Write a program in java that checks if an input string satisfies the following (error message is shown for each): At least 8 characters (Too short) At least one letter (Missing letter) At least one number (Missing number) At least one of these special characters: !, #, % (Missing special) Output OK, or all related error messages (in above order). If the input string is "Hello", the output is: Too short Missing number Missing special Hints: Declare a boolean variable for each requirement. Use a for loop to visit each character, setting the corresponding boolean to true if satisfied (length is done differently though). Use the functions Character.isLetter() and Character.isDigit() to detect if a character is a letter or a number. this is what i was able to do so far ......... Code starts here: import java.util.Scanner;public class Main { public static void…

- Language: C Concatenate two strings using pointers and dynamically allocating the memory for the results. Read two strings from the keyboard using the fgets function. Dynamically allocate the memory for the result using malloc function. Using pointers, copy the first string to the result , except the null terminator ( ’\0’) from the end from the first string. Copy the second string to the result, including the null terminator. Print your results. Free up memory with the free function. Use valgrind to check memory usage.Consider the following C++ structure and declarations: struct Player { string firstName; string lastName; int hits; int runs; }; int main() { Player p = { "Jackie", "Robinson", 1518, 947 }; Player team[24]; Player *tPtr = team; team[0] = p; // INSERT CODE HERE } The statement tPtr = team+9; will assign the same memory address to tPtr as the statement tPtr = &(team[9]); A) True B) FalseEmployee Salary Calculator Program and Analysis Demonstrate an understanding of C++ programming concepts by completing the following: Program: Create a C++ program that will function as an Employee Salary Calculator. Obtain from the user: Double variables for Standard Hours worked Rate of Pay Overtime Hours (if applicable) Calculate appropriate pay for standard hours and overtime (1.5 x rate of pay). Provide formatted output using the following methods setw() setprecision() Store the values into three different variables. For each double variable, create a double pointer to dynamic memory. Display the contents of the variables and pointers. In your program, be sure to use the new operator and delete operators to manage dynamic memory.

The first function named “functionWithArray” takestwo user input arguments of character types and return True if first argument is smaller than the secondargument (alphabetically) and returns False otherwise. Write the second function named“functionWithPointers” which behaves like the first functions but uses pointers to receive the arguments.You may assume that both character arrays contain only lower-case letters, and no blanks or other nonalphabetic characters. Write a suitable Main function to test these two functions.
