6. (5 Points) Write functions in C to convert from decimal to hex and from decimal to binary using the function prototypes provided below Your code must have a main function to test the two functions. Your functions only need to work with decimals less than or equal to 255 and greater than or equal to 0. Please don't leave or use printf statements in the functions. This function takes a decimal number and converts it into hexadecimal string. void convert_decimal_to_binary(int decimal, char binaryI) This function takes a decimal number and converts it into binary string. Some test code in main: char hex [3] convert_decimal_to_hex (255, hex) printf("255 to hex is %s ", hex); char byte [91 convert_decimal_to_binary (25, byte) printf("25 to bin is %s ", byte); 255 to hex is FF 25 to bin is 00011001
