Question

Error, please help correct

Answer 1

What did you change?

Answer 2

Chike Chewakondi please show us your attempt. I gather this is a c code but you attempted to put your code in the title verses the description part of the question section of the thread.

Answer 3

Instead of using multiple if else use switch case statements

Answer 4

Chike Chewakondi and BroFar , here's the right way to add code:
1. Enter the code in Code Playground
2. Save it as public
3. In the question description, tap "+" button
4. Select code
If you already posted the question, just edit it.
Also, use tags to inform the language. "please" and "really" give absolutely no information.

Answer 6

Bro, you can use these methods for clear keyboard buffer in c :-
1. scanf(" %c",&op);

2. fflush(stdin);
scanf("%c,&op);

Answer 7

Really sorry for that, thanks for the concern

Answer 8

I have difficulties to post that

Answer 9

Can you grab a copy and post it here in the thread so we can see how to help you? Chike Chewakondi

#include<stdio.h>
int main(){
printf("MY SIMPLE CALCULATOR");
printf("\nInstructions");
char name[50];
printf("\n Enter your name:");
gets(name);
printf("\n\n %s,To perform an operation,Enter 1""\n -and,To perform a summation,""Enter 2:",name);
int option;
scanf("\n%d",&option);

if(option==1){
printf("\n You have chosen option=%d,%s",option,name);
printf("\n So,To perform an operation for only two numbers,Enter one of the following operators");
char operator;
printf("\n [+,-,*,/]");
printf("\n Operator:");
scanf("%c", &operator);
double num1,num2;
printf ("\n %s,Please enter first number value:",name);
scanf("%lf",&num1);
printf ("\n and second number value:");
scanf("%lf",&num2);
double result;
switch(operator){
case '+':
result=num1+num2;
printf("\n%s, your result is %.1lf", name,result);
break;
case '-':
result=num1-num2;
printf("\n%s, your result is %.1lf",name,result);
break;
case '*':
resul

Answer 11

Looks like you need to have knowledge of all inputs ahead of time Chike Chewakondi and enter them in the beginning.

Answer 12

So how do l go about

Answer 13

I thought it was just exactly there we had to input a value, but it always seemed to skip that line

Answer 14

Chike Chewakondi first error change gets to scanf("%s", &name);
1 error down

option 1 and option 2 seem to be fine

it doesn't appear to be picking up the operator

num1 and num2 appear to be floats try it with int as %d vs %lf

not sure if you have other inputs / scanf(s) I missed.

Answer 15

What if the inputted num values are decimal points

Answer 16

It's still skipping the operator read part, what do you propose sir

Answer 18

Thanks for the tip but if you remove the part of my code which operates, it works well but when you insert that in another conditional, the problem starts

Answer 19

#include<stdio.h>

int main()
{
printf("MY SIMPLE CALCULATOR");
printf("\n To perform an operation"
"\n Enter one of the following operators");
printf("\n [+,-,*,/]");
char operator;
printf("\n Operator:");
scanf("%c",&operator);
double num1,num2;
printf ("\n Enter first number value:");
scanf("%lf",&num1);
printf("Num 1= %lf",num1);
printf ("\n Enter second number value:");
scanf("%lf",&num2);
printf("\nNum 2= d%",num1);
double result;
printf("\n The result is %lf",result);
switch(operator){
case '+':
result=num1+num2;
printf("\n The result is %lf",result);
break;
case '-':
result=num1-num2;
printf("\n The result is %lf",result);
break;
case '*':
result=num1*num2;
printf("\n The result is %lf",result);
break;
case '/':
result=num1/num2;
printf("\n The result is %lf",result);
break;
default:
printf("Invalid input");
}
return 0;
}
As this
