Algorithm, C and C++ Programs to find Closure From Functional Dependencies

In this post we will see how to find closure of an attribute or a set of attributes. Before learning how to get closure, we should first know what is a closure. Closure of a given set C is the set of attributes that are functionally determined by the set C under the set of functional dependencies F. There can be closure for any set. Every attribute in the set whose closure is to be found out, will be a member of its closure set C⁺ also. Consider an example:

Conditional Operator in C and C++

Conditional Operator is an operator which is substitutive for if-else statements. It is a ternary operator (operator which operates on 3 operands). It is often called ?: operator. The operands are expression1, expression2 and expression3. The syntax is as follows:

expression1 ? expression2 : expression3

The expression expression1  will be evaluated always. Execution of expression2 and expression3 depends on the outcome of expression1. expression1 is checked whether true or not. It is considered like a boolean variable. The outcome of an expression is true if it has a non zero value. If its value is zero, the outcome of expression is false. If the expression1 is true, then expression2 is evaluated. If the expression1 is false, then expression3 is evaluated. Consider the following example:

How to Hard Reset Nokia E63

C and C++ Program to Check Whether a Given Number is Even or Odd

C and C++ programs to check whether a given number is Odd or even

C Program

#include<stdio.h>
void main()
{
int n;
printf("Enter an integer\n");
scanf("%d",&n);
if ( n%2 == 0 )
printf("Even");
else
printf("Odd");
}

C++ Program

#include<iostream.h>
void main()
{
int n;
cout<<"Enter an integer\n";
cin>>n;
if ( n%2 == 0 )
cout<<"\nEven";
else
cout <<"\nOdd";
}

C Program to Sort a Matrix Column wise using Pointers

This is a c program to sort a mxn matrix column wise in ascending order using pointers. To sort column wise in descending order, just replace the '>' symbol in the comparing line of code into '<'. That part of the code is marked with a comment 'comparison'.

#include<stdio.h>

main()

{

int a[7][7],i,j,k,m,n,temp;

//reading
printf("enter number of rows of matrix\n");
scanf("%i",&m);
printf("enter number of columns of matrix\n");
scanf("%i",&n);
printf("enter the elements\n");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
scanf("%d",&a[i][j]);
}
//displaying
printf("the matrix you entered:\n");
for(i=0;i<m;i++)
{
printf("\n");
for(j=0;j<n;j++)
{
printf("%4d",*(*(a+i)+j));
}
}
