To find the character in a string in Python: Use the find() method to find the index of the first occurrence of the supplied character in the input String. Use an if statement to check if the returned index is not -1; if so, print that index; otherwise, print an error. Use find(...
Method 6 – Using Combined Functions in Excel to Find Last Occurrence of Character in String We’re going to use the SEARCH function, the RIGHT function, the SUBSTITUTE, the LEN, the CHAR functions to show the string after the last occurrence of a character, so we’ll output the department...

cout<< st2.find(str1,2) << endl;//6 从st2的位置2(b)开始匹配,返回第一次成功匹配时匹配的串(abc)的首字符在st2中的位置,失败返回npos//测试size_type find (const charT* s, size_type pos = 0) const;cout << st2.find("abc",2) << endl;//6 同上,只不过参数不是string而是char*//...

string::find( char c, size_type pos = 0 ) returns the index of the first occurrence of c in the string beginning at index pos. string::substr( size_type pos = 0, size_type n = npos ) returns the substring of n characters beginning from, and including, the character at index 'pos...
right({stringfield},len({stringfield})-4) Former Member 2014 May 09 0 Kudos Hi Matt, Sometimes there are more than 4 charaters in front of the number. At times there are just numbers without the NDC, or details preceeding the number which could be a note of what took place ...
