I wrote this function that's supposed to do StringPadRight("Hello", 10, "0") -> "Hello00000".
char *StringPadRight(char *string, int padded_len, char *pad) {
int len = (int) strlen(string);
if (len >= padded_len) {
return string;
}
int i;
for (i = 0; i < padded_len - len; i++) {
strcat(string, pad);
}
return string;
}
它有效，但有一些奇怪的副作用...其他一些变量会发生变化.我该怎么解决这个问题？
