C++ Lookup of i changed for ISO

Question

I have the following code for a dictionary.

void Dictionary::translate(char out_s[], const char s[])
{

for (int i=0;i

        

Answer 1

When you do e.g.

for (int i=0;i

then the variable i is local to the loop only, you can't really use it outside the loop.

If you want to use i outside the loop, then you need to declare it outside the loop:

int i;
for (i=0;i
