Question

when i try to assign values to dynamic array using function scanf, i’ll get this error “Signal received: SIGSEGV (Segmentation fault)” after first assign, but when I use cin, it works and all values are assigned correctly. Why? Is the problem in my code?

int main(int argc, char** argv) {
int r = 5;

short* pole[r];


for(int x = 0;x<r;x++){
    pole[x] = new short[r];
    for(int y = 0;y<r;y++){
        scanf("%d",pole[x][y]); //error
        //cin >> pole[x][y]; //OK
    }
}

}

You’re missing an ampersand, and the %d should be %hd (for short int):

scanf("%hd",&pole[x][y]);

Your original version was passing the value of pole[x][y], whereas scanf() expects a pointer. Also, the type specifier (%d) was wrong for the type of &pole[x][y].
