    please help, quick question.

    Code:
    How do I get the scanf statement to read a character from user input?.A for ascending and D for descending.....It doesn't error but its not working properly.......Is there something wrong with my if statement maybe?
    
    Thanks for any help.
    
    
            char x[1];
    	
    	int c; 
    
    
           printf("\nEnter a to sort in ascending order.\n");
    	printf("Enter d to sort in descending order.\n");
      	
    	for(c = 1; c <= 1; c++){
               scanf("%s",&x[c]);}
       
    		
    		if (x[c] == 'a'){
    		bubble(a, SIZE, ascending);
    		printf("\nNumbers in ascending order.\n");
    		}
    		else{
    		bubble(a,SIZE,descending);
    		printf( "\nNumbers in descending order.\n");
    		}

    &#37;c reads in a single character.

    Note that in your example, x[1] does not exist despite your attempts to read into it.

    Edit: Which of course then brings up the question of why you have an array at all....

    Try reading the answer again. And also note that "int c" is not the same as "char c".
