left-hand operand of comma has no effect?

Question

I\'m having some trouble with this warning message, it is implemented within a template container class

int k = 0, l = 0;
    for ( k =(index+1), l=0; k <         


        

Answer 1

Change to:

for ( k =(index+1), l=0; k < sizeC && l < (sizeC-index); k++,l++){

When you have a comma expression is evaluated the rightmost argument is returned so your:

 k < sizeC, l < (sizeC-index)

expression evaluates to:

 l < (sizeC-index)

and thus misses

 k < sizeC

use the && to combine the conditions instead.
