【C】Data size

每種機器上面的data type size不一定一樣，與其聽別人說，不如自己驗證。

#include <stdio.h> #define BYTES 8 int main(void) {         printf("Get Data Type size...\n");         printf("int    %d\n", sizeof(int) * BYTES);         printf("float  %d\n", sizeof(float) * BYTES);         printf("double %d\n", sizeof(double) * BYTES);         printf("char   %d\n", sizeof(char) * BYTES);         printf("unsigned long %d\n", sizeof(unsigned long) * BYTES); #if 0         printf("  %d\n", sizeof() * BYTES); #endif         printf("short %d\n", sizeof(short) * BYTES);         printf("long  %d\n", sizeof(long) * BYTES);         return 0; }
