Thread: can't find the error

I am a newbie to programming, i started with c programming as many people said it is a good idea to start with c or c++. Anyway, i was writing this code but i keep getting error on the last else. i looked everywhere i can't find the error. the message is not clear (or i don't understand what it means). can you look at this code and tell me what is wrong? thank you

Code:

#include <stdio.h>
#include <stdlib.h>

/*SIMPLE PROGRAM FOR FINDING REAL ROOTS OF THE EQUATION: ax2+bx+c=0*/
 
int main()
{
 float a,b,c,x1,x;
 printf("enter a, b, c separated by space\n");

 scanf("%f%f%f",&a,&b,&c);

 if (a==0&&b==0)

    printf("No root"); 

 else if(a==0)
 
  
  printf("there is only one root %f",-c/b);

 else if ((b*b-4*a*c)<0) 

    printf("No root");
 
else {
    x1=-b+((b*b-4*a*c)/2)2*a;   

    x=-b-((b*b-4*a*c)/2)2*a;

    printf(" X1 is %f, X is %f",x1,x);
}
getchar();
 
    return 0;
}

You are missing one * before 2.

thank you, that was the mistake.

@endrick - when learning to program it's a good idea to also learn compiler messages. I know they look confusing and scary to a beginner at first sight - but a lot of them are pretty straight forward, and even if not, once you know how to read them, they are good help in spotting errors. I suggest next time you don't make do by stating "I get an error", but instead come up with the actual error message and let people help you understand it.

thank your for the advice. i will
