**NOTE: The following code for “Converting Decimal To Binary Using C language” has been written and performed on Ubuntu OS, To run the following code in Windows on Turbo C, You need to add #include<conio.h> as one of the header files and getch() at the end of the code before main() closing brace “}”.

#include<stdio.h>
void main(){
int b,n,m[50],count=0,i=0,k;
printf("Enter a Number: ");
scanf("%d",&b);
while(b!=0){
n=b%2;
b/=2;
m[i]=n;
count+=1;
i++;
}
for(k=count-1;k>=0;k--){
printf("%d",m[k]);
}
}

Explanation for the Above Program:

• Input a number from the user ------> b
• Run the while loop with the condition b is  not equal to Zero -----------> b!=0
• Divide the input variable by 2 to get the remainder and store it in another variable---------> n = b % 2
• Divide the input value again to get the quotient and store it in the input variable itself -------> b/=2
• Store the Remainder in an array variable and increment the index i by 1---------->m[i]=n
• "count" variable above keep tracks of the number of times the loop runs.---------->count+=1
• Print the array values using for loop with "k" as a looping variable which runs from backwards "count" to 0. ------------>for(k=count;k>=0;k--)
• Print the array index values.

Output:
