#### Topic: [new user] Compile/build a pure C code (How to?/Examples?)

Hello,

I am a new user of SF.

I could successfully compile Fortran code. I would like now to compile a pure C code. I tried it with a simple code (see below) but it didn't work. Could you please give me a feedback, why this simple code doesn't work?

Thank you in advance,

Peter

/* Program quad_root.c */

#include <math.h>

main(){

float a, b, c;

float xl, x2;

float D;

printf("Enter coefficient a:");

scanf("%f",&a);

/* test for quadratic */

if (a==0){

printf("Illegal quadratic!\n");

exit(0) ;

}

printf("Enter coefficient b:");

scanf("%f",&b);

printf("Enter coefficient c: " ) ;

scanf("%f",&c);

/* Compute argument for square root and

test for complex roots */

D = b*b - (4*a*c);

if(D < 0){

printf("complex roots! \n");

exit(0);

}

/* Compute roots of quadratic*/

xl = (-b-sqrt(D))/2*a);

x2 = (-b+sqrt(D))/(2*a);

/* Output the results*/

printf("xl = %f\n",xl);

printf("x2 = %f\n",x2);

exit(0);

}
