how do I use strlen and strcpy (can't use strncpy) to split string in this function

void split_string(char *str, char *string_1, char *string_2)

-------------------

#include #include

void split_string(char *str, char *string_1, char *string_2) { int len = strlen(str) / 2; strcpy(string_1, str); strcpy(string_2, str); }

int main() { char str[100]; fgets(str, 100, stdin); int lenth = (strlen(str) - 1) / 2; char str1[lenth], str2[lenth];

split_string(str, str1, str2);

printf("%s", str1); printf("%s", str2); return 0; }
