I a Beginner in C++ ;

I will be thankful for you .

------------------------
first program : I need the user to enter his/her ful name and then the program separate the string to first name , middle name and the last name which stord in three different strings .
I do it like this ....
#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>
main()
{
int i=1,j,d=0,k,tmp,x;
char word[10],f[10],m[10],l[10];

cout<<"Enter Your Full Name\n";

while(cin>>word){
cout.width('\0');
cout<<"\n";
if(word!='\0'){
strcpy(f,word);
cout<<"\n Your First Name is.... \n";
cout<<f; }
strcpy(m,word);
cout<<"\n Your Middle Name is.... \n";
cout<<m;
strcpy(l,word);
cout<<"\n Your Last Name is.... \n";
cout<<l;
}
cout<<"\n";
getch();
return 0;
}

************************************************** **
second program: it ask the user to enter three word and then arranges the word in alphabetical order using string function to solve this.
I do it like this ....

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>
main()
{
int i=1,j,d=0;
char word[10],word1[10],word2[10];

cout<<"Enter How many time you want to do this .... \n";
cin>>j;
for(i=1;i<=j;i++){
cout<<"\nEnter First Word\n";
cin>>word;
cout<<"Enter Second Word\n";
cin>>word1;
cout<<"Enter Third Word\n";
cin>>word2;

cout<<"\nGiven word is arrenged in alphabetical order\n";
if(strcmp(word2,word1)&& strcmp(word2,word) ) {
cout <<word2;
cout<<"\n\n"; }
if(strcmp(word1,word)&& strcmp(word1,word2)){
cout <<word1;
cout<<"\n\n";}
if(strcmp(word,word2)&& strcmp(word,word1)){
cout<<word;}
cout<<"\n";
cout<<"\t\t ****************** \n"; }
getch();
return 0;
}

*******************************************
Third program: it Suppose to solve this summation series :
1+2 - 3+4 - 5+6 ...... N
I do it like this

#include <stdio.h>
#include <conio.h>
#define N 3

main()
{
int i,j,d=0,s=0; float sum = 0;
for (i=0; i <= N; i++){
sum +=((d-N)-(((d+i)+1)+((s+i)+2));
d=2+i;
s=2+i;
}
printf("%d: %4.6f\n", i, sum);
getch();
}

************************************************** *
Fourth program : it ask the user to entered two word and exchange the first half a part from word the first string with the second half a part from word the second string also exchange the second half a part from first string with with the first half a part string from the second .

I do it like this

#include<iostream.h>
#include<conio.h>
#include<string.h>
main()
{ int i,j;

cout<<"Enter How many time you want to do this a word";
cin>>j;
for(i=1;i<=j;i++) {
cout<<"\nEnter The Words\n";
char word1[6],word2[6],tmp[5],tmp1[5];
cin>>word1;
cin>>word2;
cout<<"\nThe first word is ";
cout<<word1;
cout<<"\nThe second word is ";
cout<<word2;
cout<<" \n\n";
strcpy(tmp1,word2);
strncpy(word2,word1,3);
cout<<"\n";
cout<<word2;
strcpy(tmp,word2);
strncpy(word1,tmp1,3);
cout<<"\n";
cout<<" \n\n";
cout<<word1;
cout<<" \n\n"; }
getch();
}

**************************************************
Fifth program: it Suppose to Generate 9 number and then 0,5
Example( a program Generate 055341122 it will be like this 0505341122 or like this 0555341122

I do it like this

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
main()
{
int i,j,d=0,k,tmp;
cin>>j;
while(d<j){
for(i=1;i<=9;i++){
k=1+rand()%6;
cout<<k;}
tmp=k;
cout<<tmp;
cout<<"\n";
d++;
}
getch();
