The string of characters \"Good Morning\" is to be stored in a character array named goodstrl. Write the declaration for this array in three different ways.

a. Write a declaration to store the string \"This is a test\" into an array named strtest. Include the declaration in a program to display the message using the following loop:

b. Modify the for statement in Exercise to display only the array characters t, e, s, and t.

c. Include the array declaration written in Exercise in a program that uses the printf ( ) function to display characters in the array. For example, the statement printf ( \"%s\", strtest); will cause the string stored in the strtest array to be displayed. Using this statement requires that the last character in the array is the end-of string marker \\ o.

d. Using a while loop. (Hint: Stop the loop when the \\0 escape sequence is detected. The expression while (strtest [i] != '\\0') can be used.)
