Conversion: Decimal to Binary

#include <stdio.h>

int main(void){
    int decimal;
    int binary;
    int greater_power;

//  decimal = 24;
    greater_power = 1;

    scanf("%d",&decimal);

    //Caluclate the greatest power of 2.
    while (greater_power < decimal){

        greater_power *= 2; // It will keep doubling until it will be greater or equal than the decimal.

//      printf("%d\n", greater_power); // To test how the loop code works :>
    }


    //Example:Great Power = 16|Decimal = 24
    while (greater_power > 0){  //Loops until Greater Power reach 0.

        binary *= 10; //Shift bits to left. IF TRUE: adds 1 |IF FALSE: still multiplied, but 1 will not be added (0).

        if (greater_power <= decimal){ // IF TRUE: 16 <= 24.

            binary += 1; //The Binary 0, will be added by 1. Binary = binary + 1.

            decimal -= greater_power; //Decimal (24) - Greater Power (16) = Decimal will become (8).

        } //Repeat process until Decimal is 0 or = Great Power.

        greater_power /= 2; // IF FALSE: Great Power divided by 2. Until Great Power is <=.
