I have been rattling my brain but have not been able to solve this.

删除的任何单个字符或操作员的从上面code和程序应打印 - 20倍

Delete any single character or operator from above code and the program should print "-" 20 times

请帮帮忙！

推荐答案

我不认为你可以通过的删除字符做，但我有三个解决方案，替换（当然，其中一人增加了一个角色，但只是因为你在你的程序中没有空格。如果你有空格，它会取代一个空格）。

I don't think you can do it by deleting a character, but I have three solutions that replace (well, one of them adds a character, but only because you have no whitespace in your program. If you had whitespace, it would replace a space).

解决方案1 ​​

int i,n=20;
for(i=0;-i<n;i--) // -i < n 
    printf("-");

解决方案2

int i,n=20;
for(i=0;i<n;n--) // n-- 
    printf("-");

解决方案3

int i,n=20;
for(i=0;i+n;i--) // while i + n is not zero 
    printf("-");
