# How to fill a number with a variable amount of 0s?

This might help you I'm trying to print a number with a certain amount of zeros before it. I know that in order to print a constant amount of zeros I need to
code :
``````#include <stdio.h>

int main(void) {
int alpha = 1;
int beta = 23456;
int spacing = 3;

printf("Alpha: %0*d\n", spacing, alpha);

spacing = 8;
printf("Beta:  %0*d\n", spacing, beta);
return 0;
}
``````
``````Success #stdin #stdout 0s 4372KB
Alpha: 001
Beta:  00023456

## Fill with variable number of ones

this one helps. What's the best way to fill a variable with an unknown (at compile time) number of ones? For example, let's say: , You can use left shift and then subtract 1:
code :
``````unsigned int b = (1U << n) - 1U;

// Broken down into steps
//  1           = 00000001b
//  1 << 5      = 00100000b
// (1 << 5) - 1 = 00011111b

this one helps. You're probably looking for box-sizing (it can be a real gamechanger once applied to every element on the page like below):
code :
``````* {
box-sizing: border-box;
}

I hope this helps you . I'm looking to 0-pad a string before I display it to the user, e.g. , You can use the :0_ format specifier with a variable:
code :
``````println!("{:0width\$}", x, width = width); // prints 001234
``````
``````000000000000000000000000000000000000000000000000000000001234
``````
``````println!("{:01\$}", x, width);
``````

## ggplot2 - 2 variable clustered column chart - gradient fill for variable 1 and solid fill for variable 2

this will help I have the below data that I would like to create a clustered column chart from. Note this is dummy data. , Full warning this is starting to get a little hacky, but here we go:
code :
``````ggplot(dataraw, aes(x = CRITERIA, y = ACTUAL, fill = EFFORT)) +
scale_fill_gradient(low = "blue", high = "red") +
geom_col(aes(y = FUTURE), fill = "black", width = .4, position = position_nudge(.2)) +
geom_col(width = .4, position = position_nudge(-.2))
``````
