The preceding LML program reads two numbers from the keyboard and determines and prints the larger value. Note the use of the instruction +4107 as a conditional trans- fer of control, much the same as C's if statement. In-Class Tasks Write LML programs that accomplish each of the following tasks: Use a sentinel-controlled loop to read 10 positive integers and compute and print their sum 1. 2. Use a counter-controlled loop to read seven numbers, some positive and...

(While-loop controlled by a sentinel value) Write a program that reads an unspecified number of integers. Your program ends with the input 0. Determine and display how many positive and negative values have been read, the maximum and minimum values, and the total and average of the input values (not counting the final 0).
