Answer 1

#include<stdio.h>
void solve_equation(int a, int b)
{
if(a==0)
{
if(b!=0) //if(a==0 && b!=0)
{
printf("Sorry,the expression is meaningless！\n");
}
else //if(a==0 && b==0)
printf("the root of the equation is any value~\n");
}
else
{
if(b==0)//if(a!=0 && b==0)
{
printf("the root of the equation is:x = 0 \n");
}
else //if(a!=0 && b!=0)
{
printf("the root of the equation is:x = %f \n", -b/(float)a);
}
}
}
int main()
{
int a;
int b;

printf("Please enter a and b(both of a and b are )\n");
scanf("%d%d", &a, &b);
printf("The equation as：%dx + %d = 0\n", a, b);

solve_equation(a, b);
return 0;
