First of all, because you want a string to be insert in txt mean logicaly that
txt should be a pointer (or an array with enough room). And then you use the
built in stream cin, to extract carater from the keyboard, like this.

int main(void)
 char txt[100];        // 100 caracters max can be write (including \r\n and
the null terminated string)

 cout << "Print a string: ";
 cin >> txt;            // whil wait the user to write something until return
as been press

 /* Do something else */

you can even store integer, float, double, ...

int main(void)
 int i;
 float f;
 double d;

 cout << "Write a integer: ";
 cin >> i;

 cout << "Write a float: ";
 cin >> f;

 cout << "Write a double: ";
 cin >> d;

 /* Now you can use  i, f and d as real variable, not string */

double total = i + f + d;
cout << "Total is: " << total;

Thing that can help you!
