void find_replace (string & text, const string& find_str, const string& replace_str); Find and Replace is an extremely useful tool built into text editors, spreadsheets, Google docs, word processors, and many other apps. This function takes three strings as parameters: ● ● ● text: this is the original text that will be searched and potentially adjusted. find_str: this is the substring the function will search in text. replace_str: if find_str is found in text, this is the substring that will be used to replace the find_str substring. The function is to replace all occurrences of find_str in text with replace_str. To simplify the problem, only the exact match for find_str will be replaced. In addition, you may assume that replace_str does not contain find_stras its substring. The following illustrates the result of some sample testing of the function. text BEFORE aba baab aba baab aba baab aba baab aba baab find_str a aa ab ba bb replace_str cd cd cd cd cd text AFTER cdbcd bcdcdb aba bcdb cda bacd acd cdab aba baab

Objectives: In program C. NOT C++ or python • How to use the random number generation. • How to call function and return data to the main function. • How to print in a tabular form. Write a program that simulate coin tossing. • For each toss of the coin the program should either prints Heads or Tails. • Let the program toss the coin 100 times, and count the number of times each side of the coin appears. • The program should call a separate function called “flip”, that takes no argument and returns 0 for tails and 1 for heads using random generator. • The program should print the result received either “Heads”, or “Tails”. • The print should be in tabular form 10 in a row on one line after another, see figure below. -The result should be completely random. In other words, the number of heads and tails should be different each time you run the program

C PROGRAM Create a c program that will convert number figures into words 1. You can use user-defined functions, string, array, and loops 2. Maximum input limit is 10000.00 Sample output (bold letters is for input) Enter amount in Peso: 143.50 You just entered P145.50 equivalent to One Hundred Forty Three and Fifty Centavos. Do you want to convert another amount? [Y|N]: N
