Question

EDIT:

Typedef struct SPro{
     int arrivalTime;
     char processName[15];
     int burst;
} PRO;

I have an array of type PRO

PRO Array[100];
PRO enteringProcess;
//initialize entering process

then I need to creat a new process and allocate memory for that process using malloc Then point the pointer from the array to the memory chunk that malloc returns.

PRO *newPro = (PRO *) malloc (sizeof(PRO));
newPro = enteringProcess;
ProArray[0] = *newPro;

It seems that I’m doing something wrong since my program crashes at run-time.
Any help? thanks!

Seems you need an array of pointers to PRO:

PRO *Array[100];

PRO *newPro = (PRO *) malloc (sizeof(PRO));
/* ... */
Array[0] = newPro;

I don’t know what that enteringProcess is, so I cannot give opinion. Just that you should not assign anything to newPro other than the return of malloc or else you will leak the new object.
