Question

hi, I want to write a program in C++ that locates strings after acertain command, program takes the input from the command line andlist all the inputs in a linked list using structs.the command is aletter "E" and the following data need to be located after theletter , the data is just a name and an ID number. example : E MIKE 999999       // stored in the linked list . the command line can contain as much as data as thereis, example : E MIKE 999999 E JACK 333333 E DEAN 777777 . . . . . .. the first string after "E" must be a name , and the secondletter is the ID . . . pleas i want the codes with comments . . . hi, I want to write a program in C++ that locates strings after acertain command, program takes the input from the command line andlist all the inputs in a linked list using structs.the command is aletter "E" and the following data need to be located after theletter , the data is just a name and an ID number. example : E MIKE 999999       // stored in the linked list . the command line can contain as much as data as thereis, example : E MIKE 999999 E JACK 333333 E DEAN 777777 . . . . . .. the first string after "E" must be a name , and the secondletter is the ID . . . pleas i want the codes with comments . . .

Explanation / Answer

struct student
{
       char name[100];
       int id;
       struct student *next;
}*first,*last;

int      insert_node_in_order(struct student *temp)
{

         
          if(first ==NULL)
          {
          last=first=temp;
          }
          else
          {
         last->next = temp;
          last =temp;   
          }
         

}
int main(int argc,char *argv[])
{
    char ch[5];int len;
    char name[100];
    struct student *temp;
    first =NULL;
    int count=1;

      while(count<argc)
      {
     
      temp = new struct student;
     
      strcpy(temp->name,"");
      again:
           
     strcat(temp->name,argv[count]);   
      strcat(temp->name,"");   
      count++;
      if((argv[count][0] >='a'&& argv[count][0]<'z')||(argv[count][0] >='A'&& argv[count][0]<'Z'))
      {
      goto again;
      }
      else
      temp->id =atoi(argv[count]);               
     
      temp->next = NULL;
      insert_node_in_order(temp);
      count++;
      }
     
temp = first;

while(temp!=NULL)
{
cout<<"Name = "<<temp->name<<endl;
cout<<"Id   ="<<temp->id<<endl<<endl;
temp = temp->next;
}
cout<<endl;
system("pause");
}
