More About C++ Statements

A C++ program is a collection of functions, and each function is a collection of statements. C++ has several kinds of statements, so let's look at some of the possibilities. Listing 2.2 provides two new kinds of statements. First, a declaration statement creates a variable. Second, an assignment statement provides a value for that variable. Also, the program shows a new capability for cout.

Listing 2.2 fleas.cpp.
// fleas.cpp -- display the value of a variable
#include <iostream>
using namespace std;
int main()
{
    int fleas;             // create an integer variable
    
    fleas = 38;            // give a value to the variable
    cout << "My cat has ";
    cout << fleas;         // display the value of fleas

    return 0;
