Solution 1

You asked the same question here (not same, but very similar):

input data into 2d char array[^]

Since you are using C++, the proper way to do this is using std::string. There's rarely a good reason to use char* based strings in C++ code.

Quick example:

C++

std::string str[100];
for (int i=0; i<100; i++)
{
        cin >> str[i];
}

Not fair. :)

I had to get up from my char (yuk yuk) to talk to the boss. When I started my answer, there were no other answers posted.

Sorry :-)

BTW you have stayed away from C++ too long. The code snippet you gave him will crash on the first iteration since the char*s have not been allocated! *grin*

Good! My work here is done. :)

Solution 2

I think you want this instead (I may be wrong, my C++ foo has long gone unused):

C#

char* str[100];
for (int i = 0; i < 100; i++)
{
    cin >> str[i];
}
