This problem has different answers on different compilers.
I had used turboc3, where is always printf "not equal".
Because the size of float is 2 bytes and size of double is
4 bytes, So, when compiler checks this, it can only compare
two bytes rest are left un checked and thus it concludes
false condition. It is same on RHEL5 environment.
Where as on Visual Studio 6.0, It will yield "Equal",
because here both the float and double variable acquires
the same space in memory. Thus the compiler can compare all
four bytes of memory which in fact contains the same values
because the representation of value is same in float and in
double.

What is realloc in c?
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.
