Here is my code to find substring entered by the user in the given string. bool find_str(char *str, char const *substr) { while(*str) { if(*str++ == *substr) { char const *a = substr; while((*str++ == *++a)); /*empty*/ if(*a == '\0') return true; } } return ...
要截取一个字符串的后面两位,我们需要先计算出字符串的长度,然后使用substring方法来截取。下面是一个示例代码: publicclassSubstringExample{publicstaticvoidmain(String[]args){Stringstr="Hello World";intlength=str.length();Stringresult=str.substring(length-2);System.out.println("截取后面两位:"+result);}}...

substring方法是String类中的一个方法,它用于截取字符串中的一部分。它有两种重载形式: substring(int beginIndex):从指定索引位置开始截取到字符串的末尾。 substring(int beginIndex, int endIndex):从指定索引位置开始截取到指定索引位置之前的字符。 其中,beginIndex表示截取的起始位置(包括该位置的字符),endIndex表示...

In this program, we will learn how to check whether a substring is present in a string or not without using library function?We are implementing a function named myStrStr() this function will return 1 if substring present in the string and return 0, if substring is not present in the ...

方法一:使用substring方法 Java提供了一个名为substring的方法,可用于截取字符串的子串。该方法接受两个参数,即截取的起始位置和结束位置(不包括结束位置)。我们可以利用这个方法来截取指定字符之前的内容。 下面是一个示例代码: Stringstr="Hello World";intindex=str.indexOf(" ");// 查找空格的位置Stringresult=...
