please key in any 5 digits number : 56789

and the ouput is
5678 9
567 89
56 789
5 6789
how to write those program......
my idea is like this...
#include <stdio.h>
void main()
{
int num;
float num1,num2,num3,num4;
float r1,r2,r3,r4;
printf("please key in any 5 digit number:");
scanf("%d",&num);
num1=num/10;
num2=num/100;
num3=num/1000;
num4=num/10000 ;
r1=num%10;
r2=num%100 ;
r3=num%1000 ;
r4=num%10000 ;
printf("\n %.0f %.0f",num1,r1);
printf(" \n %.0f %.0f",num2,r2);
printf(" \n %.0f %.0f",num3,r3);
printf(" \n %.0f %.0f",num4,r4);
}

the problem occur when i entered nnumber 56789.It output become
rubbish..
but if i key in 12345 the program excute nicely.....
anyone can tell what wrong with my coding...

Change 'float' to 'int' and the formats to %i.

Could it be that your 'int' has only 16 bits? Then the largest number
it is going to handle is 32767.

but if i key in 12345 the program excute nicely.....

Efficient? Your code is efficient enough. It's not generic enough,
so it can't do the same output for any number (two-digit to fifty-digit
ones, for example), but that's not the goal, right?
