我已經寫了代碼爲十進制數轉換到不給所需的輸出二進制數

Question

//program to give binary equivalent of a decimal number without using recurssion 
#include<stdio.h> 
#include<math.h> 
int main(void) 
{ 
    int i=0,num,bin=0; 
    printf("enter number : "); 
    scanf("%d",&num); 
    while(num>0) 
    { 
     bin+=((float)(num%2))*pow(10.0,(float)i++); 
     num/=2; 
    } 
    printf("Binary equivalent is : %d",bin); 
    getchar(); 
    return 0; 
} 

此代碼這麼想的提供像7輸入所需的輸出，但是對於一些numbers.Can請您協助提供所需的輸出我出去找錯誤。

 #include<stdio.h> 
    void main() 
     { 
     int a; 
     scanf("%d",&a); 
     while(a>0) 
     { 
     printf("%d",a%2); 
     a=a/2; 
     } 
     }
