int choice;
printf("Enter 1st Number: ");
scanf("%f",&num1);
printf("Enter 2nd Number: ");
scanf("%f",&num2);
printf("1.sum 2.difference 3.product 4.subtraction\n");
printf("Please select: ");
scanf("%d",&choice);
if(choice==1) printf("%f",num1+num2);
else if(choice==2) printf("%f",num1-num2);
else if(choice==3) printf("%f",num1*num2);
else if(choice==4) printf("%f",num1/num2);
return 0;
