Hello
Im learning c at the moment and run into a problem. Would be great if someone could help me as its a very basic problem.

Im trying to write 10 strings (got from scanf) in a 2 dimensional array of char:

C++

char wortListe[10][10];

				for ( y=0;y<10;y++)
			{
				for ( i=0;i<10;i++)
				{
					scanf_s("%c",&wortListe[i][y]);
				}
				
			}

and read it out with

C++

while ( i<10 )
			{
				while ( y<10 )
				{
					printf_s("%c",wortListe[i][y]);	
					y++;
				}
				i++;
			}
			break;

but its not working for some reasons. Normaly im doing everything i need with delphi so would be great if someone could point at the errors ive made :)

What is "not working", exactly? What are initial values of i and y in the second code fragment? show the line when they are declared/initialized. Do you share the same i and y objects in both code fragments?
Did you use the debugger?

Please, can you post what the above code is printing? Any errors, warnings during Build?

See http://www.cplusplus.com/reference/cstdio/scanf/[^]. The description for the format specifier c states that:

The next character. If a width other than 1 is specified, the function reads exactly width characters and stores them in the successive locations of the array passed as argument.

(Emphasis added)

In other words, rather than passing a variable (or array element) of type char, you should pass a variable of type array of char to scanf, like this:

C++

scanf("%c", wortliste[i]+y);

Of course, you might as well replace the inner loop by reading all 10 characters at once, using the width specifier:

C++

scanf("%10c", wortliste[i]);

Solution 1

you are using the wrong identifier for the job: use "%s"

scanf_s("%s",wortListe[i]);

printf_s("%s",wortListe[i]);
