Write a program to determine the mass of oxygen gas (formula: o2, molecular weight = 32 grams per mole) in units of grams in a container. you may assume that the user will provide the volume of the container in units of gallons, the temperature in the container in degrees celsius, and the pressure in the container in units of atmospheres. for your test case, you may assume that the user provides 1.25 gallons for the volume of the container, 125 degrees celsius for the temperature, and 2.5 atmospheres for the pressure in the container

3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.
