its C programming language problem

Problem 1

a) First program in C

We are going to create a calculator that performs the basic operations. You need three inputs: two floating numbers and the operator. The available operators are: + addition - subtraction * multiplication / division

b) Type of variables and updating variables

// this is code please complete my code

#include

int main() { // Declare variables /* Complete here */

// Scan inputs /* Complete here */

// Perform the operation // First, we have to use an if or switch statement to know which operation we want to perform switch (operation){ case '+': // Complete here

break; case '-': result = a - b; break; case '/': if (b == 0){// we can not divide by 0 printf("It is not possible to perform the operation "); return 0; // Here we stop the program inmediately } else { // Complete here } break; case '*': // Complete here break; } printf("The result is: %.3f ", result); return 0; }
