help with program

Can someone help me with what I'm doing wrong. I'm getting "parse error before else" on the 19, 25, and 31 line.
Here is the assignment:Write a C program that takes as input three integers and then outputs them in sorted (ascending) order. Save your program in a file called p1.c. You don't have to handle the case with invalid inputs.

Code:

#include <stdio.h>
int main(void)
{
 int a, b, c, first, second, max;
 printf("Enter Number 1: \n");
 scanf("%d", &a);
 printf("Enter Number 2: \n");
 scanf("%d", &b);
 printf("Enter Number 3: \n");
 scanf("%d", &c);

 if ( a > b && a > c ) max=a;
 else if ( b > a && b > c ) max=b;
 else if ( c > a && c > b ) max=c;
 
 if ( max=a ) 
 {
  if ( b > c ) first= c; second= b;
  else first= b; second= c;
 }

 if ( max=b )
 {
  if ( a > c ) first= c; second= a;
  else first= a; second= c;
 } 
 
 if ( max=c )
 {
  if ( a > b ) first= b; second= a;
  else first= a; second= b;
 }

 printf("%d\n", first);
 printf("%d\n", second);
 printf("%d", max);

 return 0;

}

change Line 19 from

Code:

else first= b; second= c;

to

Code:

else{first= b; second= c;}

same for the other two errors

I fixed those and now when I compile I get like 20 errors. Am I defining things wrong?

Code:

if ( max==a )

== tests for equality, = is assignment.

Post your latest code, with braces in all the places you've missed them so far.
