1. C语言题目 函数题目
#include int isprime(int n){ int i; if(n<2) return 0; for(i=2;i*i<=n;++i) if(n%i==0) return 0; return 1;}int main(void){ int n; scanf("%d",&n); if(isprime(n)) puts("yes"); else puts("no"); return 0;}
2. C语言题目。函数。
#include "stdio.h"
double fun0(double a)
{
a=12*a;
return(a);
}
double fun1(double b)
{
b=2.54*b;
return(b);
}
double fun2(double c)
{
c=0.01*c;
return(c);}
void main()
{
int n,x,y,z;
printf("将英尺转换英寸,输入0;将英寸转换为厘米,输入1;将厘米转换为米,输入2:\n");
scanf("%d",&n);
switch (n){
case 0:
printf("输入英尺：");
scanf("%f",&x);
fun0(x);
printf("结果是%f",x);
break;
case 1:
printf("输入英寸：");
scanf("%f",&y);
fun1(y);
printf("结果是%f",y);
break;
case 2:
printf("输入厘米：");
scanf("%f",&z);
fun2(z);
printf("结果是%f",z);
break;
default:
printf("error");
break;
}
}
