Programming C++

Write a program to concentrate two string without library function strcat .

#include<stdio.h>

#include<conio.h>

                                Main()

{             

                                Int len a=0,lenb=0, i;

                                Char a[50] , b[50];

                                Printf(“enter first string”);

                                Gets(a);

Printf(“enter second string”);

                                Gets(b);

                                /* finding string length of first string */

                                     For (i=0; a[i]!=’\0’ ; i++)

                                                Lena=lena+1;

                                /* finding string length of second string */

                                     For (i=0; b[i]!=’\0’ ; i++)

                                                Lenb=lenb+1;

                                /* string concatenate */

                                     For (i=0; i<lenb; i++)

                                     a[lena+i] = b[i];

                                printf(“in the concatenate string is %s”,a);

                                }

Write a program to check weather a string is palindrome or not without using library function.

#include<stdio.h>

#include<conio.h>

                Main ()

{

                Char st[40];

                Int len=0, i=0, flag=1;

                Printf(“enter a string”);

                Gets(st);

                For(i=0; st[i]! = ‘\0; i++)

                Len=len + 1;

                For (i=0; i<=len/2; i++)

                {

                If(st[i]! = st [len-1-i])

                {

                Flag =0

                Break:

                }

}

If (flag==1)

Printf(“the given string is palindrome”);

Else,

Printf(“the given string is not palindrome”);

}

Write a program to read 10 string & display.

#include<stdio.h>

#include<conio.h>

                Main ()

{

                Char a [10] [20];

                Int i;

                For (i=0; i<10; i++)

                {

                Printf(“in enter %d string”, i+1);

                Gets(a[i]);

                }

                /* display 10 string */

                For (i=0; i<10; i++);

                Printf(“in %s”, a[i]);

                Gets();
