_ht_m;
/* Get user input from the keyboard. */

Arduino Blink Light (in class)

const kled=2; void setup() { pinMode(2, OUTPUT); } void loop() { digitalWrite(kled, HIGH); delay(1000); digitalWrite(kled, LOW); delay(1000); }

Arduino chasing LED
I set up a few different ideas of how this could work.
#1 most basic back and forth

const int kLed = 2;

const int kLed2 = 3;

const int kLed3 = 4;
const int kLed4 = 5;

void setup()
{
    pinMode(kLed, OUTPUT);
    pinMode(kLed2, OUTPUT);
    pinMode(kLed3, OUTPUT);
    pinMode(kLed4, OUTPUT);
}

void loop()
{
    digitalWrite(kLed, HIGH);
    delay(50);
    digitalWrite(kLed, LOW);
    delay(50);
    digitalWrite(kLed2, HIGH);
    delay(50);
    digitalWrite(kLed2, LOW);
    delay(50);
    digitalWrite(kLed3, HIGH);
    delay(50);
    digitalWrite(kLed3, LOW);
    delay(50);
    digitalWrite(kLed4, HIGH);
    delay(50);
    digitalWrite(kLed4, LOW);
    delay(50);
    digitalWrite(kLed3, HIGH);
    delay(50);
    digitalWrite(kLed3, LOW);
    delay(50);
    digitalWrite(kLed2, HIGH);
    delay(50);
    digitalWrite(kLed2, LOW);
    delay(50);
}
#2 little more complex first light stays on and creates chain reaction

 const int k_numLEDs = 4; const int kPinLeds[k_numLEDs] = {2,3,4,5}; void setup() { for(int i = 0; i < k_numLEDs; i++){ pinMode(kPinLeds[i], OUTPUT); } } void loop() { for(int i = 0; i < k_numLEDs; i++){ digitalWrite(kPinLeds[i], HIGH); delay(100); } for(int i = k_numLEDs - 1; i >= 0; i--){ digitalWrite(kPinLeds[i], LOW); delay(100); } }

#3 code that makes the first example speed up and slow down

 const int kLed = 2; const int kLed2 = 3; const int kLed3 = 4; const int kLed4 = 5; void setup() { pinMode(kLed, OUTPUT); pinMode(kLed2, OUTPUT); pinMode(kLed3, OUTPUT); pinMode(kLed4, OUTPUT); } void loop() { digitalWrite(kLed, HIGH); delay(150); digitalWrite(kLed, LOW); delay(175); digitalWrite(kLed2, HIGH); delay(200); digitalWrite(kLed2, LOW); delay(175); digitalWrite(kLed3, HIGH); delay(150); digitalWrite(kLed3, LOW); delay(125); digitalWrite(kLed4, HIGH); delay(100); digitalWrite(kLed4, LOW); delay(75); digitalWrite(kLed3, HIGH); delay(50); digitalWrite(kLed3, LOW); delay(25); digitalWrite(kLed2, HIGH); delay(50); digitalWrite(kLed2, LOW); delay(75); digitalWrite(kLed, HIGH); delay(100); digitalWrite(kLed, LOW); delay(125); digitalWrite(kLed2, HIGH); delay(150); digitalWrite(kLed2, LOW); delay(175); digitalWrite(kLed3, HIGH); delay(200); digitalWrite(kLed3, LOW); delay(175); digitalWrite(kLed4, HIGH); delay(150); digitalWrite(kLed4, LOW); delay(125); digitalWrite(kLed3, HIGH); delay(150); digitalWrite(kLed3, LOW); delay(100); digitalWrite(kLed2, HIGH); delay(50); digitalWrite(kLed2, LOW); delay(50); digitalWrite(kLed, HIGH); delay(100); digitalWrite(kLed, LOW); delay(125); digitalWrite(kLed2, HIGH); delay(150); digitalWrite(kLed2, LOW); delay(175); digitalWrite(kLed3, HIGH); delay(200); digitalWrite(kLed3, LOW); delay(175); digitalWrite(kLed4, HIGH); delay(150); digitalWrite(kLed4, LOW); delay(75); digitalWrite(kLed3, HIGH); delay(50); digitalWrite(kLed3, LOW); delay(25); digitalWrite(kLed2, HIGH); delay(50); digitalWrite(kLed2, LOW); delay(75); }

/*print*/
printf("The molecular weight of the entered values is %4.1f ",weight);

(NOTE: Tried to make it so it would also compute which amino acid it was but couldnt figure it out.)
