C - Issue with random number generator

I have an issue while generating a random number and giving the value to a pointer.

What I want to do here: generate a number between 1 and 1000, and the player will receive that amount of gold.
The base gold is 0 obviously.
Although, for some reason, when I printf the amount of integer gold, there were cases when it was more than 3000, which is obviously a sign of error.

The goldchange part is because the player will receive gold lots of times and I want it to work every time. Although at the moment, since I am testing this part of my program, the player receives gold only once.

Since I am a beginner programmer, I guess I am doing it wrong.
How should I do this correctly so integer GOLD will have the correct value?

int* gold=0;
int* goldchange;
printf("You have received the following amount of gold: %d", goldchange);

printf("You have this many golds: %d", gold);

So, for example, this was what happened last time:
You have received the following amount of gold: 777
You have this many golds: 3108

But it should be 777 not 3108....
(obviously every run gives different numbers, but the two values are never the same...)


You are declaring to variables as pointers with:

int* gold=0;
int* goldchange;

And then proceeding to treat these as regular int variables. In the given code I see no reason for declaring these variables as pointers. Why not just

int gold=0;
int goldchange;
