I'm trying to do a kwh calculation, facul work. I'm using float values and the kwh * 0.2 value must be calculated, but the result is always zero. And I'm not seeing any errors in the code.
Calculation in program C results in zero in any calculation value

Do not forget to initialize the variable
When you print the variable not the need to put the memory address of it
#include <stdio.h>
int main()
{
float calc = 0, kwh;
printf("Escreva seu consumo em kwh: ");
scanf("%f", &kwh);
calc = kwh * 0.2;
printf("Seu consumo e: %.2f \n", calc);
return 0;
}

printf("seu consumo e:%.2f \n", &calc);
// omite & para valor ^ assim é endereço de memória
The correct way is
printf("seu consumo e:%.2f \n", calc);
