My instructor at my engineering institute has given the following assignment question: Create a database of scientists and labourers and maintain the same by making use of inheritance. We haven't been taught the database connectivity with program execution, so that's not to be used. I wrote the following code: [code] …

Could someone please why do we say that the syntax of enhanced for loop (for-each) in java in streamlined. Also, my java compiler does not compile programs containing the enhanced for loop. It gives errors like: for(int x:collection) { } ^ ; expected Could someone suggest solutions to this?

I am not able to understand why in the following program it is mentioned in my book: The value of ~a is ANDed with 0x0f (0000 1111) in binary in order to reduce its value to less than 16, so it can be printed by use of the binary array. …

Could someone please tell me how to overload ++ operator in the postfix form. ++ sholud increment the instance variable avar of following class: class A { int avar; public: A() { avar=0; } A(int a) { avar=a; } void display() { cout<<endl<<avar; }

I copied your code and executed it: count =0 in the output. You have used return 0 in your prime() method, so the if in main never receives value 1 and count is never incremented.

Your question syas that the function must have a integer parameter representing the number of days past from 1/1/1990. where's that in your code so far??? Your function is still accepting three parameters for the date 1/1/1990. I think it should like this: void yrCalc(int &day,int &month,int &year,int days_past) where …

In your program# 1,after computing sum and product and displaying them to th user , what's the use of cin >> sum >> product; This is again demanding that you enter two more values for sum and product. Also , in your program # 2 , cin.getline is used to …

C++ tries to make user-defined data type much the same way as the built in data type. We use different kind of operators with the bulit in data type . What about using those operators with the user defined data types, eg classes. Thats where operator overloading comes in.It is …

I am not able to figure out the code required for accepting a string from user , but the memory for it should be dynamically allocated and referenced using pointer. Have a look at the following: char *p=new char[length_of_string+1]; This statement would work to dynamically allocate the string ,but still …

scanf always uses the syntax: scanf("<format_specifier>",&<name_of_variable>); You used the & operator.

Here's one possible way to get desired string2: [code=cplusplus] #include<iostream.h> #include<string.h> int main() { int len1; char *p,*q; cout<<"enter string 1 length : "; cin>>len1; p=new char[len1+1]; cout<<endl<<"enter string 1:"; cin>>p; //--------------------------------- q=new char[len1+1]; cout<<endl<<"enter string 2:"; cin>>q; cout<<endl<<strlen(q); //--------------------------------- int l=strlen(q); for(int i=0;i<l;i++); for(;*(p+i)!='\0';i++) { *(q+i)=*(q+(i-4)); } *(q+i)='\0'; cout<<endl<<"result …

One possible solution to your if block is: if( !(strcmp(chartryname,charname)) && !(strcmp(chartrypassword,charpassword) ) cout<<"All entries are correct"; /* Result at execution if entries are correct : if( !(0) && !(0) ) => if ( 1 && 1) => true */
