Menu Driven Program to perform all arithmetic operations:

while(True):             print(“1. Add”)             print(“2. Subtract”)             print(“3. Multiply”)             print(“4. Divide”)             print(“5. Quit”)               ch = int(input(“enter choice :”))             if(ch==1):                         print(“Enter 2 numbers:”)                         a=int(input())                         b=int(input())                         print(“Res : “, a+b)             elif(ch==2):                         print(“Enter 2 numbers:”)                         a=int(input())                         b=int(input())                         print(“Res : “, a-b)             elif(ch==3):                         print(“Enter 2 numbers:”)                         a=int(input())                         b=int(input())                         print(“Res : “, a*b)             elif(ch==4):                         print(“Enter 2 numbers:”)                         a=int(input())                         b=int(input())                         print(“Res : “, a/b)             elif(ch==5):                         break             else:                         print(“Invalid choice”)
