#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();
}

What is the output from this program? #include <stdio.h> void do_something(int *thisp, int that) { int the_other; the_other = 5; that = 2 + the_other; *thisp = the_other * that; } int main(void) { int first, second; first = 1; second = 2; do_something(&second, first); printf("%4d%4d\n", first, second); return 0; }
