    Hi everyone can someone help me write this bar chart idk how to write it

    Problem Description

    Write a program to display a bar chart of the input data.

    [Input form]

    Read multiple (not more than 30) positive integers (greater than 0 and less than or equal to 20) from standard input, ending with -1. Separate each integer with a space.

    【Output form】

    The histogram of each number is displayed on the screen in turn (the "*" character represents the histogram, and the blank space is represented by space characters).

    【Sample input】

    5 12 8 6 1 4 -1

    [Sample output]

    **** *
    **** *
    **** *

    [Sample description]

    A total of 6 positive integers were entered, namely: 5 12 8 6 1 4. Therefore, the leftmost column should output 5 bars denoted by "*", followed by 12, 8, 6, 1, and 4 bars denoted by "*".

    Make an effort.
    Just dumping your assignment isn't good enough.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Here's a hint:

    The problem statement explicitly calls for column displays. And it appears to require the columns to correspond directly to the numbers entered. So you cannot reorder the numbers into ascending order or anything.

    Therefore, make a 2-d array of chars, and fill it with either stars or spaces. Then you can quickly output the array without worrying about what it contains, whether it is too high or too low, or anything like that.

    This lets you separate out the "printing" from the "computing." It should make things easier for you.
