Exercises from the Chapter 5 of the programming book

Exercise 1

#include <stdio.h>

int main(void) {

//This is a program to convert Centigrades to Farenheit

float centigrades; //The original temperature

float farenheit; //The conversion

printf("Please insert a temperature, given in centigrades\n");

scanf("%f", &centigrades);

farenheit = (1.8)*centigrades + 32;

printf("The temperature in Farenheit is %f", farenheit);

return 0; }

Exercise 2

#include<stdio.h>

#include<math.h>

int main(void){

//This is a program to calculate the volume of a sphere

float radius;

float pi = 3.14159;

printf("Please insert the radius of the sphere\n");

scanf("%f",&radius);

float volume = ((pi* 4/3)* (pow(radius, 3)));

printf("The volume of the sphere is %f", volume);

return 0;

}

Exercise 3

#include <stdio.h>

int main(void) {

//This is a program to calculate the perimeter of a rectangle

printf("This program is to calculate the perimeter of a rectangle\n");

float height;

float widht;

printf("Please insert height and widht in that order\n");

scanf("%f%f", &height, &widht);

float perimeter = 2*(widht+height);

printf("The perimeter is %f", perimeter);

return 0;

}

Exercise 4

#include <stdio.h>

int main(void) {

float velocity;

printf("This program converts km/h to miles per hour\n");

printf("Please insert a velocity in km/h\n");

scanf("%f",&velocity);

float miles = velocity*0.6213712;

printf("That is equivalent to %f miles per hour\n", miles);

return 0;

}

Exercise 5

#include <stdio.h>

int main(void) {

printf("This is a program where you insert hours and minutes and get the quantity of minutes\n");

float hours;

float minutes;

printf("Please insert quantity of hours\n");

scanf("%f",&hours);

printf("Please insert quantity of minutes\n");

scanf("%f",&minutes);

float total = hours*60 + minutes; //This is the conversion

printf("The total of minutes is %f", total);

return 0;

}

Exercise 6

#include <stdio.h>

#include<math.h>

int main(void) {

printf("This is a program where you insert a quantity in minutes and get the total in hours and minutes\n");

float total;

printf("Please insert quantity in minutes\n");

scanf("%f",&total);

int hours = total/60;

int minutes = total - hours* 60;

printf("The equivalent is %i hours %i minutes", hours, minutes);

return 0;
