简介
模拟银行的钱数大写输出例如
345
叁肆伍
方法/步骤
首先打开VC++
文件》》》新建
创建一个C++空白文档
先声明头文件
复制代码 代码如下:
#include
声明变量
复制代码 代码如下:
char *p[10]={"零","一","二","三","四","五","六","七","八","九"};
由于用到了自定义函数，所以先声明
复制代码 代码如下:
void PrintInterger(char a[], int len);
void PrintDecimal(char a[],int len);
函数1，用于输出整数部分，主要是用switch case进行匹配转换
复制代码 代码如下:
void PrintInterger(char a[], int len)
{
int i, j, tag1, tag2, tag3;
tag1=(a[len-6]=='0' && a[len-7]=='0' && a[len-8]=='0');
tag2=(a[len-14]=='0' && a[len-15]=='0' && a[len-16]=='0');
tag3=(a[len-22]=='0' && a[len-23]=='0' && a[len-24]=='0');
printf("您的钱数是：n");
for(i=0,j=len; i
{
if(a[i] == '0' && i != len-1)
{
if((j == 5 && tag1) || (j == 13 && tag2) || (j == 21 && tag3 ))
;
else if((j == 21 && ! tag3 )||(j == 5 && ! tag1)||(j == 13 && ! tag2))
printf("万");
else if(j == 9 || j == 17 )
printf("亿");
else if(a[i+1] == '0' && i != len-1)
;
else if(a[i+1] != '0' && i != len-1)
printf("零");
else
;
}
else if(a[i] == '0' && i == len-1)
;
else if(a[i] != '0')
{
switch(a[i])
{
case '1': printf("%s",p[1]); break;
case '2': printf("%s",p[2]); break;
case '3': printf("%s",p[3]); break;
case '4': printf("%s",p[4]); break;
case '5': printf("%s",p[5]); break;
case '6': printf("%s",p[6]); break;
case '7': printf("%s",p[7]); break;
case '8': printf("%s",p[8]); break;
case '9': printf("%s",p[9]); break;
default: printf("error"); ; break;
}
switch(j)
{
case 2:
case 6:
case 10:
case 14:
case 18:
case 22: printf("%s","十"); break;
case 3:
case 7:
case 11:
case 15:
case 19:
case 23: printf("%s","百"); break;
case 4:
case 8:
case 12:
case 16:
case 20:
case 24: printf("%s","千"); break;
case 5:
case 13:
case 21: printf("%s","万"); break;
case 9:
case 17: printf("%s","亿"); break;
default: printf("%s",""); break;
}
}
}
printf("%s","圆");
}
函数2，用于输出小数部分，主要是用switch case进行匹配转换
复制代码 代码如下:
void PrintDecimal(char a[],int len)
{
int i;
for(i=0; i
{
switch(a[i])
{
case '0': printf("%s",p[0]); break;
case '1': printf("%s",p[1]); break;
case '2': printf("%s",p[2]); break;
case '3': printf("%s",p[3]); break;
case '4': printf("%s",p[4]); break;
case '5': printf("%s",p[5]); break;
case '6': printf("%s",p[6]); break;
case '7': printf("%s",p[7]); break;
case '8': printf("%s",p[8]); break;
case '9': printf("%s",p[9]); break;
default: printf("%s",p[0]); ; break;
}
switch(i)
{
case 0: printf("%s","角"); break;
case 1: printf("%s","分"); break;
case 2: printf("%s","厘"); break;
case 3: printf("%s","毫"); break;
default:; break;
}
}
}
主函数，变量的作用我说明了
复制代码 代码如下:
int main(void)
{
char Number[128];
char Interger[64], Decimal[64];
int lenI,lenD;
int i,j;
puts("*************************************");
puts("* This is a print program *");
puts("* used in a bank *");
puts("*************************************");
puts("please input the money:");
gets(Number);
i=0;j=0;
while((Number[i]!= '/0') && (Number[i]!= '.' )&& (Number[i] >= '0') && (Number[i] <= '9'))
{
Interger[i]=Number[i];
i++;
}
lenI = i;
if(Number[i]== '.')
{
i++;
while(Number[i]!= '/0' && Number[i] >= '0' && Number[i] <= '9')
{
Decimal[j++]=Number[i++];
}
if((j >= 4 )&& (Decimal[4] > '5'))
{
Decimal[3]+=1;
Decimal[4] = '/0';
}
}
if(j >= 4)
lenD = 4;
else
lenD = j;
PrintInterger(Interger, lenI);
PrintDecimal(Decimal,lenD);
printf("n");
return 0;
}
运行结果
