C++ Program to define a function and incorporate the array of structures to input and store any 30 records

C++ Program to define a function and incorporate the array of structures to input and store any 30 records

Display the following using functions incorporated through structure definition viz. display of all entered records,sort the records according to the marks in descending order and display of sorted records.



#include<iostream.h>

#include<conio.h>

#include<string.h>

#include<stdio.h>

struct ward

{

char name[20];

float marks;

} stud[5];

void display();

void sort();

void dispsort();

main()

{

clrscr();

// Data entry

clrscr();

cout<<"D A T A : ENTRY PROCESS: Enter 5 Records Initially"<<endl;

for(int i=0;i<5;i++)

{

cout<<"\nEnter name";

cin>>stud[i].name;

cout<<"\nEnter marks";

cin>>stud[i].marks;

}

       clrscr();

       display(); // Call of Function

       // to display data entered.

       cout<<"Press any key to continue";

       getch();

       clrscr();

       sort(); // Call of Function

// to sort data

       clrscr();

       cout<<"Press any key to display ";

       cout<<"the sorted data";

       getch();

       dispsort(); // Call of Function

// to display the sorted data.

       cout<<endl;

       cout<<"Press any key to continue";

C++ Program to Rotates a word

C++ Program to Rotates a word
This program prints all the rotation of a word.
Say if the input word is "space", then it prints
>>space
>>paces
>>acesp
>>cespa

>>espac

 #include <stdio.h>
#include <string.h>
#include <conio.h>
void main()
{
char w[50],buf[50],temp[50],buf2[10];
clrscr();
printf("Enter a word to see it's rotation :");
fflush(stdin);
gets(w);
strcpy(temp,w);
printf("All the rotation of the word \"%s\" are :",w);
for(int i=0;i<strlen(w);i++)
{
strcpy(buf,strnset(w,' ',i));
for(int j=0;j<i;j++)
buf2[j]=temp[j];
buf2[j]='\0';
strcat(buf,buf2);
//To straighten the output
gotoxy(strlen(w)-i,4+i);
puts(buf);
}
getch();
}
