Thread: array copy problem

I have a basic code where I can copy an array without problems. But when I introduce another kind of array, a more advanced variant which I think is called a dynamic array. Then my program crashes every time.
What am I doing wrong? What have I misunderstood?


Array tutorial: C Code Listing 7 - Array tutorial = [ Works ]

Code:

#include <stdio.h>

int main()
{
    short age[4];
    short same_age[4]; 
    int i, j;

    age[0]=23;
    age[1]=34;
    age[2]=65;
    age[3]=74;

    for(i=0; i<4; i++)
        same_age[i]=age[i];

    for(j=0; j<4; j++)
        printf("%d\n", same_age[j]);

    system("PAUSE");	
    return 0;
}

When I uncomment the /* Copy array */ code then the program doesn't work anymore.
Why is it happening at this location? What am I doing wrong? What have I misunderstood?
