{ if (x > 10) putlong(x / 10);
putchar(x % 10+'0');
}

putlong(a);
return 0;

Answer / cmos

This can be done by recursion.
Since the number of recursive calls is not significant, it does not affect the performance much

printnumber(int i)
{
if(i == 0)
return;
printnumber(i/10);
putchar(’0′ + i%10);
}

which function is used to clear the buffer stream on gcc? for example: I wrote following code on gcc #include<stdio.h> int main(void) { char ch; int a,b; printf("\nenter two numbers:\t"); scanf("%d%d",&a,&b); printf("enter number is %d and %d",a,b); printf("\nentercharacter:\t"); scanf("%c",&ch); printf("enter character is %c",ch); return 0; } in above progarm ch could not be scan. why?plz tell me solution.
