output all combinations of character variables a, b, and C. If a-X. b-y and c = 'z, then the output is Your code will be tested in three different programs, with a, b, c assigned with X. 'y, 'z, then with #,'$','%, then with '1', 2, 3 1 #include 3 int main(void) char a; char b; char c; 4 scanf(" %c " scanf(" %c ", &b); scanf(" %c ", & ), 10 12 Your solution goes here 13 14 printf("In") 15 16 return 0
