why I'm not getting the right values

[ysf007]

Hey,

I've a map that I set on it these values

    map<string, size_t>::iterator it;

    for ( it = indexBin.begin(); it != indexBin.end(); it++ )
    {
        std::cout << it->first  // string (key)
                  << ':'
                  << it->second   // string's value
                  << std::endl ;
    }

file0_first_.bin:8
file0_second_.bin:15
file1_first_.bin:8
file1_second_.bin:15
file2_first_.bin:8
file2_second_.bin:9
file3_first_.bin:8
file3_second_.bin:15
file4_first_.bin:8
file4_second_.bin:15
file5_first_.bin:8
file5_second_.bin:9
file6_first_.bin:8
file6_second_.bin:9
file7_first_.bin:8
file7_second_.bin:9
file8_first_.bin:8
file8_second_.bin:15
file9_first_.bin:8
file9_second_.bin:15

map has unique keys. so when I try to access by key using find

cout << indexBin.find(Name.c_str())->first <<" / "<<indexBin.find(Name.c_str())->second << endl;

I got nothing.

can somebody explain

What is Name? Are you sure it matches one of the keys exactly. No extra spaces? No difference in letter case?

It's usually a good idea to check that find was successful before trying to access the key-value pair.

auto it = indexBin.find(Name)
if (it != indexBin.end())
{
	cout << it->first << " / " << it->second << endl;
}
else
{
	cout << "No key \"" << Name << "\" found in map" << endl;
}

Name string containing bin name it changes while I loop over these bin files
yes I sure keys matches exactly

I forgot to add the extention, error of beginners

indexBin.find(Name+".bin");

thank you by the way
