Programming In C Practical 18
Question 1
Write a program to check string is palindrome or not.
Palindrom.cpp
C
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
char str[30];
int i=0,j=0,flag=0;
printf("\nEnter a string: ");
scanf("%s",str);
while(str[i]!='\0')
{
i++;
}
i--;
while(j<=i)
{
if(str[j]!=str[i])
{
flag=1;
break;
}
j++;
i--;
}
if(flag==1)
printf("\nString is not palindrom");
else
printf("\nString is palindrom");
getch();
}
Output
Question 2
Write a program to demonstrate all string library functions.
Format.cpp
C
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
clrscr();
char str[50],str1[50],str2[50],str3[50],str4[50],str5[50],str6[50];
int len;
printf("\n-----------------String length----------------");
printf("\nEnter string:");
scanf("%s",str);
len=strlen(str);
printf("Length of string is: %d",len);
printf("\n\n-----------------String concatanation----------------");
printf("\nEnter string 1:");
scanf("%s",str1);
printf("\nEnter string 2:");
scanf("%s",str2);
strcat(str1,str2);
printf("Concat string is: %s",str1);
printf("\n\n-----------------String comparison-----------------");
printf("\nEnter string 1:");
scanf("%s",str3);
printf("\nEnter string 2:");
scanf("%s",str4);
if(strcmp(str3,str4)==0)
printf("Strings are same");
else
printf("Strings are not same");
printf("\n\n-----------------String copy----------------");
printf("\nEnter string:");
scanf("%s",str5);
strcpy(str6,str5);
printf("Copied string is: %s",str6);
getch();
}
Output
