strchr() function
In C++, strchr() is a predefined function used for string handling. cstring is the header file required for string functions.

This function Returns a pointer to the last occurrence of a character in a string.
The character whose last occurrence we want to find in passed as the second argument to the function and the string in which we have to find the character is passed as the first argument to the function.

char *strrchr(const char *str, int c) 

Here, str is the string and c is the character to be located. It is passed as its int promotion, but it is internally converted back to char.
Given a string in C++, we need to find the last occurrence of a character, lets say ‘a’.


Input : string = 'This is a string'

Input :string = 'My name is Ayush'
Output :12

int main()
  char str[] = "This is a string";
  char * ch = strrchr(str,'a');
  cout << ch - str + 1;
