String Examples

1) Length of string

#include<iostream.h>
#include<conio.h>
void main()
{
    int len=0;
    char s[10];
    clrscr();
    cout<<"\n Enter the string: ";
    cin>>s;
    while(s[len]!='\0')
    {
        len++;
    }
    cout<<" Length = "<<len;
getch();
}

Here is the output :)))

2) Swaping two strings

#include <iostream.h>
#include <conio.h>
#include <string.h>
#include <malloc.h>

int main()
{
   char first[100], second[100], *temp;
   clrscr();

   cout<<"Enter the first string: ";
   cin>>first;

   cout<<"Enter the second string: ";
   cin>>second;

   cout<<"\nBefore Swapping\n";
   cout<<"\nFirst string: "<<first;
   cout<<"\nSecond string: "<<second;

   temp = (char*)malloc(100);

   strcpy(temp,first);
   strcpy(first,second);
   strcpy(second,temp);

   cout<<"\n\nAfter Swapping\n";
   cout<<"\nFirst string: "<<first;
   cout<<"\nSecond string: "<<second;

   getch();
}

Here is the output :)))

3) Reverse String

#include<iostream.h>
#include<string.h>
#include<conio.h>
void main()
{
    char arr[100];
    clrscr();

    cout<<"\n Enter a string to reverse :\n ";
    cin>>arr;

    strrev(arr);

    cout<<"\n Reverse of entered string is :\n "<<arr;
    getch();
}

Here is the output :)))
