STRNCPY()

this function copies a specified number of characters from one string to another.

char *strncpy(char *destination, char *source, int n);

#include <stdio.h>
#include <string.h>

int main() {
    // Declare the source string
    char source[] = "Hello, C Programming!";
    
    // Declare a destination string with sufficient space
    char destination[20];
    
    // Use strncpy to copy 10 characters from source to destination
    strncpy(destination, source, 10);
    
    // Manually null-terminate the string, just in case
    destination[10] = '\0';
    
    // Print the result
    printf("Copied string: %s\n", destination);
    
    return 0;
}

 * OUTPUT:
    Copied string: Hello, C P


 * makes a copy of a maximum n characters taken from the string pointed to by 
   source and stores them in the location pointed to by destination
    -  if source contains fewer characters than n, all of them are copied. the 
       finishing null character is only added to the copied string if this character 
       is in n range

char *result = strncpy(destination, source, num);
 
 * result points to the destination string, with the first num characters of source 
   copied. If the source is shorter than num, the destination is padded with '\0'
