expected a type specifier in C

Question

All of my programs before have been working well with C except for today. For some reason I keep getting "expected a type specifier"

I am confused why this is not working.

#include <stdio.h>
printf("Hello World"); // error: expected a type specifer

int test = 90;
printf("%d", test); // same error here: expected a type specifier 
// also getting "variable "test" is not a type name"

You cannot have statements outside of a function in C. That's what is causing the errors you're seeing.

The main function serves at the starting point for a C program, so start by putting the statements in that function.

#include <stdio.h>

int main()
{
    printf("Hello World");

    int test = 90;
    printf("%d", test);

    return 0;
}
