how is it different from cin?

Hey @Shreya-Gupta-2383169445069382
cin.get() is different from cin() because cin.get() reads a string with the whitespace.
Syntax:
cin.get(string_name, size);

eg:

#include
using namespace std;

int main()
{
char name[25];
cin.get(name, 25);
cout << name;

return 0;

}
Input:
Geeks for Geeks
Output:
Geeks for Geeks

while in case of cin:
#include
using namespace std;

int main()
{
char name[25];
cin >> name;
cout << name;

return 0;

}

Input:
Geeks for Geeks
Output:
Geeks

Whats the use of cin. Get without parameters

@Shreya-Gupta-2383169445069382
The cin.get() member function with no arguments returns the next character from the input. That is you use it in this way:
ch = cin.get();

For example:
#include
using namespace std;
int main()
{
char ch;
while ( (ch = cin.get()) != EOF)
{
cout << "ch: " << ch << endl;
}
cout << “\nDone!\n”;
return 0;
}
This program reads a file character by character until EOF(end of file) is encountered.

“helloWorld”
if you want to take input character by character using cin, you won’t be able to do it
cin would keep reading until it encounters a space, so essentially cin reads word-by-word.
However, you could use cin.get() to read character-by-character

cin.get() by default (no parameters) returns one character but you can parse paramters into it as you wish

you could do c = cin.get(); it’ll save the next char into variable c, the char could even be a whitespace
cin.get() method doesn’t stop at the white space unlike the normal cin

you could do cin.get( c ) to achieve the same thing as above

you can also read a char array of particular size with cin.get() as follows:
char carr[10];
cin.get(carr, 3);
this will read only 2 chars, in general cin.get(carr, n) reads n-1 chars
