Pointer to a consttant ::: such that the value to which
pointer points can't be changed
const int *ptr1=7
*ptr=8 // invalid
constant pointer :::: pointer direction can't be cheged .
int *const x =6;
x=7 or x=&i // invalid
Location of pointer can't be chenged.

why do some people write if(0 == x) instead of if(x == 0)?

The program will first compute the tax you owe based on your income. User is prompted to enter income. Program will compute the total amount of tax owed based on the following: Income Tax 0 - $45,000 = 0.15 x income $45,001 - $90,000 = 6750 + 0.20 x (income – 45000) $90,001 - $140,000 = 15750 + 0.26 x (income – 90000) $140,001 - $200,000 = 28750 + 0.29 x (income – 140000) Greater than $200,000 = 46150 + 0.33 x (income – 200000) Dollar amounts should be in dollars and cents (float point numbers with two decimals shown). Tax is displayed on the screen.
