Exercise 9

Write a C program to find the length of the given string.

SOURCE CODE:

/*Program to find length of given string.*/

#include<stdio.h>

#include<string.h>

void main()

{

 char str[30];

 int i,len=0;

 clrscr();

 printf("Enter string1:\n");

 gets(str);

 for(i=0;str[i]!='\0';i++)

  len++;

 printf("Length of given string is %d",len);

}

OUTPUT:

Write a C program to check whether the given string is palindrome or not.

SOURCE CODE:

/*Program to find whether a given string is palindrome or not.*/

#include<stdio.h>

#include<conio.h>

void main()

{

 char str[30];

 int i,j,len=0,flag=0;

 clrscr();

 printf("Enter string1:\n");

 gets(str);

 for(i=0;str[i]!='\0';i++)

  len++;

 for(i=len-1,j=0;i>=j;i--,j++)

 {

  if(str[i]!=str[j])

  {

   flag=1;

   break;

  }

 }

 if(flag==1)

  printf("\nString is not palindrome.");

 else

  printf("\nString is palindrome.");

}

OUTPUT:
