C :

#include <stdio.h>
#include <string.h>
int main()
{
 int k,n,i,m;
 char a[300],b[300],ch;
 scanf("%d",&n);
		 scanf("%c",&ch);
		 if(ch==13)
			 printf("\n");
 gets(a);

 
 scanf("%d",&m);
 for(k=0,i=m-1;i<n;i++)
	b[k++]=a[i];
 b[k]='\0';
 puts(b);


 return 0;
}

C++ :

#include <stdio.h>
#include <string.h>
#define N 80
void fun(char a[N],int m)
{char *p1,b[N];int i,l;
p1=a;i=1;l=0;
while(i<m){i++;p1++;}
while(*p1!='\0')
{b[l]=*p1;
 p1++;
 l++;
}
b[l]='\0';
puts(b);
}
int main()
{char a[N];int m,n;
scanf("%d\n",&n);
gets(a);
scanf("%d",&m);
fun(a,m);
return 0;
}

Java :

import java.util.Scanner;

public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner input = new Scanner(System.in);
		int n = input.nextInt();
		String s = input.next();
		int m = input.nextInt();
		for(int i = m-1; i < n; i ++){
			System.out.print(s.charAt(i));
		}
		
	}

}

Python :

n = input()
stri = raw_input()
m = input()
arr = list(stri)
cot = ""
for i in range(m-1,n):
    cot +=  arr[i]
print cot
