C语言基础：计算多维数组的大小
#include <stdio.h>
int main(void)
{
int box[3][3];
float year_sales[52][5];
char pages[40][60][20];
printf("Bytes to hold int box[3][3] %d bytes\n", sizeof(box));
printf("Bytes to hold float year_sales[52][5] %d bytes\n",
sizeof(year_sales));
printf("Bytes to hold char pages[40][60][20] %ld bytes\n",
sizeof(pages));
return 1;
}
输出结果
Bytes to hold int box[3][3] 36 bytes Bytes to hold float year_sales[52][5] 1040 bytes Bytes to hold char pages[40][60][20] 48000 bytes
