yadi and natra

yadi means “if” and natra means “otherwise”.

rakha umer = 20;

yadi (umer > 17) {
  bhana("Voting garna milchha.");
} natra {
  bhana("Ajhai sano.");
}

Voting garna milchha.

The condition goes in parentheses, and each block goes in braces. natra is optional.

More than two choices

Put another yadi inside the natra block:

rakha ank = 72;

yadi (ank > 79) {
  bhana("Distinction");
} natra {
  yadi (ank > 59) {
    bhana("First division");
  } natra {
    bhana("Pass");
  }
}

First division

yadi gives back a value

A yadi is an expression: it produces the value of the last line in the block that ran. You can store that value.

rakha a = 8;
rakha b = 13;
rakha thulo = yadi (a > b) { a; } natra { b; };

bhana("Thulo:", thulo);

Thulo: 13

If the condition is false and there is no natra, the result is khali.

No semicolon after the brace

A yadi statement ends with }, so it does not need a ; after it. Adding one is allowed.
