- Implement a function wordCount, which reads a text file, and returns thenumber of words in the file. You can assume the file only contains thealphabet characters and the space character. However there may be morethan one space character between two words, so “abc abc” and “abc abc”,for example, are both two words. int wordCount ( const char * filename ) {}Implement the following functions. Each function deals with null terminated C-Style strings. You can assume that any char array passed into the functions will contain null terminated data. Place all of the functions in a single file and then (in the same file) create a main() function that tests the functions thoroughly. Here are the functions: This function finds the last index where the target char can be found in the string. it returns -1 if the target char does not appear in the string. The function should be case sensitive (so 'b' is not a match for 'B'). int lastIndexOf(const char* inString, char target) This function alters any string that is passed in. It should reverse the string. If "flower" gets passed in it should be reversed in place to "rewolf". For efficiency, this must be done "in place", i.e., without creating a second array. void reverse(char* inString) This function finds all instances of the char 'target' in the string and replace them with…Write a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order. For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()
- Write a function that takes (i) a FILE pointer (e.g. FILE *fp) type variable, (ii) an array of student struct (that you defined in the previous question), and (iii) the number of valid elements in that array as parameters, and write those elements in a file named "students.dat". This function should return 1 if it can successfully open this file; otherwise, it should return 0.Please use C languageThis problem needs to be solved in python. Write a function read_movies_data(f) that takes in a movies file and returns a pandas DataFrame, where the index is the movie id and the columns are "title", "year", and "genre" (in that order). movies_df = read_movies_data("moviesSample.txt") assert movies_df.shape == (9, 3)assert movies_df.iloc[2, 2] == "Comedy"assert movies_df.loc[6, "title"] == "Heat"assert all(movies_df.columns == ["title", "year", "genre"])assert list(movies_df.index) == [1, 2, 3, 4, 5, 6, 8, 9, 10] NOTE: Make sure all of the asserts work The moviesSample.txt looks like this: 1|Toy Story|1995|Adventure2|Jumanji|1995|Adventure8|Tom and Huck|1995|Adventure3|Grumpier Old Men|1995|Comedy4|Waiting to Exhale|1995|Comedy5|Father of the Bride Part II|1995|Comedy6|Heat|1995|Action9|Sudden Death|1995|Action10|GoldenEye|1995|Action NOTE: Try to sent screenshots of the code working.Write a C/C++ program that: Writes a function, readFile(), that reads the content of the provided text file “stnumbers.txt” and stores it in an array of Student structs. The function receives as parameter an array of type Student structs. The number of lines that was read from the text file must be returned to the calling statement.

- The file text.txt contains a sentence text written in all small letters and does not have any punctuation marks, no numbers, no symbols except for spaces. You are required to write a program which accepts an operation code, and zero to two inputs depending on the operation code. Based on the operation code, you will call three versions of the overlaoded function textProcessing as follows: ● Operation 0: The function removes all vowels from the ORIGINAL sentence. The vowels considered are the small letters (a, e, i, o, u y, and w). • Operation 1: The code further asks for one lowercase letter to be input by the user. If the character is not a lower case letter, the code outputs Invalid.The function returns the distance (difference) between the letter first occurence and last occurence in the text. If the letter does not occur in the sentence, it returns 0. • Operation 2: The code asks for two lowercase letters to be input by the user. If the characters are not lower case letters, the…Write a function, named randomPassword, that generates a random password that takes noparameter. It will return the randomly generated password as its ONLY result. Display the randomlygenerated password in the main program. Password Criteria:o The password should have a random length of between 7 and 10 characters.o Each character should be randomly selected from positions 33 to 126 from the ASCII table. 1. You must import randint function directly and inline within the random package and it must be thefirst line of code in your program 2.Declaring and using FOUR constants 3. You must use the chr built-in function within your randomPassword function.4. Declaring the main function and invoking randomPassword function. 5.

- Write a program that creates a function to read multiple DNA sequences from the user and writes them in “Sequence.txt” file. Create another function that takes a string of DNA as argument and returns its transcribed sequence. Now read each sequence from Sequence.txt file, transcribe it, calculate its length & nucleotides frequencies. Store this modified information in a formatted way in another file named as “ModifiedSequences.txt”. In the end display contents of both the files.

The string can contain characters other than letters, but only the letters should be counted. The string could even be the empty string (just ""). Lower-case and upper-case versions of a letter should be part of the same count. The keys of the dictionary should be upper-case letters. If a letter does not appear in the string, then it would not get added to the dictionary. For example, if the string is "AaBb" then the dictionary that is returned should contain these key-value pairs: {'A': 2, 'B': 2} And no, we haven't covered the isalpha() funciton or the .get function, so don't use it.
