    Segmentation fault?

    I can' t stand any more...i need help...
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    
    struct Employee{
           int i;
           int age;
           char name[30];
    };
    
    void init(struct Employee *buf, int count){
         int i;
             for(i=0; i<count; i++){
                      printf("Please type a age between 20 and 65:\n");
                      scanf("%d", &(buf->age));
             }
    } 
    int main(int argc, char *argv[]){
           int i, n;
           struct Employee *buf;
           
           n = atoi(argv[2]); // n einai to megethos tou pinaka
           buf = (struct Employee *)malloc(n*sizeof(struct Employee));
           /*  Edw tha kalesoume tin synartisii */
           init(buf, n);

    Code:
    scanf("%d", &(buf->age));
    This should be more something like:
    Code:
    scanf( "%d", &( buf[ i ].age ) );
    You should also check your return values from malloc and your other functions to see that they're doing what you expect of them.

    Hope is the first step on the road to disappointment.
