Character Array input on C++

[caffeine43]

How would someone get a character array (ultimately, I want it to be of type String, which I wrote) from user input? I don't think that

char* a;
cin >> a;

works...
Thanks in advance...

This is how I would write it...

main()
{
    char aChar[80];

    cout << "Enter your string";
 
    cin >> aChar;
    cout <<  aChar;

    return 0;
}

You would need to include your iostream.h file too.

caffeine43,

Keep posting you questions here; however, I want to offer you another useful link.

Also, "C++, The Complete Reference, Second Edition," by Herbert Schildt, is an excellent book for answering those programming questions.

Is there a way to do that without using an array of a specific size?

 

[Bowser]

You need to allocate space for your array. If the string size is unknow, you would then try dynamic allocation (new & delete), which requires an algorithm that checks the size of the string each time a user inputs a character. The algorithm would then allocate the neccessary space in memory for storing the larger string.

Your looking at some pointer manipulation and possibly a specialized function or enhanced class. There might be something in the C++ I/O that will perform this task for you, but I don't know if there is.

The easiest way to do this is



#include <iostream>
using namespace std;

int main(){
char* string;
cin >> (string = new char);
cout << string;
system("pause");
}

This makes an array of char variables.
The string variable points to the first char in the array
