Introduction
Write C program to create calculator using switch Statement
# include <stdio.h> int main() { char operator; double firstNumber,secondNumber; //Reading operator from user printf("Enter an operator (+, -, *,): "); scanf("%c", &operator); //Reading operands from user printf("Enter two operands: "); scanf("%lf %lf",&firstNumber, &secondNumber); switch(operator) { case '+': printf("%.1lf + %.1lf = %.1lf",firstNumber, secondNumber, firstNumber + secondNumber); break; case '-': printf("%.1lf - %.1lf = %.1lf",firstNumber, secondNumber, firstNumber - secondNumber); break; case '*': printf("%.1lf * %.1lf = %.1lf",firstNumber, secondNumber, firstNumber * secondNumber); break; case '/': printf("%.1lf / %.1lf = %.1lf",firstNumber, secondNumber, firstNumber / secondNumber); break; // operator doesn't match any case constant (+, -, *, /) default: printf("Error! please enter correct operator"); } return 0; }
