Title: Difference Between C and C++ Language


Name:
abhi
Question:  most of the c program is also a c++ program . is it necessory that it should produce the same result in running in both languages ? if yes ,why.if no give  

               an example?

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Answer:

As well as i understand both of the languages have the syntax difference and the concept of the program is the same in both languages. C++, as the name suggests is a superset of C.As a matter of fact, C++ can run most of C code while C cannot run C++ code.C supports procedural programming while C++ supports both procedural and object Oriented programming language. One main difference is that C++ supports operating overloading and C doe's not.

Hope this would Help...

Title: Structures in C++ Language


Name:
machano
Qiuestion:





The CandyBar structure contains three members. The first member holds the brand name of a candy bar. The second member holds the weight (which may have a fractional part) of the candy bar, and the third member holds the number of calories (an integer value) in the candy bar. Write a program that declares such a structure and creates a CandyBar variable called snack, initializing its members to “Mocha Munch”, 2.3, and 350, respectively. The initialization should be part of the declaration for snack. Finally, the program should display the contents of the snack variable.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Answer:

You didn't mentioned the Language, I am posting it in C++ Language.

#include<iostream.h>
#include<conio.h>
struct CandyBar
{
    char Brand_Name[50];
    float Brand_Weight;
    int Brand_Calories;

};

void main()
{
    CandyBar snake={"Mocha Munch",2.3,350};
    cout<<"\nBrand Name     :"<<snake.Brand_Name;
    cout<<"\nBrand Weight   :"<<snake.Brand_Weight;
    cout<<"\nBrand Calories :"<<snake.Brand_Calories;
    cout<<"\n";
    getche();
}

Title: Challenge

 

Name:
machano
Qiuestion:





Write a program that asks the user to enter his or her first name and then last name, and that then constructs, stores, and displays a third string, consisting of the user’s last name followed by a comma, a space, and first name. Use char arrays and functions from the cstring header file. A sample run could look like this: Enter your first name: Flip Enter your last name: Fleming Here’s the information in a single string: Fleming, Flip.

Answer:

You didn't mentioned the Language, I am posting it in C++ Language.

#include <iostream>
#include <cstring>
#include <conio.h>

int main()
{
   char first_name[100],last_name[100],full_name[100];
   cout << "Please enter your first Name : \n";
   cin.getline(first_name,40);
   cout << "Please enter your second name: \n";
   cin.getline(last_name,40);
    strcat(full_name,last_name);
   strcat(full_name,", ");
   strcat(full_name,first_name);
   cout << "Your Full Name is:" << full_name<< "\n";
   getche();
   return 0;
}

Title: Arrays in C++

Qiuestion:





Write a program that asks the user to enter up to 10 golf scores, which are to be stored in an array. You should provide a means for the user to terminate input prior to entering 10 scores. The program should display all the scores on one line and report the average score. Handle input, display, and the average calculation with three separate arrayprocessing functions.

 

Answer:



#include <iostream>
#include <cstring>
#include <conio.h>

int main()
{
   int golf_scores[10]={-1,-1,-1,-1,-1,-1,-1,-1,-1,-1},sum=0,count=0;
   char ch;
   float avg;

   for(int i=0;i<10;i++)
   {
        cout<<"\nEnter the golf Scores at the "<<i<<" location in array other than -1:";
      cin>>golf_scores[i];
      while(golf_scores[i]==-1)
      {
          cout<<"\n -1 is not allowed please reenter:";
         cin>>golf_scores[i];
      }


      sum=sum+golf_scores[i];
      count+=1;
      cout<<"\nAre you want to enter more Numbers (y/n) :";
      cin>>ch;
      if(ch=='n' || ch=='N')
          break;
   }


   avg=(float)sum/count;
   cout<<"\nYour Golf Scores are given below\n";
   for(int i=0;i<10;i++)
   {
       if(golf_scores[i]!=-1)
       cout<<golf_scores[i]<<"     ";

   }
   cout<<"\n Average Scores:"<<avg;
   getche();
   return 0;
}

  Title: Searching in Character Arrays using strstr function in C++ Language

 

Name:
Sobijo
Qiuestion:





Write a program that inputs a line of text and a search string from the keyboard. Using function strstr, locate the first occurrence of the search string in the line of text, and assign the location to variable searchPtr of type char *. If the search string is found, print the reminder of the line of text beginning with the search string. Then use strstr again to locate the next occurrence of the search string in the line of text. If a second occurrence is found, print the reminder of the line of text beginning with the second occurrence. {Hint: the second call to strstr should contain the expression searchPtr + 1 as its first argument.}

Answer:



#include<iostream.h>
#include<conio.h>
#include<cstring>
void main()
{
    char line[500];
    char search[100];
    char* searchPtr=NULL;
    cout<<"\nEnter The Line of text :";
    cin.getline(line,500);
    cout<<"\nEnter The Seacrh String:";
    cin.getline(search,100);
    int check=0;
    while(check==0)
    {
        if(searchPtr==NULL)
        {
            searchPtr=strstr(line,search);
            if(searchPtr==NULL)
            {
                cout<<"\n No search found ...";
                check=1;
            }
            else
                cout<<searchPtr<<"\n\n";

        }
        else
        {
            searchPtr=strstr(searchPtr+1,search);
            if(searchPtr==NULL)
            {
                cout<<"\n No More search found ...";
