Question

Write a recursive function takes a word string as input argument and reverse the word. Print out the results of recursive calls. Also write a main program accepts input from the user and then call the recursive function.

Example:
Enter a word: hello
h
eh
leh
lleh
olleh

Answer 1

IN C++ language

Answer 2

void reverse(int,string)
{
string str;
int len = strlen(str);
char c;
for(i=1;i<len:i++)
{
for(j=1;j<i;j++)
{
c=getchar(str,len-j);
printf("%c",c);
}
}
}

it may require som modificatons but the logic will be the same as i havnt used c for long time.

That's in C, and it's also not recursive :(

try one of these, recursive but I suck at C++ (it also does it a little differently from your example): http://ideone.com/cnH7r

Using the C++ library function, best way to do it, but I doubt it's recursive http://ideone.com/ewIsg#li_ewIsg
