#include <iostream>
using namespace std;
int main() {
// Declare variables
char character = 'a';
int integer = 123;
float floating_point = 1.23;
string message = "Hello, world!";
// Print the text in 4 lines
cout << "This is a character: " << character << endl;
cout << "This is an integer: " << integer << endl;

}
This program first declares 4 variables: a character variable character
, an integer variable integer
, a floating-point variable floating_point
, and a string variable message
. Then, it prints the text in 4 lines, using the cout
statement. The endl
manipulator is used to insert a new line at the end of each line.
To run this program, you can save it as a .cpp
file and compile it using a C++ compiler. For example, on Linux or macOS, you can use the following command to compile the program:
g++ -o program program.cpp
Once the program is compiled, you can run it by typing the following command:
./program
This will print the following output:
This is a character: a
This is an integer: 123
This is a floating-point number: 1.23
This is a string: Hello, world!
