Calculator Program in C language | part 7 = total programming

                                                                    Calculator Program

Hello guys, in this post I am going to give you a practice program which is an ATM program it is very simple which not include any graphics.

so let us move on to the program.

Source code =

#include<stdio.h>

#include<conio.h>

void main()

{

      

        float ch,ad1,ad2,sb1,sb2,mt1,mt2,di1,di2;

    

        printf("\n\t\nplease enter what you want to do in calculator");

    

        printf("\n\t1.Addition");

        printf("\n\t2.Subtraction");

        printf("\n\t3.Multiplication");

        printf("\n\t4.Division");

    

        printf("\n\n\tEnter your Choose= ");

        scanf("%f",&ch);

    

        if (ch==1)

        {

            printf("\n\tenter the first digit= ");

            scanf("%f",&ad1);

        

            printf("\n\tenter the second digit= ");

            scanf("%f",&ad2);

        

            float ans1=ad1+ad2;

        

            printf("\n\tAnswer= %f",ans1);

            printf("\n\tAddition is done");

        

        }else if (ch==2)

        {

            printf("\n\tenter the first digit= ");

            scanf("%f",&sb1);

        

            printf("\n\tenter the second digit= ");

            scanf("%f",&sb2);

        

            float ans2=sb1-sb2;

        

            printf("\n\tAnswer= %f",ans2);

            printf("\n\tSubtraction is done");

        

        }else if (ch==3)

        {

            printf("\n\tenter the first digit= ");

            scanf("%f",&mt1);

        

            printf("\n\tenter the second digit= ");

            scanf("%f",&mt2);

        

            float ans3=mt1*mt2;

        

            printf("\n\tAnswer= %f",ans3);

            printf("\n\tMultiplication is done");

            

        }else if (ch==4)

        {

            printf("\n\tenter the first digit= ");

            scanf("%f",&di1);

        

            printf("\n\tenter the second digit= ");

            scanf("%f",&di2);

        

            float ans4=di1/di2;

        

            printf("\n\tAnswer= %f",ans4);

            printf("\n\tDivision is done");

        }

    

}
