How can I get only the first character entered by the user?

Hangman

I'm using scanf to get a character entered by the user (guessed letter), but it seems like scanf gets all the letters entered

        char guessed_letter;
        printf("\n");

        scanf(" %c", &guessed_letter);

enter image description here

if the word is moon

if the user entered moo this happens

m _ _ _

m o _ _

m o o _

but what I'm expecting is to read only the first one.

m _ _ _

this problem aslo occures when counting mistakes because it scans more than one charachter

I'm scanning for the letter in a do while loop, because I want the user to keep guessing

this code will work for you. first of all you take the whole word from the user. because the users want to write whole word not a just character. (by the way if you don't want to deal with the "malloc", you can use the strdup. but i suggest learn to the malloc.) The first letter of the character from the user is the value you want. you can write it by its first index (guessed_letter[0]).

#include <stdio.h>
#include <string.h>
int main()
{
    char *guessed_letter = strdup("");
    printf("\n");
    scanf("%s", guessed_letter);
    printf("first character is: %c", guessed_letter[0]);


}
