code not taking 2nd character input

[kalu]

My code below is supposed to take 3 inputs, first 2 characters and 3rd floating. It just takes first input and ignores the 2nd. Here is the output I get.

Enter first character ? A
Enter second character ? Enter real value ? U
First character is: A
Second character is:

Real value is: 3.765E-039
Integer value is: 50

Here is the actual code. Please guide me where I am making a mistake.

#include <stdio.h>
#include <conio.h>

int main (int)

{

char ch1,ch2;
float x;
int n;

printf ("Enter first character ? ");
scanf ("%c", &ch1);
printf ("Enter second character ? ");
scanf ("%c", &ch2);
printf ("Enter real value ? ");
scanf ("%f", &x);

n = 50;

printf("First character is: %c \n",ch1);
printf("Second character is: %c \n",ch2);
printf("Real value is: %.3E \n",x);
printf("Integer value is: %d \n",n);

getch();
return 0;

    }

** btw, I am using dev c++ compiler.

Insert a space before %c within the second scanf( ).

Just for the record, Dev-C++ isn't a compiler. Dev-C++ uses the MinGW compiler.

Thank you for clarifying and also for correcting my code. It worked after adding a space. May I ask why it would only be required for the 2nd character. First character input works without the space.

[zb0S216C]

Allow me to elaborate. Before inserting the space, the entered characters were stored into the input buffer, which would've looked like this:

Input Buffer (before inserting a space): 'a', '\n'

When the input buffer is read, it's read as if it's a word, not two independent characters. However, after inserting the space, your input buffer would've looked like this:

Input Buffer (after inserting a space): 'a', '\n', ' ', 'b'

The space basically separated the two characters, which no longer resembles a word.

So, when scanf( ) saw the '\n' within your input buffer (after pressing enter), it used that escape sequence as the value for your second input (ch2), hence the skip.

You are inspiring for a wanna be coder. Thanks again Wazzak.
