Q:

Point out the error, if any, in the following program.

#include "stdio.h"

main()

{

      unsigned char;

       FILE *fp;

       fp = fopen ("trail", "r");

       while (( ch = getc (fp)) ! = EOF)

               printf ("%c", ch);

       fclose (fp);

}  

Answer

EOF has been defined as #define EOF -1 n the file "stdio.h" and an unsigned char ranges from 0 to 255 hence when EOF is read from the file it cannot be accommodated in ch. Solution is to declare ch as an int.

Q:

What is the term used in tennis when the score is 40-40?

A) Ace B) Led
C) Deuce D) Tie
 
Answer & Explanation Answer: C) Deuce

Explanation:

When both sides have won the same number of points then: when each side has won one, or two, points, the score is described as "15-all" and "30-all" (or "15-up" and "30-up"), respectively.

However, if each player has won three points, the score is called as "deuce", not "40–all". From that point on in the game, whenever the score is tied, it is described as "deuce", regardless of how many points have been played.
