Question

What will be the output of the program?

#include<stdio.h>

int main()
{
    char str = "CuriousTab";
    printf("%s\n", str);
    return 0;
}

Options
A. Error
B. CuriousTab
C. Base address of str
D. No output

Correct Answer

Error

Explanation

The line char str = "CuriousTab"; generates "Non portable pointer conversion" error.

To eliminate the error, we have to change the above line to

char *str = "CuriousTab"; (or) char str[] = "CuriousTab";

Then it prints "CuriousTab".
