Hexadecimal to Binary in CWhat is hexadecimal?The hexadecimal is a positional system that represents the numbers in sixteen distinct symbols by using 16 as a base. These distinct symbols, i.e., "09" represents the values from zero to nine, and "AF" represents the values from ten to fifteen. What is Binary?The binary is a number which is represented with a base 2 numeral system, and it uses two symbols, i.e., 0 and 1. Examples Suppose the hexadecimal number is A12C. Now we calculate the binary value of the hexadecimal number. Hexadecimal number=A12C Binary value equivalent to A is 1010 Binary value equivalent to 1 is 0001 Binary value equivalent to 2 is 0010 Binary value equivalent to C is 1100 Therefore, the binary value equivalent to A12C is 1010000100101100. Note: To convert hexadecimal into a binary number, the binary value of each digit of a hexadecimal number is evaluated and combined to get the binary number of a given hexadecimal number.Let's understand through an example. In the above code, we want to calculate the binary value of "A12C". We first store this value in a character array named as hex[], and then we pass this array to a hextobin() function. The hextobin() will calculate the binary value of the number, it iterates over each element of an array through a while loop, and finds the binary value of each corresponding element through a switch statement. Output 1010000100101100
