PTA: Use function to delete characters in the string (10 points) (C language)

Enter a positive integer repeat (0 <repeat <10), these times do repeat operations:

Enter a string str, and then enter a character c, c all the characters appearing in the string str deleted.

And calls the function defined in claim delchar (str, c), its function is to remove all characters in the string str c occurred, the type of the function parameter is a character pointer str, parameter c is of type char, is a function of the type of void .

Example O: described in brackets, without O

Sample input:
. 3 (REPEAT =. 3)
Happy new new year (character string "Happy new new year")
A (to be deleted character 'A')
Bee (string "Bee")
E (to be deleted character 'e')
111211 (character string "111211")
1 (a character to be deleted '1')

Output Sample:
Result: hppy new new YER (string "happy new year" in the character 'a' are removed)
Result: B (character string "bee" of the character 'e' are removed)
Result: 2 ( the string "111 211" in the character '1' are deleted)
