function based calculator program in C | download pdf -oklesson

If you have read the function in C, and all your doubts have become clear, then this post is for you today, because in this post you can learn how to make a function based calculator.  This means that we will break the calculator into small functions, including Add () function, Subtract () function, Multiply () function, and Divison () function. Writing a program like this is called modular programming, in which we divide a large program into small parts, and then give those parts as a function, and then we call those functions according to our function. Let's do it.

Function Based calculator In C

 Writing code in this way does not make the code too tough, and this code will be easily understood by everyone. To create this calculator, we have covered the concept of complete function, in this calculator we will also pass the argument, and also return the value. And you can also download its pdf. This calculator is completely dependent on the user, which means that it will continue to operate as long as the user wants, to run this calculator again and again, we have used a while loop.

In which function based program we have also put a condition. The program will end when the condition is false. And according to the operation of the user, we will check the given value, which operation the user wants to perform.

  <!-- #include<stdio.h> /*Add function takes two Arguments , you Also change variable name, if you want*/ int Add(int a,int b) { int c; c=a+b; return c; //return value of c } /*Sub function takes two Arguments , you Also change variable name, if you want*/ int Sub(int a,int b) { int d; d=a-b; return d; //return value of d } /*Mul function takes two Arguments , you Also change variable name, if you want*/ int Mul(int a,int b) { int e; e=a*b; return e; //return value of e } /*Sub function takes two Arguments , you Also change variable name, if you want*/ int Div(int a,int b) { int f; f=a/b; return f;//return value of f } int main() { int a,b,choice; char ch; do{ printf("\nEnter Two Number\n"); scanf("%d%d",&a,&b); printf("\nChoose operation(choose only option number) :..\n1.Addition\n2.Subtraction\n3.Multiply\n4.Divison\n5.All of The Above\n6.exit\n"); scanf("%d",&choice); if(choice==6){ break; } else { switch(choice) { case 1: printf("\n\nThe Addition of %d and %d is = %d\n",a,b,Add(a,b)); break; case 2:printf("\n\nThe Subtraction of %d and %d is = %d\n",a,b,Sub(a,b)); break; case 3:printf("\n\nThe Multiply Of %d and %d is = %d\n",a,b,Mul(a,b)); break; case 4:printf("The Divison Of %d and %d is = %d\n",a,b,Div(a,b)); break; case 5: printf("\n\nThe Addition of %d and %d is = %d\n",a,b,Add(a,b)); printf("\n\nThe Subtraction of %d and %d is = %d\n",a,b,Sub(a,b)); printf("\n\nThe Multiply Of %d and %d is = %d\n",a,b,Mul(a,b)); printf("\n\nThe Divison Of %d and %d is = %d\n",a,b,Div(a,b)); break; default:printf("\nOoop's not Matched\n"); }} printf("\nDo you want to perform Another operation\n y for YES \n n for NO\n"); fflush(stdin); scanf("%c",&ch); }while(ch=='y'); } --> By looking at this program, you must have understood how this program will work, you can add as many functions as you want to this program, and you can use them according to your work.
