[Courses] C Programming For Absolute Beginners, Lesson 3: Else If, While, Operators

[Emily Gonyer]

//books you have

#include <stdio.h>

int main()
{
int book=0;
int book2=0;
int book3=0;

printf( "Please enter how many books you have.");
scanf( "%d", &book );
printf( "So, you have %d books.", book);

while ( book < 10 ){
printf( "Books are good! But is that all you have? Please enter how many
books you have.\n" );
scanf( "%d", &book );
printf( "OK, so you have %d books.", book);
}
if ( book > 50 ){
printf( "Awesome! I love books too!\n" );
}
else if ( book > 11 ){
printf( "Books are good! You can never have too many you know!\n" );
}
return 0;
}

Hey there, after much playing this is what I've come up with :)
