You can't use strcmp for strings.
if(strcmp(data[i]->getname(),namesearch)==0)
Use
1
2

if (data[i]->getname() == namesearch)
{
// display found message
}

thank you so much
my problem is sloved
so we just using strcmp for char?
Actually you use strcmp() to compare two C-strings, not single characters.
