2.1 : The sizeof operator gives the number of bytes required to store a variable
      of the type. Write a program to find, sizeof an int, short, double, char, float,
      an array of 100 ints. Which library contains sizeof function? Be sure to
      include that.

2.2 : Write a program that will open a bmp file, read each byte and print the value
      of the byte as an unsigned int. Hint: use fread (see lecture 02)
      and stdio and stdlib

2.3 : write a program to read a file of words and count the words in the file.
      create your own file and test the program.

      int A[100];
      printf("%d %d %d %d %d %d \n", sizeof(int), sizeof(double), sizeof(long), sizeof(char)
                                     sizeof(float), sizeof(A));

      FILE* fp = fopen("image.bmp", "r");
      char buffer[10000]; /* assume image is 10000 bytes */
      fread(fp,10000,1,buffer);
      for (i=0; i<10000; i++)
        printf("%u ", buffer[i]);

2.3 : write a program to read a file of words and count the words in the file.
      create your own file and test the program.

       FILE* fp = fopen("file", "r");
       int i=0;
       char buf[50];
       while (fscanf(fp,"%s",buf)>0) i++;
       return i;
