#print
Write a program
pair(a,b)
which accepts as arguments two pointers to integers
and swaps the integers if necessary so that the
first argument points to the larger one; that is
int x,y;
x = 9;
y = 15;
pair( &x, &y);
results in x being 15 and y 9. Leave the program
on file "pair.c"; compile, test it, and type "ready".
#once #create tzaqc.c
main()
{
int x,y;
y=200;
x = 0;
pair(&y, &x);
if (x != 0 || y != 200)
return(1);
pair(&x,&y);
if (x != 200 || y != 0)
return(1);
x = 30;
y = 23097;
pair(&x,&y);
if (x != 23097 || y != 30)
return(1);
return(0);
}
