Read MoreGiven an int variable named yes Count and another int variable named no Count and a char variable named response, write the necessary code to read a value from the text box text Box into response and then carry out the following: if the character typed in is a y or a Y then increment yes Count and print out “YES WAS RECORDED”. if the character typed in is an n or an N then increment no Count and print out “NO WAS RECORDED”. If the input is invalid just print the message “INVALID” and do nothing else.

Read MoreWrite a Select Case statement that tests the value of the integer variable semester Average and assigns a grade to the string variable grade based upon the usual criteria (i.e., greater than or equal to 90 is an A, between 80 and 89 inclusively is a B, etc). If the average falls outside the range of 0 and 100, grade should be assigned the empty string and the message “Invalid semester average” should be displayed in a message box.

Read MoreGiven int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus your code should put 1*1 + 2*2 + 3*3 + … + 49*49 + 50*50 into total. Use no variables other than k and total.

Read MoreGiven an int variable n that has been initialized to a positive value and,in addition, int variables k and total that have already been declared,use a while loop to compute the sum of the cubes of the first n counting numbers, and store this value in total. Thus if n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into total. Use no variables other than n, k , and total. Do NOT modify n.
