1)Ans:
its simple find the string length say K
now run a a loop from 0 to K/2 incrementing by 1 every time
and swap the elements as
for(i=0;i<K/2;i++)
{
temp=a[i];
a[i]=a[K-(i+1)]
a[K-(i+1)]=temp;
}/*this is to reverse the string*/
2)Ans:
for(i=0;i<K;i++)
{
printf("%c",a[i]);
if((i+1)%2==0)
printf(" ");
}/*this is for printing in groups*/
