i need a debugger badly...

Code:

---

#include <stdio.h>
#include <math.h>

main()
{
  double first_a, first_b, second_a, second_b, ans1, ans2, ans3, ans4, ans5, ans6;
  printf("Test Complex Number Arithmetic");
  printf("\n");
  printf("Enter the first complex number in the form - real, imaginary - --> (");
  scanf(" ( %lf , %lf )", &first_a, &first_b );
  printf("\n");
  printf("Enter the second complex number in the form - real, imaginary - --> (");
  scanf(" ( %lf , %lf )", &second_a, &second_b );
  printf("\n");
  ans1 = (first_a + second_a, first_b + second_b);
  ans2 = (first_a - second_a, first_b - second_b);
  ans3 = (first_a * second_a, first_b * second_b);
  ans4 = (first_a / second_a, first_b / second_b);
  ans5 = (sqrt(first_a), sqrt(first_b));
  ans6 = (sqrt(second_a), sqrt(second_b));
  printf("Results:  (%lf) + (%lf) = (%lf)  (%lf) + (%lf) = (%lf)  (%lf) + (%lf) = (%lf)  abs(%lf) + (%lf) = (%lf)  abs(%lf) + (%i) = (%i)", first_a, first_b,
second_a, second_b, ans1, first_a, first_b, second_a, second_b, ans2, first_a, first_b, second_a, second_b, ans2, first_a, first_b, second_a, second_b, ans3, first_a,$

return 0;
}

Please explain what is wrong if you can. Any information that you have, like a sample run of your program, your compiler, your OS, and your expectations are valuable.

Code:

---

#include <stdio.h>
#include <math.h>

main()
{
  double a1, b1, a2, b2, a_ans1, b_ans1, a_ans2, b_ans2, a_ans3, b_ans3, a_ans4, b_ans4, a_ans5, b_ans5, a_ans6, b_ans6;
  printf("Test Complex Number Arithmetic");
  printf("\n");
  printf("Enter the first complex number in the form - real, imaginary - -->");
  scanf(" ( %lf , %lf )", &a1, &b1 );
  printf("\n");
  printf("Enter the second complex number in the form - real, imaginary - -->");
  scanf(" ( %lf , %lf )", &a2, &b2 );
  printf("\n");
  a_ans1 = (a1 + a2);
  b_ans1 = (b1 + b2);
  a_ans2 = (a1 - a2);
  b_ans2 = (b1 - b2);
  a_ans3 = (a1 * a2);
  b_ans3 = (b1 * b2);
  a_ans4 = (a1 / a2);
  b_ans4 = (b1 / b2);
  a_ans5 = sqrt (a1);
  b_ans5 = sqrt (b1);

  printf("Results:\n"
        "(%lf + %lf) (%lf + %lf) = (%lf), (%lf)\n"
        "(%lf + %lf) (%lf + %lf) = (%lf), (%lf)\n"
        "(%lf + %lf) (%lf + %lf) = (%lf), (%lf)\n"
        "(%lf + %lf) (%lf + %lf) = (%lf), (%lf)\n"
        "(%lf + %lf) (%lf + %lf) = (%lf), (%lf)\n",
        a1, b1, a2, b2, a_ans1, b_ans1
        a1, b1, a2, b2, a_ans2, b_ans2
        a1, b1, a2, b2, a_ans3, b_ans3
        a1, b1, a2, b2, a_ans4, b_ans4
        a1, b1, a2, b2, a_ans5, b_ans5);

return 0;

this is my updated code... i need it to read something like the below...
but i get a compiler error

assignment3.c: In function `main':
assignment3.c:33: error: syntax error before "a1"




Test Complex Number Arithmetic

Enter the first complex number in the form ( real, imaginary ) --> (1.0, 1.0)

Enter the second complex number in the form ( real, imaginary ) --> (2.1, 3.4)

Results:

(1.000000, 1.000000) + (2.100000, 3.400000) = ( 3.100000e+000, 4.400000e+000)
(1.000000, 1.000000) - (2.100000, 3.400000) = (-1.100000e+000, -2.400000e+000)
(1.000000, 1.000000) * (2.100000, 3.400000) = (-1.300000e+000, 5.500000e+000)
(1.000000, 1.000000) / (2.100000, 3.400000) = ( 3.443957e-001, -8.140263e-002)
abs(1.000000, 1.000000) = (1.414214)
abs(2.100000, 3.400000) = (3.996248)

Code:

printf("Results:\n"
        "(%lf + %lf) + (%lf + %lf) = (%lf, %lf)\n"
        "(%lf + %lf) - (%lf + %lf) = (%lf, %lf)\n"

Note the ',' on the end of each variable list staring a1, ...

a1, b1, a2, b2, a_ans1, b_ans1
a1, b1, a2, b2, a_ans2, b_ans2
a1, b1, a2, b2, a_ans3, b_ans3
a1, b1, a2, b2, a_ans4, b_ans4
a1, b1, a2, b2, a_ans5, b_ans5);

Add more commas
Each parameter needs a comma, even those at the end of a line

Edit: beaten

thanks. it helped alot.
