Concepts:
Use of the function printf to format the output

Text:
Given a float variable:

float x = 12.12;

Produce the following output:

12.120000
12.120000
 12.120000
12.12
     12.12
0000012.12

Solution:

printf_format.c

/* Example of Use of the function printf to format the output */
 
#include <stdio.h>
 
 
int main(){
  float x = 12.12;
 
  printf("%f\n", x);
  printf("%4f\n", x);
  printf("%10f\n", x);
  printf("%.2f\n", x);
  printf("%10.2f\n", x);
  printf("%010.2f\n", x);
 
  return 0;
