count the most frequent letter in string permutation example : if x = icyz and j = ixpc, then there are 8 different passwords that you can choose: icyz,icyc, icpz, icpc, ixyz, ixyc, ixpz, ixpc. icpc has the most frequent letter so the output is 2 please help with c++ code (studio.h, string.h,math.h only)

Using C#, create an application that will ask the user to enter passwordset in the program for only three times. Once the user fails to enter the correct passwordfor three consecutive times, he/she will not be able to proceed with the quiz. The quizshould contain at least five questions about a hobby, popular music, astronomy, or anyother personal interest. The question should be in multiple choice and responses couldbe a, b, c, or d. After answering all the questions, the total number of correct answersshould appear immediately.

public getFuelLevel():double retrieves fuel level in gallons Precondition: fuel level is initialized Postcondition: no change in state Return: fuel level in gallons with decimal valuespublic getFuelTankSize():double retrieves fuel level in gallons Precondition: fuel level is initialized Postcondition: no change is state Return: fuel level in gallons with decimal valuespublic setUpTrip(double, double): void Car's state is set to hold the speed of travel and distance to travel at that speed Precondition: none Postcondition: Car's state holds information on distance to travel and speed to travel Parameters: Average Speed to be driven, Distance to driveDevelop and use an algorithm that calculates the amount of fuel used and the actual distance driven in the drive() method. The algorithm must use a formula or multiple formulas ( as a piecewise function) that gives proportionately poorer mileage when the Car is driven faster or slower than its optimal speed.

Assign interestPointer with the address of the higher interest. If the interests are the same, then assign interestPointer with nullptr. Ex: If the input is 497 261, then the output is: 497 is the higher interest. #include <iostream>using namespace std; int main() { int interest1; int interest2; int* interestPointer; cin >> interest1; cin >> interest2; /* Your code goes here */ if (interestPointer == nullptr) { cout << "The interests are the same." << endl; } else { cout << *interestPointer << " is the higher interest." << endl; } return 0;}
Each of the following files in the Chapter.07 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem, and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, DebugSeven1.cs will become FixedDebugSeven1.cs. a. DebugSeven1.cs b. DebugSeven2.cs c. DebugSeven3.cs d. DebugSeven4.cs
Each of the following files in the Chapter.04 folder of your downloadable student files has syntax and/or logical errors. In each case, determine the problem, and fix the program. After you correct the errors, save each file using the same filename preceded with Fixed. For example, save DebugFour1.cs as FixedDebugFour1.cs. a. DebugFour1.cs b. DebugFour2.cs c. DebugFour3.cs d. DebugFour4.cs
