Answer:
a. Write C++ statements that include the header files iostream and string.
#include <iostream>
#include <string>
b. Write a C++ statement that allows you to use cin, cout, and endl without the prefix std::.
To use cin and cout, one must first declare at least one variable. At this point, I'll assume that the variable has been declared already I'll name my variable "test" without the quotes.
cin>>test;
cout<<test<<endl;
c. Write C++ statements that declare the following variables: name of type string and studyHours of type double.
string name;
double studyHours;
d. Write C++ statements that prompt and input a string into name and a double value into studyHours.
string name;
double studyHours;
cout>>"What's your name?";
cin<<name;
cout<<"What's your study hours?";
cin>> studyHours;
PS: A full program in C++ that illustrates the above
#include <iostream>
#include <string>
using namespace std
int main()
{
string name;
double studyHours;
cout>>"What's your name?";
cin<<name;
cout<<"What's your study hours?";
cin>> studyHours;
cout<<"Hello "<<name<<", your study hour is "<<studyHours;
return 0;
}
