Convert Decimal to Octal



Convert Decimal to Octal

To convert decimal number to octal number in C++ programming, you have to ask to the user to enter the decimal number to convert it into octal number to display the equivalent value in octal format as shown here in the following program.

Following C++ program ask to the user to enter any number in decimal to convert it into octal, then display the result on the screen :
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	long int decnum, rem, quot;
	int i=1, j, octnum[100];
	cout<<"Enter any decimal number : ";
	cin>>decnum;
	quot=decnum;
	while(quot!=0)
	{
		octnum[i++]=quot%8;
		quot=quot/8;
	}
	cout<<"Equivalent octal value of "<<decnum<<" is : \n";
	for(j=i-1; j>0; j--)
	{
		cout<<octnum[j];
	}
	getch();
}

Checking Whether Number is Even or Odd
In this example, if...else statement is used to check whether a number entered by the user is "even or odd". Integers which are perfectly "divisible by 2" are called even numbers. And
