Q6) How does a CGI program handle the following string?
f=John&f=Doe
A6) The strategy is that every data has a field name(f) followed by =, its value, and a separator (&) before the next field’s name. The program has to skip two characters to get to the value of the first input and, after that, three characters must be skipped between values. Here the program chops of the “f=” and “&f=” from “f=John&f=Doe “ and the final display is John Doe  

Q7) Is this statement correct for a CGI program?
cout<<"Content type:text/html\n";
A7) the correrct form should be as : cout<<"Content-type: text/html\n\n";  the codes is missing a “-“ and one more“\n”.

Q8) What does the following statement do?
for(i=2;str[i]!='&';i++){
     fname[n]=str[i];
     n++;}
fname[n++]=0;
A8) This code in CGI expresses that every data has a field(f) name followed by =, its value, and a separator (&) before the next field’s name. The program has to skip two characters(“f=”) to get to the value of the first input (and stops as it gets to “&”)and, after that, three characters(“&f=”) must be skipped between values. 
Generally speaking this CGI program is to take in two strings and display them .The result of the code will be Just the first name(whatever it is).
