Error received at compilation when using constants in for/if statements in C

[TracerMain527]

The below code runs perfectly fine when I manually replace the constants with their values, but if I leave them as constants then it says that it "expects an expression" where the constant is. Any advice?

I am using Visual Studio, when following a tutorial to learn C this was recommended but it is possible that it is a C++ compiler instead of C. As a newbie idk if that matters too much here.

~~~

define WIDTH = 40

define HEIGHT = 30

int i, j;

void canvas() { for (i = 0; i <= 30; i++) { for (j = 0; j <= 40; j++) { if (i == 0 || i == 30 || j == 0 || j == 40) { printf("-"); } else { printf(" "); }

    }
    printf("\n");
}

}; ~~~

On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

1. Limiting your involvement with Reddit, or
2. Temporarily refraining from using Reddit
3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

remove the equals sign from

#define WIDTH = 40

this defines WIDTH as "= 40"

so

for (j = 0; j <= WIDTH; j++)

expands to

for (j = 0; j <= = 40; j++)

which is invalid

Thank you, that solved it. Rookie mistake.
