promp the number of character for the user in a string

[kevinros]

Write your question here.

 #include<iostream>
#include<string>
using namespace std;

int count(string);

int main()
{
string str;
 int num;

cout << "Number of characters: ";
cin >> num;

if (num > 1){
cout << "Enter text: " ;
getline(cin,str);
cout << "Text: " << str.size(num);}
else 
	cout << "Allocation failure!";


return 0;
}

the Out put expected is

number of characters: 13
enter tex: nospaceshere!
text: nospaceshere!




other test

number of character :-10
allocation failure!
I was trying to resolve this activity with differents methods but I feel that I 'm so closing.
thank you.

What exactly are you trying to do on line 18?

Note that str.size() will return the size of the entered string.

Ok,I could change something from this code....but the thing that I can't do is to limit the string inputted by the user.
for example :
We are allocating space for a 2 character string but the user
is giving us more. We need to stop at two characters

> Number of characters: 2
> Enter Text: Hi Bob!
> Text: Hi Bob!\n
expected:HI
I could run this code using this but,I can limit the string,
thank you for your answer code777,

if( num > 1 ){
	
    while( str.length( ) < num ) {
        cout << "Enter text: ";
        getline( cin, str );
    }
	cout << "Text: " << str << '\n';
	

}
