Understanding scanf

i have looked through other scanf posts but i cant seem to find the issue i have here with this short code. The thing is when i enter a b or c, it doesnt go to the if or else if statements, i cant really figure out how to fix it, any help would be lovely! thank you!

#include <stdio.h>

int main(void)

{

char bogstav, a, b, c;

printf("Indtast a b eller c\n");
scanf("%c", &bogstav);

    if(bogstav == a)
    {
    printf("Du valgte a");
    }
        else if(bogstav == b)
        {
        printf("Du valgte b");
        }
            else if(bogstav == c)
            {
            printf("Du valgte c");
            }
                else
                {
                printf("Du valgte ikke a b eller c!");
                }
return 0;
}

two ways you can do it by declaring varriable

char a='a',b='b',c='c';

or

without declaring varriable check directly in condition like below

if(bogstav == 'a')
{ // do your stuff }

The problem in your code is that you want to compare bogstav to the value of the c character, not of the c value, but you're doing it in the other way :P

Just do if ( bogstav == 'b' ) to check if bogstav is equal to the b characcter.

#include <stdio.h>

int main(void)

{

char bogstav;

printf("Indtast a b eller c\n");
scanf("%c", &bogstav);

    if(bogstav == 'a')
    {
    printf("Du valgte a");
    }
        else if(bogstav == 'b')
        {
        printf("Du valgte b");
        }
            else if(bogstav == 'c')
            {
            printf("Du valgte c");
            }
                else
                {
                printf("Du valgte ikke a b eller c!");
                }
return 0;
}

a, b and c in the if statements are not characters, they are variables, which have not been initialized. You want to compare to 'a', etc. Or do char a = 'a';... , but that's probably overkill.

Are you expecting those to be literal characters?

if(bogstav == 'a')

You should initialize your variables a, b and c.
