Calculator bnane ka C program (कैलकुलेटर बनाने का C प्रोग्राम )

Is post mai calculator bnane ka bhut hi simple C program bnaya hai (Making C program for calculator). Agar app beginner hai to is c program se apke kafi doubt bhi clear ho jayege. Calculator ke liye program bnana ek useful trick hai.

 (1). Calculator  का C Program 

Is program se ham Addition(+), Subtraction(-), Multiplication(x), Division(/) bhut asani se kar skte hai.
Calculator ke lye program ham switch statement ka use karke bnayege. 
Mene yah program Dev C++ software mai bnaya hai.


C Programming for Calculator :

        This code prepared by Electronics & Technology (Rajendra singh), www.elextechnologys

                 
     #include<stdio.h>
    int main()
          
    {
            
    int number_1, number_2;              // ये integer  वेरिएबल हैं 
   
    float Answer;                        // ये float वेरिएबल हैं 

    char operation;                      //to store operator choice, char वेरिएबल   

     

    printf("Enter first number: ");  

    scanf("%d",&number1);

    printf("Enter second number: ");

    scanf("%d",&number2);

     

    printf("Choose operation to perform (+,-,*,/,%): ");

    scanf(" %c",&operation);
 

    result=0;

    switch(operation)    

    {

        case '+':              // जोड़ 

           Answer =number_1+number_2;

            break;

             
        case '-':               // घटाना 

           Answer = number_1-number_2;


            break;
        

        case '*':              // गुणा 

           Answer = number_1*number_2;

            break;
     

        case '/':              // भाग 

           Answer = number_1/number_2;


            break;

             
        case '%':           //भाग का शेषफल 

           Answer = number_1%number_2;


            break;

        default:           // गलत key press होने पर  

            printf("Invalid operation.\n");

    }

    printf("Result: %d %c %d = %f\n",number_1,operation,number_2,operation);
    


return 0;




   }  // 🙏🙏🙏🙏🙏🙏🙏 प्रोग्राम खत्म हुआ 

Calculator bnane ke liye apko iss code ko copy past krna hoga. Iske bad ise run krna hoga. Run hone pe apko do value print krani hogi iske bad jo bhi operation (+, -, *, /, %) krna  use print krna hoga jiska result display mai show ho jayega.

Output                  

First round run

Enter first number:    25

Enter second number:    15

Choose operation to perform (+, -, *, /, %):    '+'
 Result :   25+15   =    40.000

Second round run

Enter first number:    20

Enter second number:    5 

 Choose operation to perform (+, -, *, /, %):   '*'

 Result :   25*15   =    375.000

Upper diya huaa C program ko Switch Statement ka use krke bnana gya hai. Ye program bhut hi simple hai.
