Output the line in uppercase letters and in lowercase letters. 8.7 (Converting Strings to Integers for Calculations) Write a program that inputs six strings that represent integers, converts the strings to integers, and calculates the sum and average of the six values. 8.8 (Converting Strings to Floating Point for Calculations) Write a program that inputs six strings that represent floating- point values, converts the strings to double values, stores the values into a double array and calculates the sum, and average of the values 8.9 (Comparing Strings) Write a program that uses function strcmp to compare two strings input by the user. The program should state whether the first string is less than, equal to or greater than the second string 8.10 (Comparing Portions of Strings) Write a program that uses function strncmp to compare two strings input by the user.
