c语言输入两个实数x,y,判断点(x,y)在哪个象限或哪条坐标轴上

#includemain(){floata,b,c;scanf("%f%f",&a,&b);c=a+b;printf("%.2f\n",c);}

#includevoidmain(){\x09floata,b,y;\x09printf("inputab:\n");\x09scanf("%f%f",&a,&b);\x09if(a>b)\x09\x

不用画流程图吧,直接写代码#includevoidmain(){floatx,y,z,temp;printf("pleaseinputx,y,z:");scanf("%f,%f,%f",&x,&y,&

#includemain(){intn,i,j;scanf("%d",&n);n=2*n-1;for(i=1;i2*i){for(j=1;j

是输入结束不会还是取整数小数不会?再问：都不会，完全没有思路，只有寻求帮助了再答：������֪��˼·����ֱ��Ҫ����再问：ֱ��Ҫ����ϣ������C++��д��˳��˵������

#include#includemain(){floatx,y;while(1){printf("请输入x=");scanf("%f",&x);if(x>=-5&&x

#includeintmain(){inta,b;floatc;printf("请输入两个整数和一个实数\n");scanf("%d%d%f",&a,&b,&c);c=a+b+c;printf("这三

#include#include#defineE2.7182voidmain(void){floatx;floaty;scanf("%d",&x);if(x>=-1)y=pow(x,2)+1;

.你计算机专业的话,C不懂你以后怎么活!建议以后还是好好看看,真的不难,特别不难,给你个if-else参考,其他的照搬差不多：#includevoidmain(){floatx,y;print("pl

packageex3001;importjava.util.Scanner;publicclassEx3001{publicstaticvoidmain(String[]args){doublex,y

并不复杂,考察运算符优先级.!z代表z求非；当z=0的时候,!z=1；当z!=0的时候,!z=0这句话,也就是当y大于1的时候等效于x+1；y

#include#includeintmain(){floata,x,y;scanf("%f%f",&a,&x);y=pow(a,5)+sin(a*x)+log(a+x)+pow(2.718,a*x)

浮点数如果比较是否相等的话,一般是通过(fabs(a-b)b,a

#includeintmain(){inta,b,k;scanf("%d%d",&a,&b);if(a

#include#includevoidconv(char*s){inti;for(i=strlen(s)-1;i>=0;i--)putchar(s[i]);printf("\n");}in
