Which of these is the correct way to set the value of a string variable?
(a) destination_string =
"This is the string contents that I want.";
(b) strcpy(destination_string,
"This is the string contents that I want.");
2. Suppose that a character string named my name has been declared and allocated at length 100. Write a statement that would set its contents to your name.
3. Suppose that a character string named my name has been declared and allocated at length 100. Write a printf statement that outputs to stdout the string variable’s contents, followed by a newline.
