1#include#includevoid main(){printf("%g\n",fabs(-6)+16

2#include#includemain(){int a,b ;printf("Input a,b:\n");scanf("%d%d",&a,&b); if (a>b) printf("%g\n",sqrt(a)); else printf("%g\n",sqrt(b));}2

3#include main() { float a; printf("Input a:\n");scanf("%g",&a); printf("the square of a=%g\ta cubed=%g\n",a*a,a*a*a); }2

4#include main() { float a,b,c,d,sum; printf("Input a,b,c,d:\n");scanf("%f%f%f%f",&a,&b,&c,&d); sum=a+b+c+d; printf("%f\n",sum/4); }2

5#include main(){int n,a,b,c,d,e,s;printf("请输入一个五位数：\n");scanf("%d",&n);a=n%10;b=n/10%10;c=n/100%10;d=n/1000%10;e=n/10000;s=a+b+c+d+e;printf("%d\n",s);}3

2#includemain(){float r,C,S;printf("Input r :\n");scanf("%f",&r);C=2*3

14159*r;S=3
