What is Computer Science? Can someone please explain to me?

Can someone please explain the answers to these computer science questions?

• Consider the following variable declarations in C are placed starting at memory byte address 800. Assume 4 bytes to a word and each word is 32 bits. Assume variable array is a string ...show more

• Answer:

  the word stores an int 3 so that's in hex: 00 00 00 03 therefore the first byte is 0x00 for part b you start at 800 + 4(int) + 4(float) + 4(pointer) = string starts at 812 Now you have to understand that an array is really just a group of the same type of thing in memory ... a char is a one byte data type so big or little endianess doesn't apply. The memory in big or little endian for that char array will both look like a b c d e f if it was an array of ints then each individual element would have reversed bytes but you do not reverse the elements themselves. (I hope that makes sense) the element order stays the same.
