Struct/array help

Original - C++ Code int main() { StudentRecord TESCStudent; char* blah; blah = (char*) malloc(20); cin >> blah; strcpy(TESCStudent.Name,blah); cout << blah << "\n" << TESCStudent.Name << "\n"; TESCStudent.ID=1234; TESCStudent.GPA=4.0; cin >> blah; return 0; }

int main()
{
    
StudentRecord TESCStudent;
char* blah;
blah = (char*) malloc(20);
cin >> blah;
strcpy(TESCStudent.Name,blah);
cout << blah << "\n" << TESCStudent.Name << "\n";
TESCStudent.ID=1234;
TESCStudent.GPA=4.0;
cin >> blah;
 
return 0;
} 

 TESCStudent.Name[]="SuperProgrammer";

memset(TESCStudent.Name, 0, 20); //clear out the string. it now appears to the computer that the Name string ends at the first character (i.e. an empty string)
strncpy(TESCStudent.Name, "SuperProgrammer", 19); //copy SuperProgrammer into the string. the 19 makes sure that only 19 characters are copied (not 20 because we need at least one null char at the end so that the computer knows where the string ends) (this is unnecessary here, but entirely necessary when you don't know what string you are copying in, because if you write past the end of Name then (in this case) ID and GPA will be corrupted, and etc until your program crashes)

#include <cstdlib>
#include <iostream>

using namespace std;

struct StudentRecord

       char Name[20];
       int ID;

/*Creates an object of StudentRecord named TESC_Student with
the values in the {}. This is a very easy way to put values to
your structs especialy if there not going to be user defined.
just go in order seperated by comma's =)*/
