Convert Binary to Octal

Convert Binary to Octal

To convert binary to octal in C++ Programming, you have to ask to the user to enter any number in binary to convert it into octal to display the equivalent value in octal on the screen as shown in the following program.

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

C++ Checks the Alphabets is Vowel or Not - To check whether the input alphabet is vowel or not a vowel in C++, Enter a Character, then check the character for Vowel. The character is vowel, only if it's equal to a, A, e, E, i, I, o, O

Code find power of number using for loop - C program to find power of a number using for loop. Input base and exponents from user. Store it in two variables say base and expo. Declare & initialize another variable to store

Nested Namespace in C++ Programming - In C++ programming, you can create nested 'namespaces'. One namespace can be a part of another namespace. Simply we can create namespace X, which will contain namespace

C Program Copy Strings without by strcpy - You can use the 'strcpy()' function to copy the content of "one String to another" but, this C Program 'copies the Content' of one string to another manually without "strcpy()" function.

C Insert an Element in a Specified Position - C Program inserts an element in a specified position in a given array. C Programming language code takes a user input and inserts the desired element in the specified position.

The C++ Booth's Multiplication Algorithm - "Multiply two Signed numbers" using Booth's algorithm. Booth's multiplication algorithm is a multiplication algorithm that multiplies two signed 'binary numbers' in two's complement

Relational Operators in C++ programming - In C++, This category of the operators is used to compare different values. The result of the operation is a Boolean value. The "Relational" operators are used in the form Operand1 and

C Program Printing Upside Down Triangle - Upside down triangle. A triangle with all sides equal is called "Equilateral Triangle". We shall now see how to print stars char, in equilateral triangle shape, but 'upside-down'. Equilateral
