    Need help (do while)

    Here is a code not working because of "do" command

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    int main()
    {
        int count_a = 0, count_e = 0, count_o = 0, count_i = 0, count_u = 0;
        char ch;
        do
        {
            ch = getche();
            switch (ch)
            {
            case'a':count_a++;
                break;
            case'e':count_e++;
                 break;
            case'o':count_o++;
                break;
         case'i':count_i++;
             break;
         case'u':count_u++;
                break;
        }
            printf("\n a exist %d times", count_a);
            printf("\n e exist %d times", count_e);
            printf("\n o exist %d times", count_o);
            printf("\n i exist %d times", count_i);
            printf("\n u exist %d times", count_u);
    }
    Please what's wrong why I can't compile it ?
    I'm using codeblocks and microsoft visual 2015. Thank you.
    and please don't answer like open a book and read again.. thanks

    You should post the compiler errors you recieve.

    Well, if you did, you would see that "do" requires a corresponding "while", which is not present in your code.

    No can do. This is very basic stuff that you need to work out on your own, if you're ever going to learn the language.

    If you did open a book (or find a tutorial), you would see at least one working example that can easily be applied to your program.

    Found a mistake
    Code:
    Thanks I found the mistake. #include <stdio.h>#include <stdlib.h>
    #define test 10
    int main()
    
    
    {
    	int count_a = 0, count_e = 0, count_o = 0, count_i = 0, count_u = 0, i = 0;
    	char ch;
    
    
    	do
    	{
    		ch = getche();
    		switch (ch)
    		{
    		case'a':count_a++;
    			break;
    		case'e':count_e++;
    			break;
    		case'o':count_o++;
    			break;
    		case'i':count_i++;
    			break;
    		case'u':count_u++;
    			break;
    		}
    	} while (ch!='.');
    
    
    		printf("\n a exist %d times", count_a);
    		printf("\n e exist %d times", count_e);
    		printf("\n o exist %d times", count_o);
    		printf("\n i exist %d times", count_i);
    		printf("\n u exist %d times", count_u);
    	}

    You're on the right track. What exactly is the mistake? You should describe the problem(s) you are having clearly.

    Note that "getche" is non-standard, consider using "getchar()" instead (and making "ch" an int: FAQ).
