Addressing the LNK2019: unresolved external symbol error in C
In the realm of C programming, the dreaded LNK2019 error can often leave developers perplexed. This error arises when the linker fails to locate an external symbol named _main during the compilation process.
Within the provided code, the implementation of a sequence class raises this error. While the code appears to be modular and type-safe, the fundamental problem lies in the absence of a defined main function elsewhere in the project.
To remedy this error, consider the following steps:
<code class="cpp">int main() { // Program logic goes here return 0; }</code>
In Visual Studio, if you encounter this error even with a defined main function, the following workaround may prove helpful:
This modification instructs the linker to expect a console application executable.
Once these steps are implemented, the linker should successfully resolve the external symbol reference, allowing the program to compile and execute seamlessly.
