1. Usingstring::rfind The standard approach to find the index of the last occurrence of a char in a string is using thestring::rfindmember function. If the character doesn’t occur in the string, the function returnsstring::npos.

Alternatively, you can usefindto compare specific character ranges in two strings. To do this, you should pass the starting position and length of the range as arguments to thefindmethod: #include<iostream>#include<string>using std::cin;using std::cout;using std::endl using std::string;using...

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...
cout << "\nThe ASCII value of the entered character is : " << (int)c << "\n\n"; return 0; } Output: We hope that this post helped you develop a better understanding of the concept of finding the type-casting in determining the ASCII value of the character, in C++. For any ...
