#include <studio.h>
int main(void) {
printf("Watch, Where, You, Walking!\n");
return 0;
}
This is the code I wrote, and here is the error message that I got:
C:\Users\exoar\OneDrive\Computer\collect2.exe [Error] ld returned 1 exit status
You have a spelling error in the first line:
#include <stdio.h> // this is the correct include-statement
Edit: This is probably not the solution to the problem. Nonetheless this is a further problem of the code.

I'm using codeblocks IDE and I don't know what is the problem.
I tried making the variables global but it still doesn't work.
The problem is in the function name. Calculate_area has a capital 'C' in its function declaration name, but not in the prototype declaration.
Change your function declaration at line 31 with:
unsigned long calculate_area(unsigned long side);

There's shouldn't be a semicolon in the int main(void); declaration.
Try replacing line 4 with: int main(void) instead.
Also, please read up on C function declaration syntax
https://msdn.microsoft.com/en-us/library/c4d5ssht.aspx.
int main(void);
^you should not do this.
And you forgot to put ; after this statement -
int height=n
And also n is not declared in your program.

I am making a C program that is a simple calculator without a GUI, called "Quical". (Check out the code on Github). I am somewhat new to C, and so I am making some syntax errors. One of the errors is this:
expected declaration or statement at end of input
Another one of the errors that comes up is this:
else without a previous if
Here is my code.
Hopefully, this can shed some light as to why I am getting these syntax errors. Any help would be much appreciated.
Your braces don't match. You have something like
main()
{
some statement
{
}
another
{
}
and it ends.
It is saying it wants a statement here. Try that and see what the next error is.

# define a 10
main()
{
#define a 50
printf("%d",a);
}
The output is coming 50. Why is it happening so? Shouldn't the output come 10?
Compilation happens from top to bottom. so value of a is replaced by 50 when it enters into main function.
Here the local has precedence than global
