#include<stdio.h>
main()
{
int a,b,c;
char ch;
printf("Enter two nos");
scanf("%d%d",&a,&b);
printf("Enter the operator for the specific operation");
scanf(" %c",&ch);
switch(ch)
{
 case '+':c=a+b;
        printf("Addition=%d",c);
break;

 default:printf("Invalid Character");
}
}

ASSIGNMENT 3)

TO DEMONSTRATE DECISION MAKING STATEMENTS (SWITCH CASE)

You should read following topics before starting this exercise

1. Different types of decision-making statements available in C.
2. Syntax for switch case statements.

The control statements that allows us to make a decision from the number of choices is called a switch-case statement. It is a multi-way decision making statement.

i) Usage of switch statement
   
    Syntax:  switch(expression)
                    {
                   case value1: block1;
                      break;
                   case value2: block2;
                      break;

                         . 

                         . 

                    default: default block;

                      break;

                   }

ii) The switch statement is used in writing menu driven programs here a menu displays several options and the user gives the choice by typing a character or number .
