7. Question using macros something like this logic:

int a[10]={60,57,10,5,4,3,2,8,9};

main( )
{
int varx,vary;
for (i=0;i<10;i++)
{
if(varx<a[i])
{
vary=varx;
varx=a[1];
}
else if (vary<a[i])
{ 
varx=vary;
vary=a[i];
}
printf(“%d%d”,varx,vary);
}

8.

print(int (*) ( ));
int a=40;
void main( )
{
print(fn( ));
print(fn( ));
}
print(int (*fn)( ))
{
printf(“%d”,fn( ));
printf(“%d”,fn( ));
}
int fn( )
{
/*static int i=15*/
return (i-=5); 
}
