Please advise?
I've never fully grasped scope/namespaces, but have been able to work around
earlier problems.
I now have a program flow situation in which I have *no choice* but to do
this this way.
Suppose I have something like;
var1=0.0;
main() {
/*do something sane*/
if (/*condition*/) {
var1=7.65347; //somenumber
}
//use var1's new value
}
How do I get a changed variable back out of an if statement's { } block?
I do math inside the if( ){ now, where before, the math was in the main()
function. I've now no choice: I'm skipping user entry IFF there's a file to
be read, with the same info in it that the user would have entered, so I
have to conditionalize many of the operations that otherwise were in the
main(){. )
I'm missing something simple I'm sure, and I _thought_ if I declared the
variable (initialized or not) outside of the main() function (hence global;
every loop should 'see' it no matter how nested), I could change it and it
would come back out changed, but I've had this same problem several times
now.
The 400+ line program compiles and runs, but my _info_ is gone 'cause it's
being calculated in an if( ){ instead of in the main(){ .
I'm frazzled. Please if there's a short/sweet way to spit the var back out
into the main(), let me know?
Thanks....
