Create a new program called Lab3-1.cpp. As a simple first step, declare an array of characters that can hold up to a maximum of 50 characters. Then ask the user to input a string, and store it in your character array. Use the standard stream I/O objects cin and cout to input t...
using namespace std; getline(cin, my_string, '\n'); String concatenation Strings can also be assigned to each other or appended together using the + operator: string my_string1 = "a string"; string my_string2 = " is this"; string my_string3 = my_string1 + my_string2; // Will...

Because C-style strings are fixed-size arrays, the solution is to declare an array larger than we are ever likely to need: #include<iostream>intmain(){charrolls[255]{};// declare array large enough to hold 254 characters + null terminatorstd::cout<<"Enter your rolls: ";std::cin>>rol...
