C program idea not sure!

Here is an idea that I thought was pretty cool.

I just got a book on C, never really coded anything but I want the program to do the following

I want it to calculate the age of an actor when a specific movie was released

For example

Input would be

Zodiac Signs

Actor name = Al Pacino

Actor Bday = 04/23/1940

Film Name = God Father

Film Release Date = 1972

OUTPUT:

When Al Pacino filmed "The Godfather" he was "32" years old, Al Pacino is currently 68 years old and is a "Taurus" The Godfather was made "36" years ago

Can someone show me how this would work or atleast get me started. Thanks

I know this is wrong but this is a basic structure I thought of

#include <stdio.h>
int main(void)
{
float actorname;
float filmname;
int bday;
int releaseyear;
int age
int filmage;

printf("What is the actors name?"\n);
scanf("%s", actorname);
printf("What is the film name?"\n);
scanf("%s", filmname);
printf("What is the actors birthday?"\n);
scanf("%s", bday);
printf("What is the films release year"\n);
scanf("%s", releaseyear);

bday - 2008 = age
filmrelease - 2008 = filmage


printf("When %s, actorname filmed %s, filmname he was %sage, years old. %s, actorname is currently %age, and he is a Zodiac sIGN, %sfilmname was made %s, filmage)


}

}

You should pick up a book on Beginning C, and start with that. There is almost
nothing right about your prototype program (even using code tags for the forum
has eluded you).

e.g.:
1) Actor's name and film name are not floats, they're letters (char's), and go into
arrays of

Code:

char: actors_name[40];
scanf("%s", actors_name);

2) bday - 2008 will not give you a correct age. It will give you a negative number,
so swap them around. Same with filmage.

What would be grand for your program is if you had the data in a file which was
loaded into an array on start up. The data file would have the moves, the bday
for each actor, the year the film was made, etc.

Very few people will know the birthday of movie stars, or the year a film came out,
once it gets past about five years. This would make your program much more
challenging, but also, much more valuable.

To use code tags, just highlight your program, and then click on the # char in the
message window.

Thanks for your input but the idea is that the person types in all the info, like searching wikipedia or IMDB and the program calculates their age at the time of the movie being released.

Code:

	
printf("When %s, actorname filmed %s, filmname 
 he was %sage, years old. %s, actorname is currently
 %age, and he is a Zodiac sIGN, %sfilmname was made %s, filmage)

Printf isn't used like that. It is used in a similar way as scanf. You should:

Code:

printf("blah blah %s blah blah %s", actorname, filmname);

The actorname is printed instead of the first %s, the filmname instead of the second %s etc.
Another thing you don't understand probably is that you don't use the %s for everything. If you want to have a number you should use the %d, that is for integers.

Code:

        printf("What is the actors birthday?"\n);
	scanf("%d", bday);

And at last, I suppose you didn't compile the program. Start a little by little. One thing, compile, run. Another thing, compile, run. This way you will learn step by step what you do wrong and what not. The compiler errors will help you

Take a while and read up on what you should not do with scanf.
http://cpwiki.sourceforge.net/Common...kes_and_errors

I don't think anyone's mentioned yet that newlines (\n) should be inside the double-quoted string literals, like so:

Code:

printf("Hello, World!\n");

Code:

scanf("%d", bday);

Note, of course, that you'd need to use &bday. You need an & before every variable read with scanf(), except for strings.
