Answer:
a) SQL Query:
SELECT population
FROM bsg_planets
WHERE name='Caprica';
b) SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE lname!='Adama';
c) SQL Query:
SELECT name, population
FROM bsg_planets
WHERE population > 2600000000
d) SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE age IS NULL;
Explanation:
a) Write a SQL query to find the population of the planet named 'Caprica'
Syntax:
SELECT Column
FROM TableName
WHERE Condition;
For the given case,
Column = population
TableName = bsg_planets
Condition = name='Caprica'
SQL Query:
SELECT population
FROM bsg_planets
WHERE name='Caprica';
Therefore, the above SQL query finds the population of the planet named 'Caprica' from the table bsg_planets.
b) Find the first name, last name, and age of people from bsg_people whose last name is not 'Adama'
Syntax:
SELECT Column1, Column2, Column3
FROM TableName
WHERE Condition;
For the given case,
Column1 = fname
Column2 = lname
Column3 = age
TableName = bsg_people
Condition = lname!='Adama'
SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE lname!='Adama';
Therefore, the above SQL query finds the first name, last name and age of people whose last name is not 'Adama' from the table bsg_people.
c) Find the name and population of the planets with a population larger than 2,600,000,000
Syntax:
SELECT Column1, Column2
FROM TableName
WHERE Condition;
For the given case,
Column1 = name
Column2 = population
TableName = bsg_planets
Condition = population > 2600000000
SQL Query:
SELECT name, population
FROM bsg_planets
WHERE population > 2600000000
Therefore, the above SQL query finds the name and population of the planets with a population larger than 2,600,000,000 from the table bsg_planets.
d) Find the first name, last name, and age of people from bsg_people whose age is NULL
Syntax:
SELECT Column1, Column2, Column3
FROM TableName
WHERE Condition;
For the given case,
Column1 = fname
Column2 = lname
Column3 = age
TableName = bsg_people
Condition = age IS NULL
SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE age IS NULL;
Therefore, the above SQL query finds the first name, last name and age of people whose age is NULL from the table bsg_people.
Answer:
- #include <stdio.h>
- int main()
- {
- const double piVal = 3.14159;
- double sphereVolume = 0.0;
- double sphereRadius = 0.0;
- sphereRadius = 1.0;
- sphereVolume = 4.0/ 3.0 * piVal * sphereRadius * sphereRadius * sphereRadius;
- printf("Sphere volume: %lf\n", sphereVolume);
- return 0;
- }
Explanation:
Firstly we can identify the formula to calculate volume of sphere which is
Volume = 4/3
With this formula in mind, we can apply this formula to calculate the volume of sphere in Line 10. This is important to perform floating-point division 4.0/3.0 to ensure the resulting value is a floating value as well. Since we have been given piVal and sphereRadius, we can just multiply the result of floating-point division with piVal and sphereRadius and get the sphereVolume value.
At last, display the sphere volume using printf method (Line 13).
