Those questions are for you to work out, so that you will learn from the experience. It is OK to ask for hints, but not for entire solutions.

The third task claims that the input is one integer, but the expected output comes from some indexed set. Where did that set came from?

plz tell me how i can write the condition of smallest number in while loop

[awais rana]

plz plz plz tell the solution of 3rd programm.........only one program plx plx plz....i have already waste the 3 hours at this problem

Post your "3 wasted hours" code ;)

[awais rana]

#include <iostream>

using namespace std;

int main ()
{
int n=1,smallest=0;

while ( n>0 )
{
cout<<"Enter a number"<<endl;
cin>> n;
}

smallest=n;

for (int i = n; i > 0 ; i++)
{
if(n>smallest)
smallest=n;
}

cout<< "smallest non-negative number is :" << smallest << endl;

return 0;
}

what is problem in this code??????????

[Daleth]

Two major issues are immediate:
1) Your for loop will run forever for any positive n. Did you mean to decrement instead? you could do either for(int i(n); i > 0; --i) or for(int i(1); i < n+1; ++i).
2) Your if condition in the for loop is backwards. If n is smaller (not larger) than the current smallest number, then you assign n to smallest.

Edit:
But the whole code will eventually always say 1 is the answer (if n is any positive number).

I understand that you want it, but it is your responsibility to do your own homework. This would be cheating. We are not allowed to do your homework for you. But, if you have any questions about it, we can help you with that.

We are not going to give you the code for the entire program. But, you can ask questions about each problem.

[awais rana]

#include <iostream>

using namespace std;

int main ()
{
int n=1,smallest=0;

while ( n>0 )
{
cout<<"Enter a number"<<endl;
cin>> n;
}

smallest=n;

for (int i = n; i > 0 ; i++)
{
if(n>smallest)
smallest=n;
}

cout<< "smallest non-negative number is :" << smallest << endl;

return 0;
}
