I try to change the value of a variable (first_var) from an already known Address. i.e I already know what its address is, though I dont have a pointer to it..
I wrote the code below in an attempt to change its value from the address thats already known, which is 0x61fdfc, without getting its pointer by writing something like:
&first_var
This is the code:
#include <iostream>
int main(){
int first_var = 10;
long *addr = 0x61fdfc;
std::string s;
*addr = 20;
std::cin >> s;
return 0;
}
Though when I compile it(By GCC compiler), I get that error:
.cpp: In function 'int main()': editor.cpp:5:15: error: invalid conversion from 'int' to 'long int*' [-fpermissive] long *addr = 0x61fdfc;
How do I fix that error, and how do I get it working as expected?
