i like scripting you can use this source code
/* Source code to create a simple calculator for addition, subtraction, multiplication and division using switch...case statement in C programming. */
# include <stdio.h>
int main()
{
char operator;
float num1,num2;
printf("Enter operator either + or - or * or divide : ");
scanf("%c",&operator);
printf("Enter two operands: ");
scanf("%f%f",&num1,&num2);
switch(operator)
{
case '+':
printf("num1+num2=%.2f",num1+num2);
break;
case '-':
printf("num1-num2=%.2f",num1-num2);
break;
case '*':
printf("num1*num2=%.2f",num1*num2);
break;
case '/':
printf("num2/num1 = %.2f",num1/num2);
break;
default:
/* If operator is other than +, -, * or /, error message is shown */
printf("Error! operator is not correct");
break;
}
return 0;
}
Enter operator either + or - or * or divide: /
Enter two operands: 13.456
4.56
num2/num1 = 2.95
