C++ Programming Code Examples C++ > Conversions Code Examples 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(); }
