/ *我正在尝试使用＆＃39; toupper＆＃39;函数使随机生成的句子中的第一个单词成为大写。我想我在句子[0]和句子[1] * /

之间放了一个printf函数

                            sentence [1], 
                            sentence [2],
                            sentence [3],
                            sentence [4],
                            sentence [5]);
                        }

由于它们是不变的，因此您无法将其用于字符串的问题。您将需要使用一些可写存储来获得结果。如果你不想，你可以只用大写第一个单词的第一个字符，然后用printf中的第二个字符开始写第一个单词：

printf( "%c%s %s %s %s %s %s. \n",
                            toupper(sentence[0][0]), 
                            &sentence[0][1], 
                            sentence[1],
                            ..........

使用toupper功能
