    char string1[100] = "C programming", string2[] = " is high level language";

    int i, j;
    
    for (i = 0; string1[i] != '\0'; ++i)
    {
        printf("i = %d\n", i);
    }

    // concatenating characters 
    for (j = 0; s2[j] != '\0'; ++j, ++i)
    {
        s1[i] = s2[j];
    }
    

    string1[i] = '\0';
    printf("After concatenation: ");
    puts(string1);
    return 0;
}

Output:
