strchr() prototype
const char* strchr( const char* str, int ch ); char* strchr( char* str, int ch );
The strchr()
function takes two arguments: str and ch. It searches for the character ch in the string pointed to by str.
It is defined in <cstring> header file.
strchr() Parameters
ptr
: Pointer to the null terminated string to be searched for.ch
: Character to search for.
strchr() Return value
If the character is found, the strchr()
function returns a pointer to the location of the character in str, otherwise returns null pointer.
Example: How strchr() function works
#include <cstring>
#include <iostream>
using namespace std;
int main()
{
char str[] = "Programming is easy.";
char ch = 'r';
if (strchr(str, ch))
cout << ch << " is present \"" << str << "\"";
else
cout << ch << " is not present \"" << str << "\"";
return 0;
}
When you run the program, the output will be:
r is present "Programming is easy."
