在for循环中多次打印字符-Printingacharactermultipletimesinaforloop

Unless you need to use a for-loop, I think this would be better for many cases:

除非你需要使用for循环，否则我认为这对许多情况会更好：

printf("%.*s\n", 5, "aaaaaaaaaaaaaaaaaaaaaaaaa"); 

Which will print the first 5 letters of the string (which happens to be more than enough a's)

这将打印字符串的前5个字母（恰好足够了）

Put into a complete program:

投入完整的计划：

int main() {
    int i;
    for(i=0; i <10; ++i)
        printf("%.*s\n", i+1, "aaaaaaaaaaaaaaaaaaa");
    return 0;
}

Output:

输出：

a
aa
aaa
aaaa
aaaaa
aaaaaa
aaaaaaa
aaaaaaaa
aaaaaaaaa
aaaaaaaaaa
