Programming exercise for newbies

Here's a small coding exercise for programming newbies. I asked this question in an interview to a computer science graduate and she could not solve it. It was surprizing. The computer science, IT engineers should start thinking on their own - mugging up the stuff from book doesn't help.

So here's a simple programming challenge [for newbies]:-

Write a program that accepts a new text strings, one on each line, but prints a line number before it accepts the input. The lines are then printed out, with each word individually reversed.

That is, the output should look like -

1: Hello, this is The Big K
2: This is line number 2
3: ___

*******************************
1: K giB ehT siht ,olloeH

etc.

I hope you got the problem. Use any damn computer programming language of your choice. The only bet is - you crack this question on your own. The purpose is to make you think, not to test your Google search skills.

All the best.

uh.. say what? 😛

It'll be interesting to code this in a language you are not familiar with 😀

I do not know any computer language as I am in 1st year but still, i will try using HTML code and JavaScript.

<html>
<body>
<script language="JavaScript">
a=parse(prompt("text here"));
document.write(+a);
document.write(+"1: Hello, this is The Big K");
document.write(+"2: This is line number 2");
document.write(+"3: ___");
</script>
</body>
</html>

I guess it is correct.

Wow! I never expected such a simple solution! 😁

I guess another simple solution would be to use "printf" or "cout" keywords to generate the output. Right?

This work's is this what you wanted?
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
int main()
{
char inp[255];
int i = 0;
vector<string> inpTxt;
string str;
cout << "Input lines to stop input 'end'" << endl;
while(strcmp(inp,"end"))
{
cout << ++i << ":" ;
cin.getline(inp, 255);
str.assign(inp);
reverse(str.begin(), str.end());
inpTxt.push_back(str);
}
cout << endl << "Reversed Output" << endl;
for(vector<string>::iterator it = inpTxt.begin(); it!= inpTxt.end(); it++)
cout << (*it).c_str() << endl;
}

==== TEST RUN =====
Input lines to stop input 'end'
1:who is this
2:i am not going to see google
3:i remember few things
4:bye
5:end
Reversed Output

Please read the question again. I've provided sample input/output. That should be enough to give you a hint.
