C Program for Base Conversion from Decimal to Binary

The decimal (base ten) numeral system has ten possible values (0,1,2,3,4,5,6,7,8, or 9) for each place-value. In contrast, the binary (base two) numeral system has two possible values, often represented as 0 or 1, for each place-value

the base of each individual number may be specified by writing it as a subscript of the number. For example, the decimal number 156 may be written as 156₁₀ and read as “one hundred fifty-six, base ten”. The binary conversion of 156 is 10011100 may be specified as “base two” by writing it as 10011100₂.

Code:

//C Program to Convert Decimal to Binary

#include<stdio.h>

#include<conio.h>

void main()

{

int n,i=0,b[100],j;

clrscr();

printf(“Enter decimal number: “);

scanf(“%d”,&n);

while (n>0)

{

b[i]=n%2;

n=n/2;

i++;

}

printf(“Binary is: “);

j=i-1;

for (i=j;j>=0;j–)

{

printf(“%d”, b[j]);

}

getch();

}
