In this tutorial, i am going to show you how to convert binary number to Octal number in c program with the help of for loop, while loop and function.
All C Programs to Convert Binary to Octal
- C Program to Convert Binary to Octal using While Loop
- C Program to Convert Binary to Octal using For Loop
- C Program to Convert Binary to Octal using Function
C Program to Convert Binary to Octal using While Loop
#include <stdio.h> #include<math.h> int main() { int i, octal = 0, decimal = 0; long binary; printf("Enter the Binary Number = "); scanf("%ld", &binary); i = 0; while(binary != 0) { decimal = decimal + (binary % 10) * pow(2, i); i++; binary = binary/10; } i = 1; while(decimal != 0) { octal = octal + (decimal % 8) * i; decimal = decimal / 8; i = i * 10; } printf("The octal Value = %d\n", octal); }
The result of the above c program; as follows:
Enter the Binary Number = 121010 The octal Value = 112
C Program to Convert Binary to Octal using For Loop
#include <stdio.h> #include<math.h> int main() { int i, remainder, octal = 0, decimal = 0; long binary; printf("Enter the Binary Number = "); scanf("%ld", &binary); for(i = 1; binary != 0; i = i * 2, binary = binary / 10) { remainder = binary % 10; decimal = decimal + remainder * i; } for(i = 1; decimal != 0; i = i * 10) { octal = octal + (decimal % 8) * i; decimal = decimal / 8; } printf("\nThe octal Value = %d\n", octal); }
The result of the above c program; as follows:
Enter the Binary Number = 1101410 The octal Value = 172
C Program to Convert Binary to Octal using Function
#include <stdio.h> #include <math.h> int binaryTooctal(long binary) { int octal = 0, i, decimal = 0; for(i = 0; binary != 0; i++) { decimal = decimal + (binary % 10) * pow(2, i); binary = binary/10; } for(i = 1; decimal != 0; i = i * 10) { octal = octal + (decimal % 8) * i; decimal = decimal / 8; } return octal; } int main() { long binary; printf("Enter the Binary Number = "); scanf("%ld", &binary); printf("The octal Value = %d\n", binaryTooctal(binary)); return 0; }
The result of the above c program; as follows:
Enter the Binary Number = 11011011 The octal Value = 333
