Thread: 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");
		}

%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....

Code:

 
    I tried this also, but it didn't work......Any answers.?





      char x;
	
	int c; 


       printf("\nEnter a to sort in ascending order.\n");
	printf("Enter d to sort in descending order.\n");
  	
	{
           scanf("%s",&c);}
   
		
		if (c == 'a'){
		bubble(a, SIZE, ascending);
		printf("\nNumbers in ascending order.\n");
		}
		else{
		bubble(a,SIZE,descending);
		printf( "\nNumb

Try reading the answer again.

It goes straight to descending order when I input a..Instead of descending order.Maybe a problem further into program?

Nevermind, I got it......Thanks for your help bro.

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