在这个示例中,我们定义了一个谓词函数is_uppercase,用于检查字符是否为大写字母。然后,我们使用std::find_if在字符串str中查找第一个大写字母。如果找到了大写字母,我们将输出该字母;否则,我们将输出一条消息,指示未找到大写字母。 std::find_if可以与std::string一起使用,以搜索满足特定条件的字符。然而...

For example, converting a string to uppercase takes one of the following forms: inti,length=strlen(myString);for(i=0;i<length;i++){myString[i]=toupper(myString[i]);} or std::transform(myString.begin(),myString.end(),myString.begin(),(int(*)(int))std::toupper); ...

There is no alternative that I am aware of. However, it is very simple to create a function that does this. If you would like to make a string lowercase in C++. You can use this code. You can just add 32 to the ascii value of a lower case letter to get an uppercase letter. ...
