ispunct() Prototype
int ispunct(int ch);
The ispunct() function checks if ch is a punctuation character as classified by the current C locale. By default, the punctuation characters are !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~.
The behaviour of ispunct() is undefined if the value of ch is not representable as unsigned char or is not equal to EOF.
It is defined in <cctype> header file.
ispunct() Parameters
ch: The character to check.
ispunct() Return value
The ispunct() function returns non zero value if ch is a punctuation character, otherwise returns zero.
Example: How ispunct() function works
#include <cctype>
#include <iostream>
using namespace std;
int main()
{
char ch1 = '+';
char ch2 = 'r';
ispunct(ch1) ? cout << ch1 << " is a punctuation character" : cout << ch1 << " is not a punctuation character";
cout << endl;
ispunct(ch2) ? cout << ch2 << " is a punctuation character" : cout << ch2 << " is not a punctuation character";
return 0;
}
When you run the program, the output will be:
+ is a punctuation character r is not a punctuation character
