in This I Will Explain What is Switch Statement in computer programming Language ? and how we can make a simple calculator using c programming Language full Guide in English language if you are a computer student and learning programming language then you must know how to make calculator with the help of  switch statement in programming language.

How to create calculator in c programming??

So first of all you know the switch statement because in program we use the switch statement.

switch statement means Tests the values of a variable and compares the multiple cases.

so next we come to the program we use the code block you use the anther software like  

turbo c++ or dvc++.

so first i will write the program than i will explain Cleary step by step

program

#include<stdio.h>

#include<conio.h>

main()

{

 float num1;

 float num2;

 char op;

 float result;

printf("enter the first number:");

scanf("%f",&num1);

printf("enter the operation:");

scanf("%c",&op);

printf("enter the second number:");

scanf("%f",&num2);

switch(op)

{

case'-':

result=num1-num2;

printf("%f",result);

break;

case'+':

result=num1+num2;

printf("%f",result);

break;

case'*':

result=num1*num2;

printf("%f",result);

break;

case'/':

result=num1/num2;

printf("%f",result);

break;

 

default:

printf("the operator is not valid:");

}

getch();

} 

out put

enter the first number : 10
enter the operation : +
enter the second number: 10
20.0000

enter the first number:17

enter the operation: -

enter the second number:16

1.00000

 

So like that . so first we include the header file #include<stdio.h> and anther one is #include<conio.h>

so next we write the main function. so after that we include variables right. so float num1,and float num2, these are main two variable. so next one char op;

because we choose the operation like addition ,subscription, and multiplication or division so like that we choose operation. so next we write the float result .result means display .

next we print enter the first number and scanf %f and print the num1,

next we print the operation %c ,and print the second number and we write the scanf %f&num2

here we use the switch statement . in switch we use the CASE  so our first case is - ,in this we 

write num1-num2 like that .  

so like this we use anther +,*.\ in multiplication we use the star mark. its remember.

So lastly we add default : next we print the operation is not vailed :

so complete our calculator program. so i hope you like it . in any dotes in the  program you can comment the comment section .I will replay earliest.
