//RESULT 
// Size of int is 4bytes
// int max value is 2147483647
// int min value is-2147483648 (the 1 bit difference from the max value is coming because of the 0 as it's counted as well.)
// size of unsigned int4bytes
// Uint max value is 4294967295
// Size of bool is 1bytes
// Size of char is 1bytes
// size of float is 4bytes
// size of double is8bytes
