c++ - what is faster ?
- by VaioIsBorn
If we have the following 2 snippets of code in c++ that do the same task:
int a, b=somenumber;
while(b > 0)
{
a = b % 3;
b /= 3;
}
or
int b=somenumber;
while(b > 0)
{
int a=b%3;
b /= 3;
}
I don't know much about computer architecture/c++ design, but i think that the first code is faster because it declares the integer a at the beginning and just uses it in the while-loop, and in the second code the integer a is being declared everytime the while-loop starts over. Can some one help me with this, am i correct or what and why ?
