When printing strings (or text), the syntax is as follows: std::cout << “Hello World”; A pair of double quotes (") surround the text to be outputted, and the entire line of code finishes with a semicolon (;). We can't use the std::cout function right away since we don't have the header file we need to utilize these standard input/output methods. To do so, we'll need to use the built-in library! # Part 2 Now let try the basic escape in C++ Escape sequences are special characters characterized by a backslash (\) and a letter or symbol beside it. It is used in std::cout statements to show spaces, new lines, or show symbols that cannot be outputted using the normal way of printing. There are a lot of escape sequences available in C++, but we will only be tackling the most basic ones. try this code #include int main(void) { std::cout<<"G\n\nO\n\nG\n\nO"; return 0; } ![Capture1.PNG](https://files.peakd.com/file/peakd-hive/eleses/23t74pE3897T4KNjsTJrGzBzcowZYiApt4jnME83bxQLQ2fATTs8RVSM9WqWRQeWccPRi.PNG) # Part 3 Basic math Just like your elementary mathematics, C++ also has a similar set of math operations, with an addition of some other set of symbols for specified purposes. try this code #include #include int main(void) { int a = -8 ; int b = -2; int total = a + b; std::cout<<"-8+-2="< #include int main(void) { int a = 4 ; std::cout<<"C "; std::cout<< a; return 0; } ![3.PNG](https://files.peakd.com/file/peakd-hive/eleses/23t74pF2KbqtJiJ9H43AViH95xKunoetfcaubVUeCfW3mCtzRG3BhDgH5nL9K27Bm1DeY.PNG)
