float是什么意思 c语言main函数

使用 sizeof 操作符计算int, float, double 和 char四种变量字节大小 。
sizeof 是 C 语言的一种单目操作符,如C语言的其他操作符++、–等,它并不是函数 。
sizeof 操作符以字节形式给出了其操作数的存储大小 。
实例
#include
int main()
{
int integerType;
float floatType;
double doubleType;
char charType;
// sizeof 操作符用于计算变量的字节大小
printf(\”Size of int: %ld bytes\\n\”,sizeof(integerType));
printf(\”Size of float: %ld bytes\\n\”,sizeof(floatType));
printf(\”Size of double: %ld bytes\\n\”,sizeof(doubleType));
printf(\”Size of char: %ld byte\\n\”,sizeof(charType));
return 0;
}
运行结果:
Size of int: 4 bytes Size of float: 4 bytes Size of double: 8 bytes Size of char: 1 byte计算 long long, long double 字节大小
实例
#include
int main()
{
int a;
long b;
long long c;
double e;
long double f;
printf(\”Size of int = %ld bytes \\n\”, sizeof(a));
printf(\”Size of long = %ld bytes\\n\”, sizeof(b));
printf(\”Size of long long = %ld bytes\\n\”, sizeof(c));
printf(\”Size of double = %ld bytes\\n\”, sizeof(e));
printf(\”Size of long double = %ld bytes\\n\”, sizeof(f));
return 0;
}
运行结果:
Size of int = 4 bytesSize of long = 8 bytes Size of long long = 8 bytes Size of double = 8 bytes Size of long double = 16 bytes【float是什么意思 c语言main函数】本文来源于发迹号www.fajihao.com
