Solution

The first error that the compiler returns is on line 11 of the main.c file. The error message states that the variable 'i' is undeclared, which means it has not been defined before being used in the for loop. Additionally, on line 9, there is a warning that the variable 'hello' is set but not used in the code. These warnings are treated as errors because of the compiler flags -Werror and -pedantic.
