c++ - Run-Time Check Failure #2 - s for array of C-Strings -

i have following 2 2d arrays of c-strings. trying copy first 1 onto second using strcpy() function. however, keep getting runtime error.

#define _crt_secure_no_warnings  #include <cstring> #include <iostream>  using namespace std;  int main() {      char word1[3][3] = { "hello", "bonjour", "ni hao" };     char word2[3][3] = { "steve", "pei", "frank" };      char temp[] = "";      (int = 0; < 3; i++) {         strcpy(temp, word1[i]);         strcpy(word1[i], word2[i]);         strcpy(word2[i], temp);     }       (int = 0; < 3; i++) {         cout << word2[i] << " ";     }      cout << endl; } 

in code find several mistake.

• your char array word1,word2,temp isn't initialize properly.you need increase size of array.
• in loop use 3.it break output if word's length become grater 4.

so here give little solution.but better use user input size of array input can match properly.

#define _crt_secure_no_warnings  #include <cstring> #include <iostream>  using namespace std;  int main() {      char word1[10][10] = { "hello", "bonjour", "ni hao" };//increase array size fit word     char word2[10][10] = { "steve", "pei", "frank" };//same here      char temp[10] = "";//same here      (int = 0; < 10; i++) {         strcpy(temp, word1[i]);         strcpy(word1[i], word2[i]);         strcpy(word2[i], temp);     }       (int = 0; <10; i++) {         cout << word2[i] << " ";     }      cout << endl; }
