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

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

#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char name[20];
int l,f,i;
clrscr();
printf("enter the string");
gets(name);
l=strlen(name);
for(i=0;i<l;i++)
{
if(name[i]!=name[l-1])
{
f=0;
break;
}
else
{
f=1;
l--;
}
}
if(f==1)
{
printf("no is palindrome");
}
else
{
printf("no is not palindrome");
}
getch();
}

C program to accept n numbers store all perfect numbers in an array and display this array.

Write a ‘C’ program to accept ‘n’ numbers, store all perfect numbers in an array and display this array.

#include<stdio.h>
#include<conio.h>
void main()
{
int a[30],i,j,k,n,m,sum,l=0;
clrscr();
printf("enter the range value");
scanf("%d",&n);
for(i=0;i<n;i++)
{
printf("enter no");
scanf("%d",&m);
j=1;
sum=0;
while(j<m)
{
k=m%j;
if(k==0)
{
sum=sum+j;
}
j++;
}
if(sum==m)
{
a[l]=m;
l++;
}
}
for(i=0;i<l;i++)
{
printf("%d",a[i]);
}
getch();
}
