In C ++, STRRCHR () is a predefined function for string manipulation. Cstring is the header file required for string functions.
This function returns a pointer to the last occurrence of a character in the string.
The last character we want to find to occur is passed as the second argument to the function, and we must find the string of that character to pass as the first argument to the function.
syntactic
Char * STRRCHR (const char * STR, int c)
In this case, STR is the string and c is the character to be located. It is passed as an int promotion, but internally converted back to char.
using
Given a string in C ++, we need to look for the last occurrence of the character, let’s say “a”.
Example:
Input: string =’ This is a string ‘output: 9
Input: string =’ my name is Ayush’ output: 12
algorithm
1. Pass the given string in the STRCHR () function and mention the character you need to point to.
2. The function returns a value and prints the value.
Example 1:
Output: 9
Example 2:
Output:
String after last e is : eks
String after last m is : (null)
Practical use: Since it returns the entire string after the last occurrence of a particular character, it can be used to extract the suffix of a string. For example, when we know the first number, know the entire leading zeros in a denomination. This example is shown below.
Output:
The original string is: 10000000
The denomination value is: 10000000
