00:00Hello everyone. Today I'm going to explain get care and the put care methods or you can

00:10say the get care and put care functions. We have used in our program the scanf and the

00:18printf function and we know that the scanf function is to read the value from the keyboard,

00:26to read the data from the keyboard and the printf function is used to display the data

00:32on the screen, to display the values on the screen. In the same way the get care and the

00:38put care function works, if we have to read the characters, so reading a character that

00:45can be done with the help of the get care. We can use scanf also but if we have to only

00:54read a single character then in spite of using scanf we can use the get care and if we have

01:00to write the character on the screen or you have to display the character on the screen

01:05then there is what put care method or you can say the put care function. So writing

01:10a character on the screen that can be done by the using of put care. So I'm going to

01:16explain the programs of it, first of all I'm going to explain the program of get care and

01:23then I'm going to explain the program of put care. Let me open the program, that of get care.

01:35So this is the program of get care and it's a very simple program and the program is to

01:49input the value from the keyboard and on the basis of value it's going to display a message.

01:58So here if you see I have taken one of the variable a, inside the printf I have written

02:04a statement that is a message that is to input y for yes and n for no. Now when I input a

02:13single character that character will be read by the function get care and this function

02:20is going to store the character value inside the variable a. If I input a character value

02:31y in uppercase or in a lowercase either in a capital letter or in a small letter then

02:43the statement is going to satisfy. If the value of a is capital Y or if the value of

02:50a is small y so it's going to compare with the constants y. So if suppose I have input

02:59inside a a capital Y so capital Y equal equal to capital Y here the condition is true or if

03:07suppose I store the value of a small y then small y equal equal to small y here the condition is

03:14true. So if any one of the condition gets true the statement is going to display, this message

03:20is going to display and if I input any other alphabet suppose I input n for no either in

03:33small or a capital that value is going to store inside a. So this both the condition get false

03:38so it will come to the else part and it's going to display what to buy. So let me run the program

03:45and see is it going to work or not. First of all let us compile and see if there is any error.

03:51So it's not showing any error. If for this console window if it's not display so what you can do

04:07you can go to the view and here it shows what logs or you can press the F2 key so it's going

04:13to show you the console window. So it's showing what zero error zero warning. So there is no

04:20error in the program. Let me run the program. Now it's asking me to input the value when I

04:25press Y and press enter it's showing me welcome. One of the condition is fulfilled and if I again

04:34run the program and suppose if I input n in a capital letter and I press enter key so this

04:43condition gets false the statement ends display y. So this is the program of get care and with

04:54the help of get care function the operation is performed and we get the result. Now I'm

05:03going to explain the program of put care. This is the program of it. The program is very simple

05:19that I have to input one of the alphabet from the keyboard and if the alphabet which I input

05:26the character which I input that is in small letters then it's going to display in a capital

05:32letter and if it's in a capital letter then it's going to display in a small letters. So I have

05:40taken out the variable a one message is going to display to enter any alphabet. So with the help

05:46of get care function I am going to put the value a single character from the keyboard that is going

05:53to store inside a. Here is one of the predefined function is lower okay that will convert if the

06:04value it will take the value if it is lower then it's going to convert to upper and it's going to

06:17display and if the values is not lower so it's going to come to the else part and with the help

06:24of to lower it's going to convert into lower okay that is in small letters. So if the condition is

06:33true that is the if the alphabet which you have input that is in is lower that is in small letter

06:41that alphabet then with the help of to upper it's going to convert into capital letter okay and going

06:48to display on the screen with the help of put care function and suppose if you have input the alphabet

06:54in a capital letter so this condition will get false and it will come to the else part and with

06:59the help of put care function it's going to convert into small letter and going to display. So will

07:07this happen or not let us see I'm going to run the program. I'm going to store I'm going to input

07:15the value in a capital letter a and I press enter it should mean a small letter okay the a in a

07:23lowercase and if I again run the program and this time I input the alphabet in a small letter and

07:34I press the enter key it's converted into capital letter that is in uppercase okay.

07:40So I hope you understand how to use the get care and the put care function. Thank you.
