OPTION C

[@cloudproblemssolved]

for printf, %f and %lf are both used for double, but this is a scanf function, so only %lf is used for doublem %f is for float, therefore I agree with the other comment, option c

[@fulchandsheikh4380]

the answer is option c. scanf("%lf", &input);

Just started learning programming for the first time and so far, so good. About the last quiz on the tutorial, double input is represented by %lf, hence the correct answer is ("%lf", &input);

[@annettewairimu5542]

option C is the correct answer. option A is for the int data type input, option B is for the float data type input, and option D is for the char data type input. Great content, amazing explanation.

[@sukanyamukherjee5475]

Answer to the question asked in the end of the video will be option C.

[@sezarefretamiguel3249]

I agree 100%d

[@LyricsVibe95]

But it is double input, the format specifier for double is %lf, so why do you go to %f? That's format specifier for float.

[@cloudproblemssolved]

@@LyricsVibe95 In scanf and related functions, %f is used for float and %lf is used for double

CODE TO ENTER INTEGER AND FLOAT VALUE AND SHOW OUTPUT:
#include
int main() {
int number;
float number1;
printf("Enter input values: ");
scanf("%d %f", &number, &number1);
printf("Number = %d", number);
printf("
Float = %f", number1);
return 0;
}
ANSWER TO THE QUIZ QUESTION:
Option C: scanf("%lf", &input)

[@eazyj_c]

Great tutorial. The correct way to take a double input is of answer C: scanf("%lf", &input); Thanks.

WAP to take integer and foat input from the user.
#include
int main(){
int number1;
float number2;
printf("Enter the input values: ");
scanf("%d %f", &number1, &number2);
printf("IntNum= %d,
FloatNum= %f",number1,number2);
//printf("
FloatNum= %f",number2);//

return 0;
}
Outpur:
number1: 20
number2: 20.35

[@nerd2544]

*I found this online and I don't know if it is mentioned in later chapters but it's very important so: (about reading char variables using scanf)*
"Quite often I see the following problem in people’s code ( as a matter of fact, aliens don’t do that mistake :p ), when trying to input a character again and again with scanf. Usually, this happens inside a loop, but let’s see a sample code without a loop that exposes the problem."
int main()
{
char c;

printf("Input No.1
");
scanf("%c", &c);
printf("c = %c
", c);

printf("Input No.2
");
scanf("%c", &c);
printf("c = %c
", c);

printf("Input No.3
");
scanf("%c", &c);
printf("c = %c
", c);

return 0;
}
"which gives output:"
Input No.1
s
c = s
Input No.2
c =

Input No.3
a
c = a
"As you see, the input No.2 was skipped. Well not really, not at all. But the intention of the programmer is usually to get three characters from the user, which is what is happening, isn’t? Let me explain. *Think what you do, when you input. First prompt message arrives, you type s and then what? You hit enter! Enter is a character!*
*As a result, first scanf will read the s. Second scanf will read the enter! That’s why, the second printf of the value of c leaves just a newline after “c=”. Then the third scanf waits for a key press. You input a and then you hit enter. a is been assigned to variable c and enter remains in the stdin buffer, ready to be read by the next scanf. If we had a fourth scanf, then it would read the enter.*
However, many would think now that, “Wait a minute… I do this while reading numbers, with %d for example and I had no problem”. Correct! Why? Because %d automatically eats whitespaces and special characters. Logical, isn’t it? Whitespaces and special characters are characters, not numbers! However, %c has to interpret whitespaces and special characters as inputs, because %c reads characters 😉 . Luckily enough, the “fix to scanf to do what you intend it to do” is to leave a space before %c. That way you say to scanf to automatically eat whitespaces and special characters, like enter! So, just change scanf(“%c”, &c); to scanf(” %c”, &c); and you will be just fine. See by yourself in the code below:"
int main(void)
{
char c;
/* FIX: Leave a space before %c */

printf("Input No.1
");
scanf("%c", &c);
printf("c = %c
", c);

printf("Input No.2
");
scanf(" %c", &c);
printf("c = %c
", c);

printf("Input No.3
");
scanf(" %c", &c);
printf("c = %c
", c);

return 0;
}
"which outputs, what you expect:"
Input No.1
s
c = s
Input No.2
a
c = a
Input No.3
m
c = m
"Notice that in the first scanf, there is no need for a space before %c, since it’s the first input function, thus there is no trailing newline to eat, as discussed in the comments section below my post."

[@saacademy6286]
