write a program thats prompts the user to enter a person's date of birth in numeric form such as 8-27-1980. the program then outputs the date of birth in the form: august 27, 1980. Your program then outputs the date of birth in the form: august 27, 1980. Your program must contain to classes: invalidDayException and invalidMonthExcep. if users enter an invalid value for a day, then the program should throw and catch and InvalidDayExcept object. similar conventions for the values of month and year.

User will be able to view the blood available in all blood banks b. User can transfer blood from one bank to another bank or hospital as per that updation in the quantity should happen c. Delete the blood details if it is expired 

Please put Try Another[Y/N]:

here in this code.

#include <iostream>

using namespace std;

int main(){

int i;

cout<<"Input i: ";

cin>>i;

cout<<"Process = ";

int fact = 1;

int n = 1;

for(int x=i; x>=1; x--){

fact *= x;

cout<<n <<"*";

n++;

}

  cout<<"\nOutput: "<<fact<<endl;

}

Create a C program and a flowchart that will generate a table of chosen mathematical operations. The user has to be prompted first for the math operation and then enter a value that will be used to add, subtract, multiply or divide from 1 to 10 to complete the table. A sample run is provided below to illustrate the output.

M A T H O P E R A T I O N S:

[M] – Multiplication

[D] – Division

[A] – Addition

[S] - Subtraction

Enter your choice: M
