}

Answer 1

Error in this line

myStud.add(new student__c(getEm.first_name__c+' ' + getEm.name));

this should be name value pair.

myStud.add(new student__c(Name = getEm.first_name__c+' ' + getEm.name));

You need to specify Field API name and respective value like this Name = getEm.first_name__c+' ' + getEm.name
