Program Plan Intro

Program to convert a decimal number into any base between “2” and “9”:

Program Plan:

• In “main()” function
  • Declare variables “stackk1” for stack, “base_to” for base to which convert and “numm” for number in decimal to be convert.
  • Read values for “base_to” and “numm” from user.
  • If base is between “2” and “9” and “numm” is greater than “0”,
    • Push the value of “numm” mod “base_to” into stack “stackk1”.
    • Then Divide “numm” by “base_to” and take this value as next “numm”.
    • Continue above two steps till “numm” becomes “0”.
  • Pop all numbers from “stackk1” and print it till “stackk1” becomes empty.
  • If base is not between “2” and “9”, print error message.

Program Plan Intro

Modified program to convert a decimal number into any base between “11” and “27”:

Program Plan:

• In “main()” function
  • Declare variables “stackk1” for stack, “base_to” for base to which convert and “numm” for number in decimal to be convert.
  • Read values for “base_to” and “numm” from user.
  • If base is between “11” and “27” and “numm” is greater than “0”,
    • Push the value of “numm” mod “base_to” into stack “stackk1”.
    • Then Divide “numm” by “base_to” and take this value as next “numm”.
    • Continue above two steps till “numm” becomes “0”.
  • Pop each number “ele” from “stackk1”
    • If “ele” is less than or equal to “9”, print itself.
    • If “ele” is greater than “9” and less than “27”, print character corresponding to ASCII value of “ele+55”
  • If base is not between “11” and “27”, print error message.
