Thread: C program not outputting correctly

Hello, I have this program that asks the user to enter 10 characters. I store these characters in an array and sort them using a bubble sort. However, when I run it, it reads in the Enter key and the character both, but the Enter key is not suppose to be a character. How can I fix this? I am trying to learn C but I am struggling. If anyone is willing to help me I will greatly appreciate it

Code:

#include <stdio.h>
#include <stdbool.h>


void bubbleSort(char *);
int main(){
    char *arr=(char *)malloc(11*sizeof(char));
    int i;
    char input;




    for( i=0;i<10;i++, input = '\0'){


        printf("Enter character number %d:\n", i+1);


        scanf("%c", (arr+i));




    }






    bubbleSort(arr);


    printf("The sorted characters are:\n");
    for(i=0;i<10;i++){


        printf("%c ", *(arr+i));
    }


    printf("\n");
}


void bubbleSort(char *arr){
    char temp;
    bool swap;


    do{
        swap = false;
        int i;
        for( i = 0; i < 10; i++ )
        {
            if(*(arr + i)< *(arr + i + 1)){
                temp = *(arr + i);
                *(arr + i) = *(arr+ i +1 );
                *(arr+ i + 1) = temp;
                swap = true;


            }
        }


    }while(swap);




}

Oh thank you so much. I didn't know that, you're awesome
