vector/list of structs

[ppp]

Hello,

I'm trying to create vector of structs and I'm having problems updating it. Let me give you an example:

     #include <iostream>
     #include <list>
     #include <string>
     #include <vector>
     using namespace std;
     
     struct process{
     
     string pid;
     string type;
     int duration;
     int timer;
      
     void some_fun (int p){ p++;}
     
     }pr;
          
     int main(){
      
     vector <process> v;
     //how to push_back some values to struct variables on the top?   
     }//end of main

Thanks in advance.

Hi,
I hope you can help..

typedef int DATATYPE;

struct VECTOR {
DATATYPE *pArray;
size_t count;
size_t capacity;
} 


VECTOR *CreateVector(size_t capacity)
{
	VECTOR *hVector;

	if ((hVector = (HVECTOR) malloc(sizeof(VECTOR))) == NULL)
		return NULL;

	hVector->capacity = capacity ? capacity : DEFAULT_CAPACITY;
	if ((hVector->pArray = (DATATYPE *) malloc(sizeof(DATATYPE) * hVector->capacity)) == NULL)
	{
		free(hVector);
		return NULL;
	}
	hVector->count = 0;

	return hVector;
}

Thank you firix,


I found some way of doing it.

    
    int main(){
    vector <process> v;
    string p= "example";
    v.push_back(proc);
    v[0].pid = p; 
    
    cout<< "results: " << v[0].pid << endl; 

Thank you very much.

ok..

v.push_back(pr);
instead of
v.push_back(proc);

good luck....
