#include void main() { int i=1,sum=0; while(i<100) { sum=sum+i; i++; } printf(\} 2．

#include void main() { int score,max,min,i=0; float sum=0.0,average; printf(\请输入学生的成绩:\\n\ scanf(\ max=min=score; while(score!=-1) { if(score>=0&&score<=100) { sum=sum+score; i++; if(maxscore) min=score; } scanf(\ } average=sum*1.0/i; printf(\ printf(\有效成绩共%d个学生，平均分为：%f\\n\} 3．

#include void main() { int a,b,c; int count=0; int m=100; printf(\的水仙花数为：\ do {

a=m/100; b=(m-100*a)/10; c=m; if(a*a*a+b*b*b+c*c*c==m) { printf(\ count++; } m++; } while(m<1000); printf(\的水仙花数共%d个\\n\} 4．

#include #define N 20 void main() { int i; float m=1.0,n=2.0,t,p; double sum=0.0; t=m/n; for(i=1;i<=N;i++) { sum=sum+t; p=m+n; m=n; n=p; t=m/n; } printf(\前20项的结果为：%lf\\n\} 5．

#include #include void main() { int m,i=2; int flag=1; printf(\请输入一个数，验证是否为质数：\ scanf(\ for(i=2;i<=sqrt(m);i++) if (m%i==0) { flag=0; break;

}

}

if(flag=1) printf(\恭喜，你输入的数%d是质数！\\n\else printf(\对不起，你输入的数%d不是质数！\\n\
