1、利用循环计算多个圆柱体积。
/*计算n个圆柱体体积*/ #include<stdio.h> int main(void) { double r,v,h; double cylinder(double r,double h); printf("Enter r and h:"); scanf("%lf%lf",&r,&h); v=cylinder(r,h); printf("v=%.3f\n",v); return 0; } double cylinder(double r,double h) { double result; result=3.1415926*r*r*h; return result; }
2、输出用电量并计算水费。
/*输出用电量并计算应付电费*/ #include<stdio.h> int main(void) { double x,y; printf("Enter x: "); scanf("%.2f",&x); if(x<=0) printf("输入结果错误，请重新输入"); else if(0<x<=50) y=0.53*x; else y=0.53*x+(x-50)*0.05; printf("y=%.2f\n",y); return 0; }
3、计算多个用户的电费。
/*计算多户人家的电费*/ #include<stdio.h> int main(void) { int i,n; double x,y; double fee(double x); printf("Enter n:"); scanf("%d",&n); for(i=1;i<=n;i++) { printf("Enter x:"); scanf("%2f",&x); if(x<=0) printf("输入错误，重新输入"); else{ y=fee(x); } printf("y=%.2f\n",y); } return 0; } double fee(double x) { double y; if(x<=50) { y=0.53*x; } else { y=0.53*x+0.05(x-50); } return y; }
