Truncate the char and clean the buffer.

[swaroop]

How can I use ignore() and truncate to take 20 char from user input in a name[40] variable.....

When I try to use

cin.get(name,20,'\n');
cin.getline(name,20,'\n');


cin.get(name,20,'\n').get();
cin.getline(name,20,'\n').get();

cin.get(name,20,'\n').ignore(20);
cin.getline(name,20,'\n').ignore(20);

It is not cleaning buffer in while loop.

Thanks in advance

Hi,
Do like the following, it will solv your problem.

#include <iostream.h>
int main()
{
char name[100];
while(1) // To terminate the loop press Ctrl C
{
cin.get(name, 20, '\r');
cout << name << endl;
cin.ignore(1000, '\n');
}
return 0;
}
