Write a Program to convert decimal to OCTAL in C Language
Decimal to octal conversion method:
Step 1: Divide the original decimal number by 8
Step 2: Divide the quotient by 8
Step3: Repeat the step 2 until we get quotient equal to zero.
Result octal number would be remainders of each step in the reverse order.
Decimal to octal conversion with example:
For example we want to convert decimal number 525 in the octal.
Step 1: 525 / 8 Remainder : 5 , Quotient : 65
Step 2: 65 / 8 Remainder : 1 , Quotient : 8
Step 3: 8 / 8 Remainder : 0 , Quotient : 1
Step 4: 1 / 8 Remainder : 1 , Quotient : 0
So equivalent octal number is: 1015
That is (525)10 = (1015)8
#include<stdio.h>
int main(){
long int decimalNumber,remainder,quotient;
int octalNumber[100],i=1,j;
printf(“Enter any decimal number: “);
scanf(“%ld”,&decimalNumber);
quotient = decimalNumber;
while(quotient!=0){
octalNumber[i++]= quotient % 8;
quotient = quotient / 8;
}
printf(“Equivalent octal value of decimal number %d: “,decimalNumber);
for(j = i -1 ;j> 0;j–)
printf(“%d”,octalNumber[j]);
return 0;
}
Sample output:
Enter any decimal number: 50
Equivalent octal value of decimal number 50: 62
- Easy way to convert decimal number to octal number in c
int main(){long int decimalNumber;printf(“Enter any decimal number : “);
scanf(“%d”,&decimalNumber);
printf(“Equivalent octal number is: %o”,decimalNumber);
return 0;
}
Sample output:
Enter any decimal number: 25
Equivalent octal number is: 31
Octal number system: It is base 8 number system which uses the digits from 0 to 7.
Decimal number system:
It is base 10 number system which uses the digits from 0 to 9
