Error when compile program

[Lukas]

Hello guys Can someone help me with the program,. Code in C i have right down but when i try to compile, every time there is an error: ‘temp1’ is used uninitialized in this function int gamefield[temp1*2];
compile start by gcc -std=c11 -Werror -Wall -lm

Thanks for some help im like beginner in programming

#include <stdio.h>
#include <stdlib.h>

#define VAR 0.00000000001

int main(){
    int temp1,temp2;
    int spins = 0;
    int a = 0;
    int b = 0;
    double infinity = 10000000;
    double summary = 0x00;
    double count = 0x00;
    int gamefield[temp1*2];
    int surface[temp1];
    int temp3[temp1];

    scanf("%d %d",&temp1,&temp2);
    
    while(spins != temp1*2)
    {
        scanf("%d",&gamefield[spins]);
        spins++;
    }

@Lukas, when the compiler says something is "uninitialised", it means that you haven't initialised your variables with a value. In this case, you need to go back and give both temp1 and temp2 values.

Alternatively, you can remove the -Werror -Wall arguments, and that permits the program to be compiled. You can see what these arguments do here: https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#Warning-Options

If none of this is what you're looking for, please let me know.

I cant remove the -Werror and -Wall arguments because of BOT testing program... and second problem is i dont know what value give temp1 and temp2..
