    Finding a String in a file

    Hi,
    How can i find a string in a file?

    Code:
    int search(*emp_id)
    {
    	int flag=0,len;
    	len=strlen(*emp_id);
    	rewind(fp);
    	while(fp!=EOF)
    	{
    		if(*fp==*emp_id)
    		{
    			flag=1;
    			fp++;
    			emp_id++;
    			continue;
    		}
    		else
    		{
    			flag=0;
    			fp++;
    			continue;
    		}
    	}
    }
    I have attempted this function but with no luck. I know why it doesnt work but i am unable to solve this problem.

    Also i would like to know how can i change color of the text to be displayed on the screen and how to keep the text flashing on the screen.

    Specify platform

    In DOS you can use textcolor(number + BLINK); defined in conio.h
    number is an integer representing a 4 bit color.

    strstr can be used for searching a string within another string. Cannot be used to find a string in a file.
