Complete an ANSI-C program, which should use getchar (only) to read and interpret integer.

Download the partially implemented file lab2D.c and start from there. The program:

• should use getchar() to read inputs (from standard in) until EOF is read. The input

  contains decimal integer literals separated by one blanks or new line characters. The program interprets each literal and put into an int array. When end of file is reached, the program prints out the value of each integer and the double of the value.

• assume all literals in the input are valid decimal int literals. Note that the input can contain negative numbers.

• should NOT use other input IO functions such as scanf(), fgets(). Only getChar() is allowed to read input. (So have to read char by char.)

• should NOT use other library function such as atoi() (So have to convert manually)
