## printf formating

'%d' - integer placeholder
%f - floating point stuff aka decimal
%c - char
%s - string
%x - hex format, prints any INTs to hex format
%p - prints the pointer/address from input &var

## pointers

int a = 5;
int *p;
p = &a // assigning mem adr to a var
printf("pointer is at: %p\n",p);	//prints a mem addr*
printf("value at p: %d\n",*p);	//prints int 5

&  //address of something


#Useful function
-------------------

int x;
sizeof(x)  // gives how big int is in bytes.
getchar(); //waits for input, useful for examining


#terminal/commands
------------------

*check mem map*
cat /proc/[PID]/maps

*aslr check*
cat /proc/sys/kernel/randomize_va_space

*turn off aslr*
sudo bash -c "echo 0 > /proc/sys/kernel/randomize_va_space"

*dissassmble binary via object dump*
objdump -d binaryFileName
objdump -d binaryFilename | grep main // to narrow things down
