dd再答：thanks
是x,另外函数参数一定要指定类型,可以没有名字
对,他们只是一个变量的名字,至于这个名字叫a,b,c,...都无所谓,主要看在你的方法或类中是否有引用这个变量的地方,如若有也随之更换掉.
#include <math.h>void root(float a, float b, float c,
#includevoidsum_diff(floatop1,floatop2,float*psum,float*pdiff){*psum=op1+op2;*pdiff=op1-op2;}voidmai
#includeintmain(){intn;scanf("%d",&n);do{printf("%d",n%10);}while(n/=10);printf("\n");return0;}
doublen,max,min,sum,average;inti;sum=0.0;average=0.0;cin>>n;max=n;min=n;sum+=n;for(i=1;i>n;sum+=n;if
#includevoidmain(){inta,b,c,d;scanf("%d",&a);b=a/100;c=(a%100)/10;d=a%10;printf("%d",100*d+10*c+b);}
可以用sprintf(str,"%d",num);将数字输出为字符串,再用strlen(str)检查其长度：intnulen(intnum){charstr[10];sprintf(str,"%d",
#includemain(){intn;printf("Pleaseenteranumber:");scanf("%d",&n);if(n%2==0)printf("Thenumber%dis偶数\n
#includeintmain(void){longi;printf("请输入要判断的数\n");scanf("%ld",&i);if(i%2==0){printf("您输入的%ld是偶数\n",i)
defb():list1=[]while1:a=input()ifa=='.':breaklist1.append(eval(a))avg=sum(list1)/len(list1)returnavg
