C/C++ Structure

C++ Syntax

int, string, char, bool keywords are used to declare variables.
Variables are like your x and y in algebra where x and y can take any value.

Conditional operators like
       if(){
       ...
       } else {
       ...
       }
give different options for different conditions.
For instance:

if(age > 18){
std.cout << "You are grown-up now.\n";
} else {
std.cout << "You are still young.";
}


while loop:
       while(){
       ...
       }

and

for loop:
       for(){
       ...
       }
.

The arithmetic operators do exactly what you would expect:
       + means add;
       - means subtract;
       * means multiply;
       / means divide; and
       % means moduli.

// are used for single line comments.
/* ... */ are used for multi-line comments.
Comments are just remarks (explanations) you write along side your code for clarity purposes (help you define what you are doing); and also for future remembrance of what a piece of code was meant for.

The compiler neither needs nor processes them.
