Why Turbo C Rejects a Simple "Hello World" Program

Despite its ubiquitous use in tutorials and as an introductory exercise, a fundamental "Hello World" program fails to compile when attempted with Turbo C . This perplexity arises due to a disparity between Turbo C and modern C standards.

Turbo C adheres to a pre-ANSI C dialect, significantly divergent from the prevailing C renditions. This incompatibility prompts the compiler to flag multiple errors.

Resolving the Errors

To rectify the issues, modify the program as follows:

#include  // Note the ".h" suffix
int main()
{
    cout 
The Disparity Between Turbo C   and Modern C  
Although the adjustments appear minor, they highlight the substantial discrepancy between Turbo C   and its contemporaries. While comprehending pre-ANSI C   concepts may facilitate learning, the absence of up-to-date resources and the limited support within the community make it an undesirable option.
Why Avoid Turbo C  
Using Turbo C   poses several disadvantages:
It hinders compatibility with standard C   resources.
It restricts access to modern C   features.
It may instill incorrect or outdated habits.
Alternatives to Turbo C  
Embracing a modern C   compiler is highly recommended, such as:
Visual C   Community Edition (IDE and compiler from Microsoft)
Code::Blocks (lightweight IDE)
Eclipse CDT (cross-platform IDE with optional compiler installation)
Additionally, online compilers (e.g., IDEONE, OnlineGDB, Coliru) offer convenient platforms for code experimentation.
Conclusion
While nostalgically appealing, Turbo C  's outdated nature renders it a less-than-ideal choice for learning modern C  . By embracing modern C   compilers and resources, learners can bypass the aforementioned challenges and access a vasto array of up-to-date support.
