Thread: looking for some maths examples in c ?

The general rule is to have a reasonable consistency, i.e., to use a consistent indent style with a consistent number of spaces or a single tab per indent level. There are a few common indentation styles: Wikipedia article on indent styles. The first two in the table shown in the article are the most common; I suggest that you pick one of the two.

Thank you for your comments. I reviewed the Wiki, and will adopt Allman style.

can i get a good working example of a c program solving quadratic equation ?

every example i try is ending up in some errors ...

thanks for that ...

i have already tried atleast 12 examples from different places ... everything is giving me errors in my favorite online compiler ... i like that compiler , which is why i keep using it ... i want to see a quadratic equation program in c , succesfully working in that compiler ...

let me see if i can find a proper example working in that compiler ...

i finally found a proper working example ...

Code:

        #include<stdio.h>
        #include<math.h>
         
        int main(){
          float a,b,c;
          float d,root1,root2;  
         
         
          printf("Enter a, b and c of quadratic equation: ");
          scanf("%f%f%f",&a,&b,&c);
           
          d = b * b - 4 * a * c;
          
          if(d < 0){
            printf("Roots are complex number.\n");
         
            printf("Roots of quadratic equation are: ");
            printf("%.3f%+.3fi",-b/(2*a),sqrt(-d)/(2*a));
            printf(", %.3f%+.3fi",-b/(2*a),-sqrt(-d)/(2*a));
          
            return 0; 
          }
          else if(d==0){
           printf("Both roots are equal.\n");
         
           root1 = -b /(2* a);
           printf("Root of quadratic equation is: %.3f ",root1);
         
           return 0;
          }
          else{
           printf("Roots are real numbers.\n");
          
           root1 = ( -b + sqrt(d)) / (2* a);
           root2 = ( -b - sqrt(d)) / (2* a);
           printf("Roots of quadratic equation are: %.3f , %.3f",root1,root2);
          }
         
          return 0;
        }
