003.基本数据类型与赋值

数据类型

整形

• 短整形-short-2Bytes(16bits)
  • short a = 1;
• 整形-int-4Bytes (32bits)
  • int a = 6;
• 长整形-long-8Bytes(64bits)
  • long a = 10;

浮点形

• 单精度型-float-4Bytes(32bits)
  • float a = 4.5f;
• 双精度型-double-8Bytes(64bits)
  • double a = 4.5;

字符类型

• 单个字符类型-1Bytes(8bits)
  • char c = “a”;
  • char c = 97;
  • printf (“%c”,c);
• 字符串
  • string str = “ABCDEF”;

• cpp
