too many arguments in function call in c?

Question

I'm trying to create a menu of colors but the last line reported some error.

puts("I don't know about the color %c",input);

Here's the declaration

char input[7];

And the initialization

scanf("%c",&input);

The error is here

Too many arguments in function call
error: expected declaration specifiers or '...' before '&' token
scanf("%c",&input);
        ^
error: expected declaration specifiers or '...' before string constant
scanf("%c",&input);
   ^~~~

Why is it?

Answer 1

For starters this call

scanf("%c",&input);
      ^^^ ^^^

is incorrect. You have to write

scanf("%s", input);
      ^^^  ^^^

As for the error message then the function puts accepts only one argument. It seems you mean the function printf instead of puts. And the format specifier shall be %s instead of %c if you are going to output a whole string.

printf("I don't know about the color %s",input);
                                     ^^^

Otherwise if you was going to input only one character instead of a string then you need to write

scanf("%c",input);

and

printf("I don't know about the color %c\n",input[0]);
