)using newline command : endl
#include
using namespace std; int main()
{
cout < < "my first c++ program." < < endl;
cout < < "the sum of 2 and 3 = " < < 5 < < endl;
cout < < "7 + 8 = " < < 7 + 8 < < endl;
return 0;
}

The output of the code is following:-

My first C++ program.

The sum of 2 and 3 = 5

7 + 8 = 15

Explanation:

First the program should have #include<iostream>.This is missing in the program.

In the program you have printed My first C++ program first then used newline character endl. After that you have printed The sum of 2 and 3 = 5 this will be printed in the new line.Then you have used endl.Then printed  "7 + 8 = " string and the sum 7+8 that is 15.

Hence the output is like this.
