Insertion Into Array Using Dynamic Pointer

#include<iostream>using namespace std;main(){ int i,num1,pos,n; int *p=new int[10]; cout<<"Enter Size Of Array:"; cin>>n; cout<<"Enter NumberS:"; for(i=0;i<n;i++) cin>>p[i]; cout<<"Number To be Added:"; cin>>num1; cout<<"Address-:"; cin>>pos; for(i=n;i>=pos;i--) p[i+1]=p[i]; p[pos]=num1; for(i=0;i<n+1;i++) cout<<p[i]; }

Insertion In Array by Pointers C++ Program Exampe

#include<iostream>
using namespace std;
#include<conio.h>
 main()
{
int num[50],n, num1, i, pos,*p;
cout<<"Enter Array Size : ";
cin>>n;
cout<<"Enter Numbers : ";
for(i=0; i<n; i++)
cin>>num[i];
p=num;
cout<<"Enter Number to be inserted : ";
cin>>num1;
cout<<"Enter position :";
cin>>pos;
for(i=n; i>pos; i--)
{
*(p+i)=*(p+i-1);
}
*(p+pos)=num1;
for(i=0; i<n+1; i++)
{
cout<<*(p+i)<<" ";
}
getch();
}

Enumeration Example

#include<iostream>
using namespace std;
main()
{
enum{ jan=1,feb,m,a,ma,ju,jul,au,sep,oct,nov,december };//Enumeration Variables
cout<<december;
}/*If We do not Initialize the Value of Enum Then By default value is 0 ..Then Jan will start from 0 and print 11 for december month */

Addition Of String without using strcat() function in C++

#include<iostream>
#include<stdio.h>
#include<string.h>
using namespace std;
main()
{
char n[20],s[50];
int i,j=0,len;
gets(n);
gets(s);
len=strlen(n);
for(i=len;s[j]!='\0';i++)
{
n[i]=s[j];
j++;
}
puts(n);

}

String Replace in C++ Using String ()

#include<iostream>
#include<conio.h>
#include<string>
using namespace std;
int main()
{
    string x="highschool";
    string y="middle";
     x.replace(1,0,y);
     cout<<x;
}
