【NOI OpenJudge】【1.2】编程基础之变量定义、赋值及转换

01: 整型数据类型存储空间大小

#include<cstdio>
int main(){
	int a; short b;
	printf("%d %d",sizeof(a),sizeof(b));
	return 0;
}

02: 浮点型数据类型存储空间大小

#include<cstdio>
int main(){
	float a; double b;
	printf("%d %d",sizeof(a),sizeof(b));
	return 0;
}

03:其他基本数据类型存储空间大小

#include<cstdio>
int main(){
	bool a; char b;
	printf("%d %d",sizeof(a),sizeof(b));
	return 0;
}

04:填空：类型转换1

#include<cstdio>
int main(){
	printf("D C");
	return 0;
}

05:填空：类型转换2

#include<cstdio>
int main(){
	printf("F E");
	return 0;
}

06:浮点数向零舍入

#include<cstdio>
int main(){
	float a;
	scanf("%f",&a);
	printf("%d",(int)a);
	return 0;
}

07: 打印ASCII码

#include<cstdio>
int main(){
	char c;
	scanf("%c",&c);
	printf("%d",(int)c);
	return 0;
}

08:打印字符

#include<cstdio>
int main(){
	int a;
	scanf("%d",&a);
	printf("%c",a);
	return 0;
}

09:整型与布尔型的转换

#include<cstdio>
int main(){
	int a;
	scanf("%d",&a);
	bool b = a;
	printf("%d",b);
	return 0;
}

10:Hello, World!的大小

#include<cstdio>
int main(){
	char s[] = "Hello, World!";
	printf("%d",sizeof(s));
	return 0;
}
