In C programming, void main() is an incorrect signature for the main function. The correct signature is int main(). The main function serves as the entry point for C programs and typically returns an integer to the operating system upon completion. Using void main() may lead to compilation errors.

In C programming, void main() is not a recommended or standard way to declare the main function. The correct signature for the main function is either int main(void) or int main(int argc, char *argv[]). Using void main() is considered bad practice and might result in undefined behavior or compilation errors. The main function should return an integer, typically zero to indicate successful execution, and the int type should be specified in the function declaration. Here's an example of a standard main function signature: int main(void) { // Your code here return 0; } read less

void main() suggests no return value, which is not standard. Use int main() and return an integer at the end of the program (typically return 0; for successful execution)
