Programs for practice
In the program below, we've asked user to enter any number in decimal to convert it into octal, in C++
Source Code: Decimal to Octal Conversion
/* C++ Program - Decimal to Octal Conversion */
#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();
}
Output
Enter any decimal number :50
Equivalent octal value of 50 is :
62
