我不斷收到此異常 - 發生異常。 EXC_BREAKPOINT（代碼=1，子代碼=0x1b8c50bb0）

Question

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

int main()
{
    char first[] = "This is the first part of";
    char second[] = "the full string, this being the second half\n.";
    char buffer[70];
    strcpy(buffer,first);
    strcat(buffer,second);
    puts(buffer);
    return 0;
}

我在 strcat function 上收到錯誤，請協助

Answer 1

似乎數組buffer的大小不足以包含連接的字符串。

聲明它至少像

char first[] = "This is the first part of";
char second[] = "the full string, this being the second half\n.";
char buffer[sizeof( first ) + sizeof( second ) - 1];
