A composite primary key<span> is a set of several primary </span>keys<span> that, together, uniquely identifies each record.</span>
Primary keys are used as identifiers of composite entities. In this case each primary key combination is allowed only once in the *:* relationship.
Other case where primary keys are used is as identifiers of weak entities, where the weak entity has a strong identifying relationship with the parent entity.
Answer:
c = float(input("Enter the temperature in Celsius: "))
f = c * 1.8 + 32
print("The temperature in Fahrenheit: " + str(f))
k = (f - 32) / 1.8 + 273.15
print("The temperature in Kelvin: " + str(k))
Explanation:
*The code is in Python.
Ask the user to enter the temperature in Celsius
Convert the Celsius to Fahrenheit using the conversion formula and print it
Convert the Fahrenheit to Kelvin using the conversion formula and print it
Answer:
The program to calculate factor can be given as:
Program:
#include <stdio.h> //include header file
int main() //defining main function
{
int a,i; //defining integer variable
printf("Enter any number: "); //print message
scanf("%d",&a); //input value from user end
for(i=1;i<=a;i++) //loop for calculate factor values
{
if(a%i==0) //define condition for factor
{
printf("%d\n",i); //print values
}
}
return 0;
}
Output:
Enter any number: 15
1
3
5
15
Explanation:
In the above C language program the header file is include that provide the use of basic function, in the next line the main method is defined, inside this method two integer variable "a and i" is defined in which variable a is used to take value from user end and variable i is used in loop and conditional statement.
- In the next step, for loop is declare, that start from 1 and end with value of variable a, inside a loop, if block is used that checks (a%i==0), in this if variable i value modeler value equal to 0.
- The loop will use the print function that prints variable "i" element in a new line, which is the factor the values.
It is A outputting (if you want I can show what it says in the dictionary)
