#include<stdio.h>
#include<conio.h>

#define Greatest(X,Y) X>Y?X:Y

int main()
{
int x,y;
scanf("%d %d",&x,&y);
printf("%d",Greatest(x,y));
getch();
}

Answer / senthil

#define Greatest(a,b) (a>b)?a:b

Answer / subbu

While defining macro's for each parameter enclosing brackets
is preferred. For finding out greatest of two numbers better
way writing macro is as below.

#define Greatest(a,b) ((a)>(b))?(a):(b)


If this method not followed, the in the following example
results will be wrong.


#define Product(a,b) (a*b) /* Wrong method */

Bcz if call is done as below

Product(2+3, 4+5) then result will come as (2+3*4+5) = 19
instead of 45.

#include<stdio.h>
#include<conio.h>
#define big(a,b) (a>b)?a:b
void main()
{int x,y;
clrscr();
printf("enter the valus of x and y:\n");
scanf("%d%d",&x,&y);
printf("the biggest value is",big(x,y)");
getch();
}

Given a number N, product(N) is the product of the digits of N. We can then form a sequence N, product(N), product(product(N))… For example, using 99, we get the sequence 99, 99 = 81, 81 = 8. Input Format: A single integer N Output Format: A single integer which is the number of steps after which a single digit number occurs in the sequence. Sample Test Cases: Input #00: 99 Output #00: 2 Explanation: Step - 1 : 9 * 9 = 81 Step - 2 : 8 * 1 = 8 There are 2 steps to get to this single digit number. Input #01: 1137638147
