Sample Solution:

C Code:

#include<stdio.h>
#define N 10

int main() {
    char str1[80], str2[80];
    int i;

    // Prompt for user input
    printf("Input a string: ");
    scanf("%s", str2);

    // Copy characters from str2 to str1
    for(i=0; str2[i]!='\0'; i++)
        str1[i]=str2[i];
    str1[i]='\0';

    // Output results
    printf("\n");
    printf("Original string: %s", str1);
    printf("\nNumber of characters = %d\n", i);

    return 0;
}
