圆球的体积?看看我的程序对吗?C语言的知道了圆球的半径,求体积#define PI 3.14159#includevoid main(){ double r,s;printf("Piease input r:");scanf("%f",&r);s=(4/3)*PI*r*r*r;printf("s=%f",s);}

圆球的体积?看看我的程序对吗?C语言的
知道了圆球的半径,求体积
#define PI 3.14159
#include
void main()
{ double r,s;
printf("Piease input r:");
scanf("%f",&r);
s=(4/3)*PI*r*r*r;
printf("s=%f",s);
}

Answer 1

#define PI 3.14159
#include
void main()
{ double r,s; //将此处的double改成float型
printf("Piease input r:");
scanf("%f",&r);
s=(4/3)*PI*r*r*r; //将此处4/3改写成4.0/3.0
printf("s=%f",s);
}
