A very simple doubt

[afser]

Hi,

Im unable to to read and print the 2nd char in the following code. please help.it is not taking the 2nd input from the keyboard. I know that it is taking the new line char from the buffer instead of giving an option to enter another char. I tried using scanf, still the same prob. i tried fflush, it didnt work. please help me to solve this problem.

input :a

output: ch1=a
ch2=

#include<stdio.h>
int main()
{
    char ch1,ch2;
    ch1=getchar();
    printf("ch1=%c\n",ch1);
    ch2=getchar();
    printf("ch2=%c\n",ch2);
}

getchar will take whatever character is in the buffer, enter-key or no.

If you want scanf to skip "whitespace" characters (space, tab, enter-key), then you have to put that in your format specifier:

scanf(" %c", &ch1);

thank you.

But i want to do it using getchar option. Is is possible? if yes then how?

getchar will read in \n when it is typed. You can check: if the result of the getchar is \n, read in another character.

How are you typing the input characters. Is it a character followed by newline followed by another character?
If that's the case then ch2 will contain newline. Instead type one character followed by another w/o interleaving whitespace.

Character followed by a newline. actually ch1 and ch2 in my actual code come at two different places in a 400 line code.So i need to enter new line and be able to get the next char to be accepted. I need the following to happen:

input:
a followed by newline
b followed by newline

output:
ch1=a
ch2=b

please provide me with the code as it would be really helpful.

thank you.

In that case all you need to do is to loop while reading from stdin while sifting out the whitespace or have three instances of getchar().

Sorry, im a beginner in c. Can you please provide me with the code for shifting the white spaces. sorry again.
