Implement function bin2dec that takes a binary number bin_num as a string argument and prints out the corresponding decimal numb
er. Each char in the string has a value of either '0' or '1' to represent a bit. The string does not have any leading space. For example, function call bin2dec("1011") should print 11. You can assume that bin_num can have up to 32 bits. To convert a char in the binary number string to an int, you can subtract the char by '0'. For example, you can use bin_num[0] - '0' to get the int value of the most significant bit of the binary number. Restriction: printf is the ONLY C library function that you can use in the implementation.
An excel user should use a relative cell reference when it is important to preserve the relationship to the formula location. When you create a formula that references other cells, excel does not normally "record" the exact cell address. Instead, it looks at the at the relationship that cell has to the other cell containing the formula.
The power supply is what essentially enables the computer to operate. It is able to do that by converting the incoming alternating current (AC) to direct current (DC) at the correct wattage rating that is required by the computer to function. The power supply is a metal box that is generally placed in the corner of the case.
