C Beautifier

[DeFault]

I would to attempt a simple code beautifier but I would like to know the right way to start this.

The process I would like to attempt is:
1. Start count out at zero.
2. Read in lines of original.c one by one.
3. For each line:
4. Remove all the white space (tabs and spaces) from the front of the line.
5. If the first non-white character of the line is ‘}’ decrease count by one.
6. Insert at the front of each line count*2 number of space characters.
7. If the first non-white character of the line is ‘{’ increase count by one.

The code I wrote is a not a good attempt so I would appreciate any help in fixing this code

int main(char string[])
{
const char sp = '.';
const char cr = '*';
const char tab = '$';
const char rb = '{';
const char br = '}';
const char space = ' ';
 
 
char ch;
 
int in = 0;
int count = 0;
 
int inSpace = 0;
 
while( (ch = string[count]) == sp|| ch == cr|| ch == tab || ch == space )
count++;
 
 
while ( ch = string[count++] )
{
 if (ch == br)
 {
   count--; 
 }
 
}
 
while ( ch = string[count++] )
{
      if ( ch = rb)
      {
           count++;
      }    
}
 
}
