🍩BC43 及格分数

题目:

代码实现:

#include int main() {int score;while(scanf("%d",&score)!=EOF) //多组输入，直到没有输入值就停止{if(score>=60){printf("Pass\n");}else {printf("Fail\n");}}    
}

🦀BC44 判断整数奇偶性

题目:

代码实现:

#include int main() {int num1 =0;while(scanf("%d",&num1)!=EOF){if(num1%2==0){		  //一个数%2==0就是偶数printf("Even\n");}else if(num1%2==1){printf("Odd\n");	//一个数%2==1就是奇数}}
}

🫒BC45 最高分数

题目:

答案:

#include int main() {int a,b,c;int max = 0;scanf("%d %d %d",&a,&b,&c);max = (a>b)?((a>c)?a:c):((b>c)?b:c); printf("%d",max);![在这里插入图片描述](https://img-blog.csdnimg.cn/7943bfd584584e0083d56cb429daec4c.png)return 0;
}

🍥BC46 判断是元音还是辅音

题目:

答案:

#include int main() {char input;while(scanf("%c",&input)!=EOF){if(input=='\n')		//遇到\n需要过滤掉{continue;}if(input=='a'||input=='A'||input=='e'||input=='E'||input=='i'||input=='I'||input=='o'||input=='O'||input=='u'||input=='U'){printf("Vowel\n");}else {printf("Consonant\n");}}
}

🍙BC47 判断是不是字母

题目:

答案:

#include int main() {char input;while(scanf("%c",&input)!=EOF){if(input=='\n'){continue;}if((input>=65&&input<=90)||(input>=97&&input<=122))//字符底层用ascii码存储，大写字母ascii码范围是65-90，小写字母是97-122{printf("%c is an alphabet.\n",input);}else {printf("%c is not an alphabet.\n",input);}}
}

🌰BC48 字母大小写转换

题目:

答案:

#include int main() {char ch;while(scanf("%c",&ch)!=EOF){if(ch>=65&&ch<=90){printf("%c\n",ch+32);	//大写字母+32就是小写字母 参考上面ascii码表}if(ch>=97&&ch<=122){printf("%c\n",ch-32);	//小写字母-32就是大写字母}}
}

🍜BC49 判断两个数的大小关系

题目:

答案:

#include int main() {int num1=0;int num2=0;while(scanf("%d %d",&num1,&num2)!=EOF){	//多组输入直到停止输入为止 oj系统会帮助你停止if(num1>num2){printf("%d>%d\n",num1,num2);}else if(num1printf("%d<%d\n",num1,num2);}else{printf("%d=%d\n",num1,num2);}}
}

🍿BC50 计算单位阶跃函数

题目:

答案:

#include int main() {int t;while(scanf("%d",&t)!=EOF){if(t>0){printf("1\n");}else if(t==0){printf("0.5\n");}else{printf("0\n");}}    
}

🍆BC51 三角形判断

题目:

答案:

#include int main() {int a = 0, b = 0, c = 0;while(~scanf("%d %d %d",&a, &b,&c)){if(a==b&&b==c){printf("Equilateral triangle!\n");}else if((a==b||a==c||b==c)&&(a+b>c && a+c>b && b+c>a)){printf("Isosceles triangle!\n");}else if( a+b>c && a+c>b && b+c>a){printf("Ordinary triangle!\n");}else {printf("Not a triangle!\n");}}
}

🫓BC52 衡量人体胖瘦程度

题目:

答案:

#include int main() {int weight,height;while(scanf("%d %d",&weight,&height)!=EOF){float bmi = weight*1.0/(height*height/10000.0);if(bmi<18.5){printf("Underweight\n");}else if(bmi>=18.5&&bmi<=23.9){printf("Normal\n");}else if(bmi>23.9&&bmi<=27.9){printf("Overweight\n");}else{printf("Obese\n");}}
}
