    You can simply use single-quotes to make a character constant:

    char c = 'a';
    

    The character type is a numeric type, so there is no real need for asc and chr equivalents.

    Here's a small example that prints out the character values of a string:

    #include 
    
    int main(int argc, char **argv) {
      char str[] ="Hello, World!";
    
      printf("string = \"%s\"\n", str);
    
      printf("chars = ");
      for (int i=0; str[i] != 0; i++) 
        printf("%d ", str[i]);
      printf("\n");
    
      return 0;
    }
    

    The output is:

    string = "Hello, World!"
    chars = 72 101 108 108 111 44 32 87 111 114 108 100 33
