The first exercise of mine:/* Write a C-program to print the vaue of
the alphabet when an integet value is entered .. For example if 1 is
entered then A must be printed on the screen,if 2 is printed then B
must be printed...like this so on......*/

Do you have a question?

Hints:

const char array[] = "Hello";

printf("%c\n", array[0]);
printf("%c\n", array[1]);

printf("%d\n", 0 + 1);

What a dumb exercise. You need to throw away the material from which
you got that exercise and buy a good C text like K&R2.

Most newbie exercises are fairly dumb. I don't see any particular
objection to this one.

It tempts the newbie to assume that the character encoding is in
alphabetical order.

It tempts the newbie to assume that the character encoding is in
alphabetical order.

On the contrary, it demonstrates how to avoid such (erroneous)
assumptions.

 

[Eric Sosman]

It tempts the newbie to assume that the character encoding is in
alphabetical order.

... and offers an learning opportunity in overturning the
tempting assumption.

Temptation need not be a bad thing; read "The Man That
Corrupted Hadleyburg."

I don't see how. There is such a thing as alphabetical order, and
mapping that to integers seems natural. It doesn't say anything about
the order of alpha characters in the particular character encoding used.

If the student solved the problem in a way that used ASCII or
something, then they should be marked down for a non-portable solution.
There is a fairly straight-forward method that achieves it portably.

You probably mean: "Enter an integet...".

rc = scanf("%d", &integet_value);
while (rc == 1 && integet_value > 0 && 27 > integet_value) {
printf("The number %d letter of the alphabet is %c.\n\n",
integet_value,

I try to be careful, but sometimes I slip up.
