编写程序判断所输入的字符是英语字母,数字符号,特殊符号

修改如下：#include"stdio.h"int_isalpha(chara){if((a>=65&&a=97&&a

///c语言的,#inlcudevoidmain(){inta;printf("pleaseinputanumber:\n");scanf("%d",&a);if(a%5）printf("thisnu

voidmain(){inta;scanf("%d",&a);if(a%2==0){printf("偶数");}else{printf("奇数");}}programJO;vara:integer;b

#includeintmain(){inta,b;printf("请输入两个整数,以空格隔开（形如12）：\n",a,b);scanf("%d%d",&a,&b);if(b!=0&&a!=0&&a%b

非要限制输入的大小么?过会儿给你发个#include#includevoidmain(){charm_input;intdigit=0,space=0,others=0,uppercase=0,low

#include#includevoidmain(){printf("请数输入一个字符：");charch=getchar();if(ch>='a'&&ch='A'&&ch='0'&&ch

#includemain(){intt;intis(intt);printf("输入年份为");scanf("%d\n",&t);t=is(t);if(t=1)printf("%d是闰年",t);el

#includedoubletriangle(doublea,doubleb,doublec){if(a+b>c&&b+c>a&&a+c>b)return1;elsereturn0;}doublede

C语言?#include"stdio.h"intmain(){intnum,i=0;printf("请输入一个数字\n");scanf("%d",&num);while(num){\x05++i;\x

是VB吗再问：恩再答：X=inputbox（“输入”）iffix（x）=xthenifx/2=0thenprintx+“为偶数”elseprintx+“为奇数”endifendif再答：X=input

main(){intn;printf("pleaseinputanumber\n");scanf("d%",&n);if(n%2==0)printf("thenumberisoushu");elsep

#includeintmain(){chara,b;a=getchar();scanf("%c",&b);printf("a=%c\n",a);printf("b=%c\n",b);return0;}

#include#includeusingnamespacestd;intchild(intn)//如果是素数则返回原数n,否则返回一个因子{if(n>n;if(n

#include#includeintmain(void){intn,sum=0,count=0,s;printf("输入一个整数:");scanf("%d",&n);while(n){s

intiIsRunAround(intnNum){intnCount=0;//位数intnStep=0;intnCur=nNum;intarrNumber[10];//各位数,个位到最高位intarr

INPUTxa=xMOD2IFa=0THENPRINT"x是偶数"ELSEPRINT"x是奇数"ENDIFEND

    tmp = InputBox("随便输入几个数,用逗号隔开就可以了.")   &n

importjava.io.*;/***输入整数n,输出由n行n列星号字符组成的三角形图案**@authoruser**/publicclassXing2{publicstaticvoidmain(S

这三道题我已经上机试过了,正确!1.clearaccept"请输入任意一个字符："toxdocasecasex>="A"andx="a"andx=48andasc(x)

使用什么VB的话是INPUTNIFN\2=0THENPRINT'是'ELSEPRINT'否'ENDIFEND
