| return |
|
grammar |
| |
A directive that stops execution in the current context and
supplies back to the parent context the value of the associated expression,
if supplied.
When called from the topmost context, the interpreter will be exited, but
unlike an explicit
exit
call, no
low order bits are supplied to the parent process of the interpreter.
Its usage description can be summarized as follows:
Statement:
return ExpressionOPT ;

| Example: |
The following example uses
return
in a function to provide a pseudo-random number uniformly distributed
between 0 and 100 to the parent.
import yoix.stdio.printf;
u100() {
int r;
do {
r = 101.0 * yoix.math.random();
} while(r == 101);
return(r);
}
int r1 = u100();
int r2 = u100();
int r3 = u100();
printf("r1=%d, r2=%d, r3=%d\n", r1, r2, r3);
An sample of some output is:
r1=42, r2=96, r3=10
