HomeWork Write a program in C to simulate backward and forward functionality just like a wetb browser. Your program should have at least two functions, backward) and forwardO For example, the user enters two string such as "Testl" and "Test2". 1) Case one: If the user selects backward, "Test2" will be printed. Then if the user selects backward again, "Tes" will be printed. Then if the user selects backward a third time, a message such as "empty" will be printed 2) Case two: If the user selects backward, "Test2" will be printed. Then if the user selects forward, "Test2" will be printed. 3) Case three: If the user selects backward, "Test2" will be printed. Then if the user selects backward again, "Testl" will be printed. Then if the user selects forward, "Test" will be printed
