Write a program using for loops to produce a hollow box using the asterisk (*) symbol. The program should prompt the user for the height of the hollow box and check to see that the user entered a number greater than or equal to 3 and less than or equal to 40. If the user enters an invalid number, the program will print an error message and exit. If the user enters a valid number the program will print a hollow box of height and width n, where n is the number the user entered at the console.

我很乱

我是新手。。。。

谢谢

如果有人愿意帮我

麻烦

pm我

我给你我的msn。。。

#include <stdio.h>
int main()
{
int i,j,k;
printf("Enter a value:\n");
scanf("%d", &i,j,k);
{
for(i=0; i<=3; i++)
for(j=0; j>=40; j--)
printf(" ");
{
for(k=1; k<=i; k=k+1)
printf("*");
printf("\n");
}
}
}

看來基礎該好好提升, 還有如果不清楚該怎麼做的話, 先畫出 flow chart 才開始編寫

刚写好的，拿去参考吧 (不知道对不对)

代码：

#include <stdio.h>
int main(void) {
int iSize, iMin = 3, iMax = 40;
int i, j;
printf("Enter the size (Between %d ~ %d): ", iMin, iMax);
scanf("%d", &iSize);
if ((iSize >= iMin) && (iSize <= iMax))
{
for (i = 1; i <= iSize; i++)
{
for (j = 1; j <= iSize; j++)
{
if ((i == 1) || (i == iSize))
{
printf("*");
}
else if ((j == 1) || (j == iSize))
{
printf("*");
}
else
{
printf(" ");
}
}
printf("\n");
}
}
else
{
printf("Error: Invalid value entered!\n");
}
return 0;
}

复制代码
