Objective: Create a C program to calculate the distance between the edges of two circles given their radii and positions. Requirements Declare Circle Structure: Create a structure named Circle with the following members: Floating-point radius Floating-point x_position Floating-point y_position Declare and Define Function: Create a function named distance_between that takes two parameters, both of type struct Circle. The function should return a float value. The function must compute the distance between the edges of the two circles and return it. Formula: Distance= sqrt( (x1 - x2) ^2 + (y1 - y2)^2) - r1 - r2 Where: (x1,y1)(x1,y1) and (x2,y2)(x2,y2) are the coordinates of the centers of the two circles. r1r1 and r2r2 are the radius of the two circles. Input Result 2 3 distance between two circle is 12.464249.

Get vowels in strings

This method gets vowels (‘a’, ‘e’, ‘i’, ‘o’, ‘u’) found in a string.
   
#make a function:
def get_vowels(string):

#return is the keyword which means function have to return value: 
 return [each for each in string if each in 'aeiou']


#assign the words and function will return vowels words.
get_vowels('foobar') # ['o', 'o', 'a']


get_vowels('gym') # []

#python #function

Python when function - to apply a function when predicate(x) is True

def when(predicate, when_true):
  return lambda x: when_true(x) if predicate(x) else x
  
EXAMPLES
double_even_numbers = when(lambda x: x % 2 == 0, lambda x : x * 2)
double_even_numbers(2) # 4
double_even_numbers(1) # 1

#python #lists #function

Build a list using an iterator Python unfold function

def unfold(fn, seed):
  def fn_generator(val):
    while True: 
      val = fn(val[1])
      if val == False: break
      yield val[0]
  return [i for i in fn_generator([None, seed])]
  
  
EXAMPLES
f = lambda n: False if n > 50 else [-n, n + 10]
unfold(f, 10) # [-10, -20, -30, -40, -50]

How to use the fgets() function in C

#include <stdio.h>

int main(){
  char str[20];
  
  fgets(str, 20, stdin); // read from stdin
  puts(str); // print read content out to stdout
  
  // open the file
  FILE *f = fopen("file.txt" , "r"); 
  
  // if there was an error
  if(f == NULL){
    perror("Error opening file"); // print error
    return(-1); 
  }
  // if there was no error
  else{ 
    fgets(str, 20, f); // read from file
    puts(str); // print read content out to stdout
  }
  
  fclose(f); // close file
  
  return(0);
}
