我的任务是编写一个对字符串进行排序的程序（不使用指针，因为我们还没有学过这些）。但我被困住了，我需要一点帮助。这是我到目前为止所拥有的：
#include <stdio.h>
int main()
{
printf("Enter text to be sorted alphabetically:\n");
char a[100][100]; // This is my array of text.
// It has a maximum of 100 words, each with 100 characters.
int i = 0;
while(scanf("%c", a[i][100]) != EOF)
{
i++; // This is where I get the string from the user.
// I think this is where the problem is.
}
int l, x, j, m = 0;
char k[100]; // This is the swap variable for the bubble sort.
for(l = 0; l < i; l++)
{
for(j = 0; l < i - l; j++)
{
if(a[j][m] > a[j+1][m])
{
for(x = 0; x < 100; x++)
{
k[m] = a[j][m]; // Bubble sort.
a[j][m] = a[j+1][m];
a[j+1][m] = k[m];
}
m = 0; // m is set back to 0.
}
if(a[j][m] == a[j+1][m])
{
m++; // m is supposed to represent the mth letter.
// so if the first two letters are equal, it increases m.
j--;
}
}
}
printf("Sorted text is: /n");
for(l = 0; l < i; l++)
{
for(j = 0; j < 100; j++)
{
printf("%s", a[l][j]); // Print out the final result.
// I think I messed up this one too.
}
printf("\n");
}
}
此代码拒绝编译。它说：
format ‘%c’ expects argument of type ‘char *’, but argument 2 has type ‘int’
有人可以告诉我我做错了什么吗？谢谢。
