C Program that receives a number and prints it out in large size

Given a number n in form of a string; the task is to print that following number in large using hash symbols.

Like we have provided a number “1234”

The representation of the following number should be −

Likewise we want our solution to be printed −

Example

Input: n[] = {“2234”}
Output:

Input: n[] = {“987”}
Output:

Approach we will be using to solve the given problem −

• Take at most 4 digit number a input in a string.
• Make arrays of every number one by one the large pattern we want for the number.
• Traverse the string and print every number one by one.
