Question

We were asked to write a simple program in C language to solve the equation, ax+b=0, for x. If a is 0, print a warning message and exit. This is what I have so far, but it's not compiling. Please correct my program and make comments as to what is wrong.

#include <stdio.h>

int main()

{

float a, b, x;

printf("Enter a and b separated by a comma="); scanf("%f, %f", &a, &b);

if (a==0){ printf("You entered an invalid number. "); return 0;}

else x=-b/a;

printf("x= %f -b/a ", a, b,);

return 0;

}
