Problems to compile NewPing code for multi sensors ranging application

Other Hardware Robotics

To any expert in C programming;

Has anyone experienced these errors feedback while attempting to compile the code?
If yes, what are the corrections? The code is a copy from 15 sensors code from Teckel I believe and added my own code for external processes.
See list of errors below.
Newping_Code_for_Multiple_Sensors:16: error: 'NewPing' does not name a type
Newping_Code_for_Multiple_Sensors:17: error: 'NewPing' does not name a type
Newping_Code_for_Multiple_Sensors.ino: In function 'void loop()':

Newping_Code_for_Multiple_Sensors:35: error: 'sonar' was not declared in this scope
Newping_Code_for_Multiple_Sensors:38: error: 'echoCheck' was not declared in this scope

Newping_Code_for_Multiple_Sensors:47: error: a function-definition is not allowed here before '{' token

Thank you ,

The "does not name a type" message almost always means you didn't install the matching library correctly. Try again.
