Difference b/w cin.get and cin.getline

#1

why we have used cin.get and cin.getline different times if one is already used because i think both have same meaning.

#2

HI @jindaldivish
cin.getline() reads input up to ‘\n’ and stops

cin.get() reads input up to ‘\n’ and keeps ‘\n’ in the stream

For example :

char str1[100];
char str2[100];
cin.getline(str1 , 100);
cin.get(str2 , 100);
cout << str1 << " "<<str2;
input :
1 2
3 4
output 1 2 3 4 // the output expexted

When reverse them
For example :

char str1[100];
char str2[100];
cin.get(str2 , 100);
cin.getline(str1 , 100);
cout << str1 << " "<<str2;
input :
1 2
3 4
output 1 2 // the output unexpexted because cin.getline() read the ‘\n’

in your reply i didnt understand much that how can we enter integers as input despite character datatype.

#4

can you explain it in much clear way the difference between cin.get and cin.getline used in the video lecture.

@jindaldivish 1, 2, 3, 4 are integers but they can be used as characters as well, they have the ascii value from 48(0) to 57(9). Refer to this table http://www.asciitable.com/ to clarify what all characters are there.
If it helps you any better, think of a, b, c, d instead of 1,2,3,4 logic works the same.
You can read some more about input stream and buffer if you are confused because I dont think I can provide a more clear example than this.
