Thread: strstr() question

hi, i was implementing strstr() to see how it works.

Code:

#include<iostream>
using namespace std;

int main()
{
char str[] = "this is a test";
char*s;
s=strstr(str,"test");
cout<<s<<endl;

}

i have two question .

question 1 > what is the full form of strstr() ?

for example, if i write strcpy ---> it means string copy.

similarly what is the meaning of strstr() ?

the syntaxex dont give the full form of this function. can you tell what is the literal meaning?


question 2.


without assigning a memory (by new keyword ) the code is running!!

look, i have simply tested with only char *s; but no memory allocated.
