文字列を格納する配列

C



#include <stdio.h>



int main(int argc, char* argv[])

{

    char str1[4];
    str1[0] = 'A';

    str1[1] = 'B';

    str1[2] = 'C';

    str1[3] = '\0';
    printf("str1 = %s\n", str1);
    char str2[] = {'A', 'B', 'C', '\0'};

    printf("str2 = %s\n", str2);
    char str3[] = "ABC";

    printf("str3 = %s\n", str3);
    char str4[4];

/*  str4 = {'A', 'B', 'C', '\0'};   エラー！    */

/*  str4 = "ABC";                   エラー！    */
    return 0;
