❶ c語言 輸入羅馬數字轉換成十進制的數字
#include <stdio.h>
static int map[26] = {0};
#define BUF_SIZE 81
#define N 24
int getNumber(char *s)
{
char *p = s;
int number = 0;
int value;
char c;
while(*p && (*p != '\n')){
value = map[*p];
c = *(p+1);
if((c == '\0') || (c == '\n') || (map[c] <= value)){
number += value;
}else{
number -= value;
}
p++;
}
return number;
}
int main()
{
int n;
int i;
char buf[BUF_SIZE];
int out[N];
map['I'] = 1;
map['V'] = 5;
map['X'] = 10;
map['L'] = 50;
map['C'] = 100;
map['D'] = 500;
map['M'] = 1000;
scanf("%d\n", &n);
if(n > N) return 1;
for(i = 0; i < n; i++){
fgets(buf, BUF_SIZE, stdin);
out[i] = getNumber(buf);
}
for(i = 0; i < n; i++){
printf("%d\n", out[i]);
}
return 0;
}
❷ c語言題目。。。急！！！
1.#include<stdio.h>
int main()
{
static char *a[][10]={"","I","II","III","IV","V","VI","VII","VIII","IX"
"","X","XX","XXX","XL","L","LX","LXX","LXXX","XCC",
"","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"
}; /*建立對照表*/
int n,t,i,m;
printf("Please enter number:");
scanf("%d",&n); /*輸入整數*/
printf("%d=",n);
for(m=0,i=1000;m<3;m++,i/=10)
{
t=(n%i)/(i/10); /*從高位向低位依次取各位的數字*/
printf("%s",a[2-m][t]); /*通過對照表翻譯輸出*/
}
printf("\n");
}
*運行結果
1. Please enter number:863
863=DCCCLXIII
2. Please enter number: 256
256=CCLVI
3. Please enter number:355
355=CCCLV
4. Please enter number:522
522=DXXII
5. Please enter number:15
15=XV
*思考題
輸入正整數N，產生對應的英文數字元串並輸出，例如：
1 ONE 2 TWO 3 THREE
10 TEN 11 ELEVEN
135 ONE HUNDRED THIRTY FIVE
❸ C語言，怎麼把十進制數轉化成羅馬數字啊
#include<stdio.h>
intmain()
{
staticchar*a[][10]={"","I","II","III","IV","V","VI","VII","VIII","IX",
"","X","XX","XXX","XL","L","LX","LXX","LXXX","XC",
"","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"
};/*建立對照表*/
intn,t,i,m;
printf("Pleaseenternumber:");
scanf("%d",&n);/*輸入整數*/
printf("%d=",n);
for(m=0,i=1000;m<3;m++,i/=10)
{
t=(n%i)/(i/10);/*從高位向低位依次取各位的數字*/
printf("%s",a[2-m][t]);/*通過對照表翻譯輸出*/
}
printf(" ");
}
❹ C語言將羅馬數字轉換成阿拉伯數字
主要是因為a裡面殘留了上次輸入的數據，你在while語句的最後加一句話：memset(a, 0, 100);就OK了
❺ C語言 十進制數轉換為羅馬數字的引深
這不就是判斷嗎，跟輸入字元轉換成字元串一樣的
❻ C語言，數字轉羅馬。。
初始化錯了，如下試試:
static char *a[3][10]={
{" ","I","II","III","IV","V","VI","VII","VIII","IX" },
{" ","X","XX","XXX","XL","L","LX","LXX","LXXX","XCC"},
{" ","C","CC","CCC","CD","D","DC","DCC","DCCC","CM"}
};
❼ 如何使用C語言實現羅馬數字轉換成整數，以及整數轉換成羅馬數字
#include<stdio.h>
#include<string.h>
voidmain(){charstr[20];
chard[10][20]={"I","II","III","IV","V","VI","VII","VIII","IX","X"};
inti,k;
scanf("%s",str);
for(i=0,k=0;i<10;i++)if(strcmp(str,d[i])==0){k=i+1;break;}
if(k>0)printf("%s==>%d ",str,k);
scanf("%d",&k);printf("%d==>%s ",k,d[k-1]);
}
❽ c語言里的羅馬數字怎麼弄
不明白你要做什麼！如果是要說輸入阿拉伯數字輸出羅馬數字的話可以用以下方法
#include
using
namespace
std;
void
fout(int
i)
{
switch(i)
{
case
1:
{
printf("I");
break;
}
case
2:
{
printf("II");
break;
}
case
3:
{
printf("III");
}
case
4:
{
printf("IV");
break;
}
case
5:
{
printf("V");
break;
}
case
6:
{
printf("VI");
break;
}
case
7:
{
printf("VII");
break;
}
case
8:
{
printf("VIII");
break;
}
case
9:
{
printf("IX");
break;
}
case
10:
{
printf("X");
break;
}
}
}
void
main()
{
int
i;
cin>>i;
fout(i);
}
配了一個main()函數試下；
這個fout函數只能轉換10以下的數。如果有需要的話也可以寫出可任意轉換的函數不過有點煩不寫了
