CAN YOU MODIFY THIS CODE SO IT DOES ALL THE CONVERSION INCLUDING DECIMAL TO HEX AND DECIMAL TO OCTAL. MAKE METHODS FOR BOTH CONVERSIONS PLEASE AND SHOW OUTPUT. #include #include #include #include #include /*Removed this method as it is not required char getche();*/ char* getDateAndTime(); /*changed the parameter from long to int*/ long DecimaltoBinary(int n); /*Added this method as it required*/ int getInteger(char* str_array); int main() { /*change the type of long to int as getInteger return the integer*/ int Decimal; do { char buffer[100]; printf(" Enter an Integer (1–1000000) or type x to exit: "); fgets(buffer, 100, stdin); /*getting the decimal value from calling the method*/ Decimal=getInteger(buffer); /*if user inputs x then getInteger return -1*/ if(Decimal == -1){ printf("Goodbye! "); /*terminating the program*/ break; } printf("Decimal: %d ", Decimal); printf("Hexadecimal: %x ", Decimal); printf("Octal: %o ", Decimal); long x = DecimaltoBinary(Decimal); printf("Binary: %ld ",x); printf("Save to file?
