c - Is typecasting on lvalue of operation not allowed? -

i have below code, doing type cast of integer pointer void pointer , try assign char address.

void main() {    int *ptr;    char = 10;    (void *)ptr = &a;    printf("%d\n", *ptr); } 

i getting below error, there anyway can fix this?

error: lvalue required left operand of assignment     (void *)ptr = &a; 

yes, you cannot cast left operand of assignment operator in c.

also, in case other way make code work:

void main() {    int *ptr;    char = 10;    ptr = (int*) &a; // fine    printf("%d\n", *ptr); }
