Hexadecimal Number numbers by looking at only four digits at a time. For example, binary 1111 equals hexadecimal F, binary 0100 equals hexadecimal 4, and binary 11110100 equals hexadecimal F4: 1�1110�100 F 4 When converting a binary number to hexadecimal by this method, start by adding zeros at the left in order to make the [...]

Binary Number 21 × 13 63 21 273 First, find 3 × 21. Then, find 10 × 21, and add these two results together to get the final product. Note that the product has more digits than either of the two original numbers. You can follow the same procedure to multiply two binary numbers: 10101 × 01101 10101 00000 10101 10101 [...]

The same applies to the search algorithms. For finding out a particular number in an array, we can use technique of linear search. In this technique, there may be as many comparisons as numbers in the array. We make comparison of the number to be found with each number in the array and find it [...]

In C language we have the usual arithmetic operators for addition, subtraction, multiplication and division. C also provides a special arithmetic operator which is called modulus. All these operators are binary operators which means they operate on two operands. So we need two values for addition, subtraction, multiplication, division and modulus.   ARITHMETIC OPERATION ARITHMETIC [...]
