What is the output produced by the following code? string s1, s2("Hello"); s1 = s2; s2[0] = 'J'; cout << s1 << " " << s2;
What C string will be stored in singing_string after the following code is run? char singing_string[20] = "DoBeDo"; strcat(singing_string, " to you"); Assume that the code is embedded in a complete and correct program and that an include directive for \(< c\) string \(>\) is in the program file.
Consider the following code (and assume it is embedded in a complete and
correct program and then run):
char my_string[80];
cout << "Enter a line of input:\n";
