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: ●くろまる ●くろまる ●くろまる 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

The Card Box Problem C++ you should write documentation for your program. Using functions, write a program that prompts the user to enter the area of the flat cardboard. The program then outputs the length and width of the cardboard and the length of the side of the square to be cut from the corner so that the resulting box is of maximum volume. Calculate your answer to three decimal places. Your program must contain a function that takes as input the length and width of the cardboard and returns the side of the square that should be cut to maximize the volume. The function also returns the maximum volume.
