输出逆序数

int main()
{int x , b0, b1 , b2 , y;scanf("%d",&x);x = (int)fabs(x);b2 = x / 100;b1 = (x-b2*100)/10;b0 = x % 10;printf("%dn%dn%dn",b2,b1,b0);y = b0*100 + b1*10 +b2;printf("%dn",y);return 0;
}

计算年利率

#include <math.h>main(){float a, b, c, disc, p, q;scanf("%f%f%f",&a,&b,&c);disc = b*b - 4*a*c;p = -b / (2*a);q = sqrt(disc)/(2*a);printf("%7.4f,%7.4fn",p+q,p-q);}

计算球的体积和表面积

#include <math.h>
const double pi = 3.14159;main(){double  r, surface,volume;scanf("%lf",&r);surface = 4 * pi * pow(r,2);volume = 4.0/3.0 * pi * pow(r,3);printf("%lfn%l
