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

int main(void) 
{
    char arr1[100];
    char arr2[100];
    char arr3[100];
    // arr1 선언
    strcpy(arr1, "hello, i am array");
    printf("%s\n", arr1);
    // arr2 선언
    strcpy(arr2, "This is following text");
    printf("%s\n", arr2);
    // arr1 = arr1 + arr2
    strcat(arr1, arr2);
    printf("%s\n", arr1);
}



//////////결과값//////////////
hello, i am array
This is following text
hello, i am arrayThis is following text
