Question

as you could see in the title, I am working on a vector of structs.

one of the struct members is string word.
when i am trying to enter data to this member in this way: (*iv).word=temp_str;, i get a runtime error.

while (is!=str1.end())
{
    if (((*is)!='-')&&((*is)!='.')&&((*is)!=',')&&((*is)!=';')&&((*is)!='?')&&((*is)!='!')&&((*is)!=':'))
    {
        temp_str.push_back(*is);
        ++is;
    }
    else
    {        
        (*iv).word=temp_str;
        ++iv;
        str1.erase(is);
        temp_str.clear();
    }
}

this may be the relevant code interval.

should say- word and temp_str are of string type.
iv is an iterator to the vector.

what is the right way to enter data into a struct member in this case?

Answer 1

Your iterator is probably invalid, otherwise it shouldn’t be a problem assigning one string to another.

One problem is the line:

str1.erase(is);

This will invalidate is, you should probably change it to:

is = str1.erase(is);

What does iv point at? It seems like you would need to add something like:

while (is!=str1.end() && iv != something.end())

as well.
