Question

我需要在右侧以垂直方向排列一列正确的星号。根据输入的长度，右侧的星号是关闭的。

#include <stdio.h>
#include <string.h>
#define CHECKHEADER1 "************************************************************\n"
#define CHECKHEADER2 "*                                                          *\n"
#define MAX 2

typedef char STR30[30+1];
typedef char STR302[30+1];
typedef struct EmployeeRecord
{
    STR30 FullName;
    STR302 GoodFullName;

} EmployeeRecord;

void CheckPrinter();
void PrintCheckHeadings(EmployeeRecord name[]);
void PrintCheckStub();

int CheckNumber = 100;
FILE * cfgfile;

int main(void)
{
    int i;
    EmployeeRecord name[MAX];
    for ( i = 0; i < MAX; i++)
    {
    printf("enter username: ");
    scanf("%s",name[i].FullName);
    }
    //name[1].FullName = "Sam Smithh";
    //EmployerData = fopen("EmployerData.txt", "r");
    cfgfile = fopen("strings.txt", "r");
    if (cfgfile==NULL) printf("can't open file\n");
    //CheckPrinter();
        printf("%-1s%6s%s", "*",name[0].FullName,"*\n");
    PrintCheckHeadings(name);
}
/*
void CheckPrinter()
{
    PrintCheckHeadings();
}
*/
void PrintCheckHeadings(EmployeeRecord name[])
{
    //printf(CHECKHEADER1);
    //printf(CHECKHEADER2);
    //printf("%-1s%37s%5i%17s", "*","Check Number", CheckNumber,"*");
     int i=0, j=0,x=0;
      int maxline = 60;
       char cfgstring[16][60];
         for(x=0; x<MAX; x++) printf("%s%25s\n",cfgstring[j],"*");
{

 while (fgets(cfgstring[i], maxline, cfgfile)) {      // while not EOF
    cfgstring[i][strlen(cfgstring[i])-1] = '\0';      // remove CR from line
    i++;
   }

    printf(CHECKHEADER1);
    printf(CHECKHEADER2);
    printf("%-1s%37s%5s%18s", "*","Check Number ", cfgstring[1],"*\n");
    printf("%-1s%5s%41s","*  ", cfgstring[2],"*\n");
    printf("%-1s%5s%35s","*  ", cfgstring[3],"*\n");
    printf("%-1s%5s%31s","*  ", cfgstring[4],"*\n");
    printf(CHECKHEADER2);
    printf(CHECKHEADER2);
    printf("*  Pay to the order of                                     *\n");
    printf(CHECKHEADER2);
    printf("%-1s%6s%s", "*",name[x].FullName,"*\n");
    printf(CHECKHEADER2);
    printf("%-1s%15s","*","Sum in words\n");
    printf(CHECKHEADER2);
    printf(CHECKHEADER2);
    printf("%-1s%18s","*","Reference Number\n");
    printf(CHECKHEADER2);
    printf(CHECKHEADER2);
    printf(CHECKHEADER1);
}
 fclose(cfgfile);
}
void PrintCheckStub()
{


}

这就是我的样子：这就是它需要的样子：

请指出我正确的方向，我需要学习如何做到这一点，所以我不希望它完全为我完成。 strcpy + strcat是正确的方法吗？

看起来很棒！

printf("*  %-25s%7s%11.2f%10s%9.2f *\n",MyAssociate[i].FullName,"Reg Pay",MyAssociate[i].Payrate,"Fed Tax",MyAssociate[i].FedTax);
printf("*  %-25s%7s%11.2f%12s%7.2f *\n",cfgstring[3],"OVT Pay",MyAssociate[i].OVT,"State Tax",MyAssociate[i].StateTax);
printf("*  %-25s%7s%9.2f%10s%9.2f *\n","New Corio, New Mexico","Gross Pay",MyAssociate[i].Gross,"SSI Tax",MyAssociate[i].SsiTax);
printf("*  %-25s%7s%11.2f%12s%7.2f *\n","65790","Net Pay",MyAssociate[i].NetPay,"Tax Total",TOTtax);

输出：

Answer 1

您可以使用以下模板“左对齐”任何内容：

printf("*  %-56s*\n", "foo");

示例：

//         0         1         2         3         4         5         6
//         0123456789012345678901234567890123456789012345678901234567890123456789
   printf("*  Pay to the order of                                     *\n");

   printf("*  %-56s*\n", "");
   printf("*  %-56s*\n", name[x].FullName);
   printf("*  %-56s*\n", "");
   printf("*  %-56s*\n", "Sum in words");
   printf("*  %-56s*\n", "");

如果要将内容进一步向右移动，请根据需要调整前缀空格数和格式字符串%-56s。

注意：printf()确实会返回与sprintf()非常相似的字符数。

示例输出：

*  Pay to the order of                                     *
*                                                          *
*  Foo B Bar                                               *
*                                                          *
*  Sum in words                                            *
*                                                          *
*  Reference Number                                        *

Answer 2

以下代码：

清理控制逻辑
删除了不必要的杂乱
可能应该将#define MAX_CFG_STR_LEN从60
清理EmployeeRecord结构的定义
只有第1行... 4（第0行未使用）所以为什么cfgstring[][]数组定义为16行？
我没有弄乱右手*的对齐，所以需要'调整'
添加了适当的错误检查
将打印头行显示修改为易于调整的功能
您可以将所有固定内容行放入表中，然后只需调用printf()并输出所需的表条目，而不是函数：printCheckHeader1()和printCheckHeader2()。建议将该表作为`static const table [] = {...};
从cfgfile的每个输入中删除尾随换行符，同时处理多字符换行符，并且不修剪任何有效字符

这不是完成的代码，但确实解决了OP发布的代码中最糟糕的问题
