incrementation dans for-loop

[sanctus]

what is the difference between

for(j=0;j<cl.ts[0]->size();++j){
double l=cmbcalc->j2l[j];
}
 

and

for(j=0;j<cl.ts[0]->size();j++){
double l=cmbcalc->j2l[j];
}
 

?

I know that usually it means when the incrementation is made, in the sense that

 
x=10;
y=++x;
 

gives x=10 and y=11
while

x=10;
y=x++;
 

gives x=10=y. But what does it change in a for-loop?

Nothing, the 2 for loop implementations are functionally identical. It would only have an effect if the e3rd expresion in the for loop where more complex such that it was dependent, as an expression, on j being pre or post incremented.

thanks very much for your help.
