printf("char type length=%d/n",sizeof(char));
printf("short type length=%d/n",sizeof(short));
printf("long type length=%d/n",sizeof(long));
printf("double type length=%d/n",sizeof(double)); } 输出结果如下：
下面输出DSP 数据类型的长度 int type length=4 float type length=4 char type length=1 short type length=2 long type length=8 double type length=8 ////////////////////////////////// windows 平台的结果
int type length=4
float type length=4
char type length=1
short type length=2
long type length=4
double type length=8
_int64 type length=8
Press any key to continue 在windows 平台里边存在一种很特殊的类型 long long 和_int64 8个字节
