实测代码

 1 void CalculateDataTypeSize(void)
 2 {
 3     printf("sizeof(char}      = %u
", sizeof(char));
 4     printf("sizeof(short}     = %u
", sizeof(short));
 5     printf("sizeof(int}       = %u
", sizeof(int));
 6     printf("sizeof(long}      = %u
", sizeof(long));
 7     printf("sizeof(long long} = %u
", sizeof(long long));
 8     printf("sizeof(float}     = %u
", sizeof(float));
 9     printf("sizeof(double}    = %u
", sizeof(double));
10 }

输出结果
