Pointer to local variable

#include <iostream>
using namespace std;

char* func();

int main() {
    char* str;
    str = func();
    cout<<str;
    return 0;
}

char*  func() {
    char * str;
    char p[] = "priyanka is a good girl";
    str = p;
    cout<<str<<"\n";
    return str;
}

gives the output,

priyanka is a good girl

priy

I did not understand what just happened here, why an incomplete array was given as output. I am a little new with this. Please help.

Answer 1

In func2() char p[] is a local variable initialized on stack. Returning a pointer to stack variable is a bad idea(and is undefined behaviour as well), and I think your string “priyanka is a good girl” got overwritten when the function returned.
