Convert Decimal to Binary



Convert Decimal to Binary

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

Following C++ program ask to the user to enter any number in decimal format to convert it into binary, then display the result on the screen :
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	long int decnum, rem, quot;
	int binnum[100], i=1, j;
	cout<<"Enter any decimal number : ";
	cin>>decnum;
	quot=decnum;
	while(quot!=0)
	{
		binnum[i++]=quot%2;
		quot=quot/2;
	}
	cout<<"Equivalent binary value of "<<decnum<<" :\n";
	for(j=i-1; j>0; j--)
	{
		cout<<binnum[j];
	}
	getch();
}

Code Print the Words Ending with Letter S

C Example Code Nested Printf Statements
C Program code to demonstrate nested printf statements. String will be first printed while executing inner printf. Length of the string "abcdefghijklmnopqrstuvwxyz". So printf will

Binary Counting Method Generate Subset
Algorithm takes the input of "n" data element and 'prints all possible combination'. Function to 'Print array element' according to the code in the 'Argument List'. For that, it generates n

C++ Codes Heap's Algorithm Permutation
The time complexity of this algorithm: 'O(n!)'. This algorithm 'takes the input' of "N" distinct numbers. It fixes an element at the end of the array and permutes the "remaining numbers"

C++ Programming Bubble Sort Algorithm
The Bubble Sort is a simple sorting algorithm that 'repeatedly' steps through the List to be sorted, compares each pair of adjacent items and swaps them if they're in the wrong order.
