Question
home/ubuntu/Main.cpp: In function ‘int main()’:/home/ubuntu/Main.cpp:60:13: error: ‘exit’ was not declared in this scope 60 | exit(0); | ^~~~
Solution
The error message you're seeing is because the exit function is not recognized in your code. This function is part of the cstdlib library in C++.
To fix this error, you need to include the cstdlib library at the beginning of your code. Here's how you can do it:
-
At the top of your
Main.cppfile, add this line:#include <cstdlib> -
Save your changes and recompile your code.
This should resolve the error and allow your program to recognize the exit function.
