WebbOne can find the memory consumed by a data type as follows: int main() { printf("size of int : %d\n",sizeof(int)); printf("size of signed int : %d\n",sizeof(signed int)); printf("size of unsigned long : %d\n",sizeof(unsigned long)); return 0; } Ideally, memory consumed by the signed and unsigned variants are the same.
