Copy the third through fifth elements of a seven-element array into a three-element array - C Array

Description

Copy the third through fifth elements of a seven-element array into a three-element array

Demo Code

#include <stdio.h>  
#define LEN1 7   //w w  w  . j  a  v a 2s.  co  m
#define LEN2 3  
  
void copy_arr(int ar1[], const int ar2[], int n);  
void show_arr(const int [], int);  
  
int main(void){  
    int orig[LEN1] = {1,2,3,4,5,6,7};  
    int copy[LEN2];  
      
    show_arr(orig, LEN1);  
    copy_arr(copy, orig + 2, LEN2);  
    show_arr(copy, LEN2);  
          
    return 0;  
}
void copy_arr(int ar1[], const int ar2[], int n) {  
    int i;  
    for (i = 0; i < n; i++)  
        ar1[i] = ar2[i];  
}  
  
void show_arr(const int ar[], int n){  
    int i;

    for (i = 0; i < n; i++)  
        printf("%d ", ar[i]);  
    putchar('\n');  
}
