Write in C++ Sam is making a list of his favorite Pokemon. However, he changes his mind a lot. Help Sam write a function insertAfter() that takes five parameters and inserts the name of a Pokemon right after a specific index. Function specifications Name: insertAfter() Parameters (Your function should accept these parameters IN THIS ORDER): input_strings string: The array containing strings num_elements int: The number of elements that are currently stored in the array arr_size int: The number of elements that can be stored in the array index int: The location to insert a new string. Note that the new string should be inserted after this location. string_to_insert string: The new string to be inserted into the array Return Value: bool: true: If the string is successfully inserted into the array false: If the array is full If the index value exceeds the size of the array

Using C++ Language In this program you will write a function of void return type named compare that accepts an integer parameter named guess. This function will compare the value of guess with a seeded randomly generated integer between 1 to 100, inclusive, and let the user know what the random number was as well as whether the guess was larger than, smaller than or equal to the random number. NOTE THAT: You will NOT generate a random number inside the compare function. Rather, you will write another function named getRandom of int return type to do it. You will need to call getRandom from compare, no parameters are necessary. Inside your main function, get the guess from user and pass it to the compare function. Code: #include <iostream>using namespace std; int getRandom(){ //generate seeded random num. //in between 1-100 inclusive //return random number } void compare(int guess){ //call getRandom //compare guess with random number //inform user what…
