Guys,
Create powerful apps for the world’s most popular smart phone platform with Symbian C++
Symbian provides a secure, reliable operating system for smart phones and is created in Symbian C++
Symbian C++ has been designed to run efficiently on devices with relatively limited memory and power resources. Several elements of Symbian C++ therefore differ from desktop C/C++ because of these requirements. Specific examples include a leaving mechanism that protects apps against a lack of requested resources and special handling of data through descriptors. While these mechanisms may be unfamiliar at first, once mastered they enable the coding of robust and efficient apps.
