A strong password should contain at least one digit, one lowercase letter, and one uppercase letter. Given below is a function that takes in a string and returns true if the string is a strong password and false otherwise. Fill in the spaces in the function implementation. Do not use ctype.h library.

Hint: In ASCII, each char corresponds to a number. The digit characters 0 through 9; the uppercase characters A through Z, and the lowercase letters a through z are consecutive.

bool IsValidPassword( char pswd[] )

{

bool hasLower=false, hasUpper=false, hasDigit=false;

int c, i=0;

while ( pswd[i] != '\0' )

{

c= (int) pswd[i];

if ( ....... ) // check if pswd[i] is lowercase

hasLower = true;

else if ( ....... ) // check if pswd[i] is uppercase

...... // update the correct boolean variable

else if ( ....... ) // check if pswd[i] is a digit

...... // update the correct boolean variable

..

}

if ( ..... )

return true;

else

return false;

}
