Float separation

On local content: write and run C programs
Machine on purpose: to master a simple C program editing, compiling, running and general process connection

My program:

#include<stdio.h>
int main()
{
    float a;
    scanf("%f",&a);
    printf("%d %d",a*1000/1000,(a-a*1000/1000)*1000);
    return 0;
}
