Program to print all three digit numbers in ascending order

Write a program to print all the three-digit numbers in ascending order.

:

100 101 102...till 999

Approach: Using for Loop to print all the three Digit Numbers:

Use for loop to iterate from the smallest three-digit number, that is 100 till we reach the largest three-digit number, that is 999 and, in every iteration, print the number. After reaching 999, we will have all the three-digit numbers in ascending order.

Step-by-step algorithm:

• Initialize a counter to the smallest 3-digit number i.e. 100.
• Run a for loop till the greatest 3-digit number i.e. 999.
• For each iteration print the number

Below is the implementation of the above approach:

All three digit numbers in ascending order: 
100
101
102
103
104
105
106
107
108
109
