About this book
In this text we are shown examples for both those who are just starting out in this language for intermediate programmers, in order to deepen the knowledge in a practical and therefore easy and fast learning, in fact, doing practical examples you can understand and learn quickly what you are seeing. In this text are presented 40 examples of functions and instructions are not very large to facilitate learning and minimizing confusion in the code, especially for those just starting out, because especially for those who are beginners a long code can be slow down the learning curve.

C++
C ++ is one of the most powerful programming languages, in fact it is used in many of a certain importance software.
In this text we are shown examples for both those who are just starting out in this language for intermediate programmers, in order to deepen the knowledge in a practical and therefore easy and fast learning, in fact, doing practical examples you can understand and learn quickly what you are seeing.
In this text are presented 40 functions and other instructions with examples not very large to facilitate learning especially for those just starting out.

16) The function replace
17) The function find
18) The function insert
19) The function length
20) The function tolower
21) The function toupper
22) Define
Some mathematical functions
23) The function sqrt
24) The function pow
25) Generate random numbers
26) The abs function
27) The functions getchar e putchar
28) A program that only accepts numbers

40) Convert the data types
1)
Enter a string
#include <iostream>
using namespace std;
int main()
{
char n[8];
cout << "Inserisci max 8 caratteri" << endl ;
cin >> n;
cout << n ;
return 0;
}
Declare an array of 8 characters, then we ask the user to enter characters using the cin function and eventually we print on screen the characters you have entered the function cout, endl is used for the carriage return.
2)
The function setprecision
With setprecision () function we can take a certain number of digits to be printed on the screen.
To ensure that you do not get an error you have to insert the header file <iomanip> as it appears in the following example.
#include <iostream>
#include <string>
#include <iomanip>
