How to read specifically formatted data from a file?

Question

I\'m supposed to read inputs and arguments from a file similar to this format:

Add  id:324  name:\"john\" name2:\"doe\" num1:2009 num2:5 num2:20

Answer 1

perhaps this is what you want ?

#include 
#include 

int main()
{
char str[200];
FILE *fp;

fp = fopen("test.txt", "r");
while(fscanf(fp, "%s", str) == 1)
  {
    char* where = strchr( str, ':');
    if(where != NULL )
    {
      printf(" ':' found at postion %d in string %s\n", where-str+1, str); 
    }else
    {
      printf("COMMAND : %s\n", str); 
    }
  }      
fclose(fp);
return 0;
}

If output of it will be

COMMAND : Add
 ':' found at postion 3 in string id:324
 ':' found at postion 5 in string name:"john"
 ':' found at postion 6 in string name2:"doe"
 ':' found at postion 5 in string num1:2009
 ':' found at postion 5 in string num2:5
 ':' found at postion 5 in string num2:20
