这是以下代码:当我尝试访问数组的第一个值时,为什么它会给出分段错误？这些警告是什么？
#include<stdio.h>
int main(void)
{
int *ptr = {1,2,3,4,5};//Is it not similar to char *ptr="Stackoverflow"?
printf("%d\n",*ptr);// why Segmentation fault(core dumped) instead of 1
return 0;
}
...
output:
warning: initialization makes pointer from integer without a cast [enabled by default]
int *ptr = {1,2,3,4,5};
