Convert Octal number to Decimal number



Convert Octal number to Decimal number

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

Following C++ program ask to the user to enter any octal number to convert it into decimal, then display the result on the screen :
		
#include<iostream.h>
#include<conio.h>
#include<math.h>
void main()
{
	clrscr();
	long int octnum, decnum=0;
	int i=0;
	cout<<"Enter any Octal Number : ";
	cin>>octnum;
	while(octnum!=0)
	{
		decnum = decnum + (octnum%10) * pow(8, i);
		i++;
		octnum=octnum/10;
	}
	cout<<"Equivalent Decimal Value = "<<decnum;
	getch();
}

C Codes Calculates Prints the Value of nPr
In the following c program we are calculating the value of nPr based on the given values of n and r. nPr can also be represented as P(n,r). The formula of P(n, r) is: n! / (n - r)!. P(5, 2)=5!

Calculates Sum of Odd and Even Numbers
C program code find the sum of odd and even numbers from 1 to N. Take Number N upto which we have to find the sum as input. Using for loop take the elements one by one from 1

Arithmetic, Assignment, Logical, Bitwise
Arithmetic operators: +, -, *, /, %, addition, subtraction, multiplication, division, modulo. Assignments operators in C++ are: =, +=, -=, *=, /=, %=. Auto increment and decrement

Find the Odd Element given an Array with
Will hold XOR of two odd occurring elements. Xor will basically be xor of two odd occurring elements. Get one set rightmost bit in the xor2. Now divide elements in two sets. XOR

Convert Uppercase Character to lowercase
To convert "from uppercase to Lowercase" in 'C++', enter character in uppercase to convert it into 'Lowercase' and display the equivalent character in lowercase. To change uppercase

C coding to Accessing 2-D Array Elements
Program code to access every 2-D Array we requires 2 subscript variables. y - Refers the Row number. x - Refers Column number. a[1][0] refers element belonging to first row

C Program Flip all Bits of a Binary Number
Flipping a bit means toggling or inverting the current bit status. If the current bit is set i.e. 1 than invert it to 0 and vice versa. Flip all bits of a binary number you can run loop from 0...

Trim Leading & Trailing white spaces from
I already explained how to remove leading as well as trailing white space characters from a given string. In this program we will Combine the logic of both in a single program. Logic to
