Thread: If else statements

I am currently coding a small program to comment on your age, and I am having problems with if else statements.

Code:

#include <iostream>

using namespace std;

int main()
{
 int age;

 cout<<"Please enter your age: \n";
 cin>> age;
 cin.ignore();

 if ( age <= 1 ) {
    cout<<"You are a baby!\n";
    }

 else if ( age <= 3 and > 1 ) {
      cout<<"You are a toddler.\n";
      }

 else else if ( age <= 12 and > 3 ) {
      cout<<"You are a child.\n";
      }

 else else else if ( age < 18 and > 12 ) {
      cout<<"You are a teenager.\n";
      }

 else else else else if ( age >= 18 and < 45 ) {
      cout<<"You are an adult.\n";
      }

 else else else else else if ( age >= 45 and <= 55) {
      cout<<"You are middle aged.\n";
      }

 else {
      cout<<"You are old!\n";
      {

 cin.get();
}

As you can see, i add and extra else everytime. This doesn't work, so i was wondering what i need to do to make this work.

is that all id need to change?

you would need a loop to do that, wouldnt you?

>> not "and"

Actually, "and" is legal. However, it would probably be wise to use "&&" instead so that programmers who are not familiar with that information are not confused by the code.

Due to the nature of the if-else structure, you don't actually need to check
"else If age is between 1 and 3" ...
"else if age is between 3 and 12"...
"else if age is between 12 and 18"... etc

the following would work in exactly the same way, and looks a bit neater:

"if age is less than 1"...
"else if age is less than 3"...
"else if age is less than 12"...
"else if age is less than 18"...

The reason for this - All the conditions are evaluated in order. "else..." does not get executed when "if" yeilds true, so, the entire if/else block terminates as soon as one of the conditions is matched.

so they are done in order? But also, how would i check to see if the entered age is below 0, and dispose of it if it is?

Put if age < 0 as the first in the if-else chain

and then if it is less than 0 go back to where it asks for the age?

'and" is not recognised by the compiler. you use &&(ampersand) or ||(or) .. && means the word and in english and || is or.. so to make it possible use || because && is only limited it the 1st condition is true then the second it false it is false...

joseph that information is solely dependent on your compiler, as my compiler recognizes the words and, or, not, but also uses &&, ||, !. Although I would reccomend using the symbols not the words 1) so other compilers are sure to be able to use it, 2) it isnt as confusing

Actually, as I already mentioned "and" is legal and all standards compliant compilers must recognize it as an alternate keyword for &&.
