Users of this program can carry out addition, subtraction, multiplication, and division, among other fundamental arithmetic operations.
Two numbers will be entered by the user, who will also select an operation by typing a symbol (+, -, *, /).
To carry out the action in accordance with the user’s selection, we’ll employ a switch-case statement.
#include <stdio.h>
int main() {
float num1, num2, result;
char operator;
// Asking user for the first number
printf("Enter first number: ");
scanf("%f", &num1);
// Asking user for the second number
printf("Enter second number: ");
scanf("%f", &num2);
// Asking user for the operation they want to perform
printf("Enter operator (+, -, *, /): ");
scanf(" %c", &operator);
// Performing the chosen operation
switch (operator) {
case '+':
result = num1 + num2;
break;
case '-':
result = num1 - num2;
break;
case '*':
result = num1 * num2;
break;
case '/':
result = num1 / num2;
break;
default:
printf("Invalid operator\n");
return 1;
}
// Displaying the result
printf("Result: %.2f\n", result);
return 0;
}
