这段代码那里错了?
#include "stdafx.h"#include<stdio.h>
int main(void)
{
int n, m;
n = 30;
while(++n <= 33)
printf("%d",n);
n = 30;
do
printf("%dl",n);
while(++n <= 33);
printf("\n***\n");
for(n = 1; n*n < 200; n += 4)
printf("%d", n);
printf("%d\n", n);
printf("\n***\n");
for(n = 2; m = 6; n < m; n *= 2, m+=2)
printf("%d %d\n", n, m);
printf("\n***\n");
for(n = 5; n > 0;n--)
{
for(m = 0; m <= n; m++)
printf("=")
}
getchar();
return 0;
}
