— Missed a returned value
Hey guys I already know C language and now I want to extend my knowledge to C++ so which book is best to start learning C++ best in the sense which gives reference and comparision with C and not covering same topic in depth again like pointers, arrays etc..
— Psst
— Lol why you don't use monospace font
— Void fun(int arr[])
{
int i;
int arr_size = sizeof(arr)/sizeof(arr[0]);
printf("%d\n",sizeof(arr));
printf("%d\n",sizeof(arr[0]));
for (i = 0; i < arr_size; i++)
printf("%d ", arr[i]);
}
int main()
{
int i;
int arr[4] = {10, 20 ,30, 40};
fun(arr);
return 0;
}
— OUTPUT produces 8 4 and 10 20
— Can someone explain me how 8 is the size of the array
— Wtf
— Don't use sizeof/sizeof
— It doesn't work
— Use a variable to pass the size
— Why are you trying to calculate the size of array when you already know? pass an extra argument in the function for array size
