Problem 1 At a local university, each engineering major requires a different number of credits for graduation. For example, recently the requirements were as follows: Civil Engineering 130 Chemical Engineering 130 Computer Engineering 122 Electrical Engineering 126.5 Mechanical Engineering 129 Prompt the user to select an engineering program from a menu. Use a switch/case structure to send the minimum number of credits required for graduation back to the command window. Problem 2.a Use a for loop to sum the elements in the following vector: [1, 23, 43, 72, 87, 56, 98, 33] x = Check your answer with the sum function. Problem 2.b Use a for loop to create a vector of the squares of the numbers 1 through 5.
