Problem Statement - Output writing – Pointer to string elements

Find and write the output of the following C++ program code:
Note : Assume all required header files are already included in the program.

 

int main( )
{
  char str[]="NOCONFUSION";
  cout<<*str<<*(&str[2])<<endl;
  cout.write(str,2)<<endl;
  cout.write(str+2,9)<<endl;
  return 0;
}

 

Solution

TC++ #7704

Run Output 

NC

NO

CONFUSION

char str[ ]=”NOCONFUSION”;//This is c style string declaration
cout<<*str<<*(&str[2])<<endl;
Here *str will print the first character N and *(&str[2]) will print value at address of second character which is character C

cout.write(str,2)<<endl;
This will simply write 2 characters starting from first character which is NO.

cout.write(str+2,9)<<endl;
This will display 9 characters from second point in str pointer which is CONFUSION.
