C Program To Perform Arithmetic Operation Using Switch Statement

    /*Write a c program to perform arithmetic

                default :
                        printf("Invalid choice\n");
                        break;

            }

    return 0;
}

Out Put:

Enter the two numbers :
5
4
1.Addition      2.Subtraction   3.Multiplication        4.Division
Enter the choice :
3
5 * 4 = 20
