C Program to Separate Digits of a Number

By 1 Min Read

The program below separates the digits of a five-digit number using C programming language.

Question: Write a program that inputs one five-digit number, separates the number into its individual digits and prints the digits separated from one another by three spaces each. [Hint: Use combinations of integer division and the remainder operation.] For example, if the user types in 42139, the program should print 4 2 1 3 9

* Program to separate the digits of a five-digit number.
*
*  Program Algorithm
*  -----------------
* declare variables to store user input(num) and each digits(dig1, dig2, dig3, dig4, dig5)
* read the user input e.g. 42139
* assign the last digit of the number to dig5 ie 9
* divide the number by 10 ie 42139/10 = 4213
* calculate the remainder and assign the value to dig4 ie 3
* divide the number by 10 ie 4213/10 = 421
* calculate the remainder and assign the value to dig4 ie 1
* divide the number by 10 ie 421/10 = 42
* calculate the remainder and assign the value to dig4 ie 2
* divide the number by 10 ie 42/10 = 4
* calculate the remainder and assign the value to dig4 ie 4
* print the digits separated by three spaces ie 4   2   1   3   9
