Thread: is this what we should start with?

I got the idea from a source in the projects part of website so thought id try it on my own.

Code:

#include <stdio.h>
#include <string.h>

int main()
{
    int age;
    char name[3];
    
    printf( "Enter name of animal: " );
    scanf( "%s", name );
    if ( strcmp( name, "dog" ) == 0) {
         printf( "ok, its a dog\n");
         printf( "enter age: " ); 
         scanf( "%d", &age );
         age *= 7;
         printf( "your dog is %d in doggy years heh\n", age ); }
         else if (strcmp(name, "cat" ) == 0) {
              printf ( "ok its a cat\n" );
              printf ( "enter age: " );
              scanf( "%d", &age );
              age *= 7;
              printf( "your cat is %d in cat years\n", age); }
         
         getchar();
         getchar();
         return 0;
         }

it works fine, is this the easiest way to right it or is there a different way?

but anyway, is this ok for my first tinyyyyyyy program?

reece.

ok thanks for the tip. yeh i tried putting the age *= 7 at the top and bottom, middle everything and it wouldnt work for them both lol, didnt think of doing the

Code:

 printf( "your "%s" is "%d" is %s" years old\n" name, age, name );

works fine when run though so im happy with it considering its my first try at something from a blank page

thanks. reece.

last thing, any ideas on a simple program like this that i shud try to do to get me going?

bah, fixed it.

this works perfect.

Code:

#include <stdio.h>
#include <string.h>

int main()
{
    int age;
    char name[3];
    
    printf( "Enter name of animal: " );
    scanf( "%s", name );
    if ( strcmp( name, "dog" ) == 0) {
         printf( "ok, its a dog\n");
         printf( "enter age: " ); 
         scanf( "%d", &age );}
         else if (strcmp(name, "cat" ) == 0) {
              printf ( "ok its a cat\n" );
              printf ( "enter age: " );
              scanf( "%d", &age );}{
              age *= 7;
              printf("your %s is %d is %s years old\n", name, age, name );
         getchar();
         getchar();
         getchar();
         return 0;
}
}

any ideas of other small programs to start with?

any u first tried?

Code:

char name[3];

Name needs at least four elements to accomadate the NULL terminator placed at the end of strings.
This program could also be compacted a little more:

Code:

#include <stdio.h>
#include <string.h>

int main()
{
    int age;
    char name[4];
    
    printf( "Enter name of animal: " );
    scanf( "%s", name );
    if (!strcmp(name, "dog") || !strcmp(name, "cat")) 
   {
         printf( "ok, its a %s\n", name);
         printf( "enter age: " ); 
         scanf( "%d", &age );
         printf("your %s is %d years old which is %d in human years\n", name, age, age*7);
	
   }
   else
      printf("I've never heard of a %s\n", name);
              
    getchar();
    getchar();
    getchar();
       
	return 0;

}

Next you could try to create a simple database program that asks the user to enter records and allows him get information for a record.

ok ill try a database program, any chance youv got a small piece of code from one that i can check out? :-D or the tutorials for them?

one where you enter a name, then last name and then age and it stores it. or you can look some up.

and even when uve closed it, if u re open the program u can search for what u entered.

?

First you would need to define the structure of each record for example

Code:

typedef struct Record
{
   char FirstName[20];
   char LastName[20];
   int Age;
};

It is best to split your program into seperate functions, you could create functions for loading (using fread() ), saving (using fwrite() )and searching (using strcmp/strcmpi to search by first or last name)
