| + | * C++ string append()新增文本 | ||
| + | * 使用append()加入文字常用方法: | ||
| + | * 直接添加另一個完整的字串: | ||
| + | * 如str1.append(str2); | ||
| + | * 新增另一個字串的某一段子字串: | ||
| + | * 如str1.append(str2, 11, 7); | ||
| + | * 添加幾個相同的字元: | ||
| + | * 如str1.append(5, '.'); | ||
| + | * 注意,個數在前字符在後.上面的代碼意思為在str1後面添加5個".". | ||
| + | * <sxh c++> | ||
