C program to convert binary to Octal; Through this tutorial, we will learn how to convert binary number to Octal number in c program using for loop, while loop and function.
Programs to Convert Binary to Octal in C
Let’s use the following programs to convert binary to octal using while loop, for loop and function in c:
- 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 output 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 output 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 output of the above c program; as follows:
Enter the Binary Number = 11011011 The octal Value = 333
